Introduction Foreword This manual is written for an experienced technician. Essential tools required in performing certain service work are identified in this manual and are recommended for use. Live with safety: Read the safety messages in the introduction of this manual and the cautions presented throughout the text of the manual. This is the safety-alert symbol. When you see this symbol on the machine or in this manual, be alert to the potential for personal injury. Technical manuals are divided in two parts: repair and diagnosis and tests. Repair sections tell how to repair the components. Diagnosis and tests sections help you identify the majority of routine failures quickly.

Information is organized in groups for the various components requiring service instruction. At the beginning of each group are summary listings of all applicable essential tools, service equipment and tools, other materials needed to do the job, service parts kits, specifications, wear tolerances, and torque values. Technical Manuals are concise guides for specific machines. They are on-the-job guides containing only the vital information needed for diagnosis, analysis, testing, and repair. Fundamental service information is available from other sources covering basic theory of operation, fundamentals of troubleshooting, general maintenance, and basic type of failures and their causes.

"Lubricated" means coated with a lubricant such as engine oil, or fasteners with phosphate and oil coatings.

b

"Dry" means plain or zinc plated without any lubrication.

DO NOT use these values if a different torque value or tightening procedure is given for a specific application. Torque values listed are for general use only. Check tightness of fasteners periodically.

Make sure fastener threads are clean and that you properly start thread engagement. This will prevent them from failing when tightening.

Shear bolts are designed to fail under predetermined loads. Always replace shear bolts with identical property class.

Tighten plastic insert or crimped steel-type lock nuts to approximately 50 percent of the dry torque shown in the chart, applied to the nut, not to the bolt head. Tighten toothed or serrated-type lock nuts to the full torque value.

Fasteners should be replaced with the same or higher property class. If higher property class fasteners are used, these should only be tightened to the strength of the original.

How To Use This Diagnostic Information General Information How to Use the Electrical Diagnostic Group All electrical systems on this machine are divided into functional systems. Each system has a Diagnostic Group. IMPORTANT: Troubleshoot the machine one problem at a time. Repairing one system’s problem may solve a problem in several other systems.

every two inches to facilitate identification. The Circuit Code Listing Group shows each wires circuit code, functional name and color. Some machine’s wires do not have circuit codes on them. Their only designation is wire color and pin location at the connector. • Diagnostics - provides a step by step approach to help the technician isolate the problem of the specific system being diagnosed. How to use the Diagnostic Procedures

NOTE: If it is determined that a problem is not in an electrical system, the diagnostic routine will refer you to the proper diagnostic group in the manual. Each Electrical Diagnostic Group is divided into the following parts: • Brief Description - provides a quick explanation of the system function. • Basic Operation - provides operational instructions of the systems’ basic features. • Detailed Description - describes the actual operation of the system. • Connector Locations - gives a pictorial description of the electrical connector locations on the machine. Connectors are identified by Connector Number. (See the Connector Identification Group for location photograph, pin numbers, circuit codes and repair procedures.) • Electrical Schematic - shows: – System Components - All components associated with the system operation. – Connectors - Every connector is given a Connector Number to aid in identification. The Connector Identification Group has been added to provide detailed connector location photographs, pin number/circuit code lists, mating face views and repair procedures. – Wiring Harnesses - All wiring harnesses associated with the system. – Circuit Codes - each wire in the machine’s wiring harness is marked with it’s circuit code number

The diagnostic procedures for this machine are written in a step-by-step format to help the technician isolate the failed components of the specific system being diagnosed. IMPORTANT: Troubleshoot the machine one problem at a time. Repairing one system’s problem may solve a problem in several other systems. NOTE: If it is determined that a problem is not in an electrical system, the diagnostic routine will refer you to the proper section of the manual. Things to remember when using diagnostic procedures: • Following each procedure step-by-step is very important. Skipping a step, or steps, could cause the technician to miss, overlook or possibly misdiagnose a possible problem. • Each test step contains all requirements for that test. This includes switch settings, connectors to be disconnected and checks to be performed. • Unless a test procedure says to disconnect a connector, leave connected and probe the rear of the connector to perform test. If a test segment says to disconnect a connector, disconnect and test the circuit as directed. • At the end of each test step, reconnect all components that have been disconnected.

• Many references in the diagnostic procedure will refer to 12 VDC. 12 VDC is a reference to battery voltage, but is not a specific voltage or exactly 12 Volts. A typical range of acceptable battery voltage is from 12.5 to 14.9 depending on battery state of battery charge and engine running or not. • For a voltage or resistance check, use the positive meter lead for the first test point specified and the negative meter lead on the second test point. • If a procedure directs you to replace a blown fuse and the new fuse immediately fails, use the schematic to trace and check all involved circuits for a shorted or grounded wire. General Electrical System Diagnostic Information

• Disconnect batteries prior to recharging (if possible) Why: Electrical loads in the machine can slow the recharging process. Battery chargers can cause electrical voltage spikes that can damage electronic components. • Never jump start the machine with a voltage higher than the machine is designed to operate on Why: This can damage electronic components • Do not connect or disconnect electrical connectors while the key switch is on or the machine is running. Why: This can cause computer system errors from interrupting a computer program while it is running and electrical voltage spikes that are produced can damage electronic components.

Electrical System Visual Inspection Visual inspection of the electrical system’s wiring harnesses and components for the following items can significantly reduce diagnostic time: • Mechanical damage to the wiring harness covering or harness itself • Disconnected or damaged connectors • Bare wires and/or shorts to ground • Loose wires and/or open circuits • Poor/corroded connections • Battery condition (terminal corrosion, voltage, cold cranking amperage capacity, electrolyte level) • Alternator condition (dirty, belt tension) • Overheated or discolored components Basic Electrical Component Handling / Precautions for Vehicles Equipped with Computer Controlled Systems • Never disconnect the batteries while the key switch is on and the engine is running. Why: This can cause electrical voltage spikes that can damage electronic components. • Do not connect jumper cables while the key switch is on. Why: This can cause electrical voltage spikes that can damage electronic components.

• Do not apply power or ground to any component as a test unless specifically instructed to do so. Why: Connecting the wrong voltage to the wrong point of an electronic system can cause electronic component failures. • When welding on the machine, make sure to connect ground lead to the parts being welded. For maximum protection disconnect all electronic controllers before welding. Why: The high currents associated with welding can damage wiring harnesses that are involved in the ground path. Welding can also cause electrical voltage spikes that can damage electronic components. Electrical Connector / Wiring Harness Handling and Repair • Electrical connectors must not be forcibly mated or un-mated. Why: The connectors have been designed to be mated easily. If you have to use tools or excessive force you may be doing something wrong. Prying on or forcing connectors may cause permanent damage to the locking mechanism, contacts or both. • When working on connectors make sure you are working on the correct terminal!

How To Use This Diagnostic Information Why: Measuring diagnostic values at the wrong connector terminal can lead to unnecessary part replacement. The male and female halves of an electrical connector are mirror images of each other and it is easy to confuse terminal locations. Look for the terminal identifier info on the connector body. • Use proper terminals for any connector repairs. Why: In some connectors different terminal materials are used (to carry different currents). If improper terminals or terminal materials are used future electrical problems may occur from corrosion or current carrying capacity. • When removing terminals from a connector body it is very important to use the proper extraction tool and procedure. Extraction tools are available through SERVICEGARD. Why: The connector body can be damaged if terminals are just "jerked" out. The damage caused by this action may not be readily visible, but may prevent new terminals from being properly retained and cause replacement of the connector body. • When installing a new terminal on a wire make sure the proper crimping tools is used. Why: Each part of the electrical terminal is designed for a specific purpose, failure to properly crimp the terminal can result in future electrical or mechanical problems. Terminal crimping tools are available through SERVICEGARD. It is important to make sure the insulation and wire crimps on each terminal are made properly. Soldering terminals is not recommended. See repair procedures in the Connector Repair Procedures Group • Soldering splices is not recommended. Why: Any repairs to wires in the harness should not allow moisture to come in contact with the actual copper conductor. Soldering a wire splice is not

recommended because a portion of stranded wire will become solid and can cause it to break in the future, especially if it is subject to movement. When repairing a broken wire in a wiring harness, use "Heat-Shrinkable" butt splices. Be careful not to place a splice in any section of the harness subject to motion or flexing. Diagnostic Schematic and Schematic Symbols Information

All electrical systems on this machine are divided into systems. Each system has a Diagnostic Schematic associated with it that provides a complete view of all associated components, connectors, terminal numbers, wiring harnesses, and ground points. An example is shown below. Diagnostic Schematics are provided to allow a technician to all the electrical components associated with a particular system on the machine. This schematic will allow you to follow the wiring from a component through all associated wiring harnesses to its final point of use. Only the terminals of a connector that are used are shown. Only the components of a system that are used are shown. Every ground point on this machine has been assigned a connector identifier number (X999) and location info is available in Section 240 Connector Information group of this technical manual.

Ask the Operator

• Other trouble signs

What work was the machine doing when the trouble was noticed? Is the trouble erratic or consistent? What did the operator do after the breakdown? Was an attempt made to fix the problem?

In general, look for anything unusual. Many electrical failures cannot be detected even if the machine is started. Therefore, a systematic and complete inspection of the electrical and electronic systems is necessary. Many times the problem can be detected without turning on a switch or starting the engine. While inspecting the electrical and electronics systems, make notes of all trouble signs.

These are just a few of the many questions a good troubleshooter will ask the operator. Often a passing comment by the operator will provide the key to the problem. Ask about how the machine is used and when it was last serviced. Many problems can be traced to poor periodic maintenance programs or abuse to the machine.

Carefully inspect the electrical and electronic components for possible clues to the malfunction. Check to see if the machine can be operated without further damage to the system.

Inspect the System Operate the Machine (if possible) Carefully inspect the electrical and electronic components for possible clues into the malfunction. Check to see if the machine can be operated without further damage to the system. Always check these items before turning on switches or running the machine. • Look for bare wires that could cause grounds or shorts and dangerous sparks. Shorted wires can damage the changing system. • Look for loose or broken wires. In the charging system they can damage the regulator. • Inspect all components, especially battery connection points. Acid film and dirt on the battery may cause current flow between the battery terminals, resulting in current leakage. Check the battery ground strap for proper connection. • Check the battery electrolyte level. Continued loss of electrolyte indicates overcharging. • Check the alternator drive belt tension. • Inspect for overheated parts after the machine has been stopped for awhile. They will often smell like burnt insulation. Put your hand on the alternator or regulator. Heat in these parts when the machine has not been operated for some time is a sure tip-off to charging circuit problems.

If your inspection shows that the machine can be run, first turn the Key Switch to the ACCESSORY position. Try out the accessory circuits - lights, lighter, etc. How do each of these circuit work? Turn the Key Switch to the ON position. Do the proper indicator lights come on in the Warning Display Panel? Start the machine. Check all gauges and indicators for proper operation. Operate the troubled system. Look for improper operation. List the Possible Causes Make a list of the possible causes. What were the signs you found while inspecting the machine? What is the most likely cause? Are there other possibilities? Remember that one failure often causes another. Reach a Conclusion Look over you list of possible causes and decide which are the most likely and which are the easiest to verify.

CCS Auxiliary Hydraulics Coupler Seed Delivery Fan Switch Diagnostics Theory of Operation The Auxiliary Hydraulic Optional Kit can be installed on a planter to allow the operator to use a hydraulic orbital motor for attachments at the rear of the planter such as a fill auger or conveyer to fill the CCS system with seed. The operator plugs in the hydraulic hoses of the fill system into the hydraulic couplers at the rear of the planter and activates the tractor SCV that controls the CCS Seed Delivery System Fan. The operator moves the hydraulic diverter valve to direct oil to the orbital motor of the fill system. The electrical switch at the rear of the planter is moved to shut off oil flow to the CCS Seed Delivery Fan Solenoid (Y14) causing the oil to flow to the auxiliary couplers and back to the tractor SCV. To install the Auxiliary Hydraulics Kit, the CCS Seed Delivery Fan Solenoid is disconnected and the wiring harness for the Auxiliary Hydraulic Kit is installed into

that harness at X420. This harness directs the power wire that originally went to the CCS Seed Delivery Fan through a switch (S12), and on to the CCS Seed Delivery Fan. The ground wire goes directly from the X420 to the CCS Seed Delivery Fan Solenoid X507. The switch allows the operator to shut off power to the CCS Seed Delivery Fan by moving the S12 Switch located at the rear of the planter. After the operator finishes using the Auxiliary Hydraulic Kit, the hydraulic diverter valve and S12 switch must be placed back to the original position so that the CCS Fan will once again operate while planting. NOTE: Planters equipped with a Drawbar Hitch require a 7 Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) and Planter Frame Extension Harness (W311) not referenced in this information. Refer to the individual Group for each harness for more information.

Group 15D

CCS Seed Delivery Agitator Diagnostics Theory of Operation Each central tank on a 1770NT equipped with CCS contains an agitation device which helps prevent “seed bridging” or “plugging” when using heavily treated or inoculated seed. The agitation device consists of a steel shaft with spring clips inserted through it and runs the width of the bottom of the tank. The shaft moves in a forward and reverse motion, similar to that of a windshield wiper shaft. In order for the CCS Seed Delivery Agitator Motors to run, the tractor’s Key Switch must be in the ON position and the planter must be completely unfolded and lowered to the ground. Plant Mode, Planter Lowered: With the Key Switch in the ON position, 12 VDC supplied by the tractor is directed from connector X301 (7 pin Trailer Lighting and Accessory Outlet) on pin 7 (Red wire). It then directs 12 VDC to: the CCS Push Button Shut Off Switch (S5) on pin A of X419, and the CCS Agitator Motor Relay (K31) on pin 30 of X427. When the planter is completely unfolded and lowered, S5 is closed and voltage is able to exit the switch on pin B as a Black wire. 12 VDC on the Black wire is directed through a splice to a Red wire to pin A of X420 at the CCS Seed Delivery Fan Hydraulic Motor Solenoid (Y14). The CCS Delivery Fan Hydraulic Motor Solenoid (Y14) is directed to ground through pin B of X420 by a Black wire to the 7 pin Trailer Lighting and Accessory Outlet (X301), pin 1. This completes the circuit allowing current to flow and energize the solenoid. If continuous hydraulic flow is present, the fan is able to turn. Voltage is also available from S5 through a splice to a Red/White wire to pin 85 of the CCS Agitator Motor Relay (K31), X427. The CCS Agitator Motor Relay (K31) is grounded through pin 86 of X427 by a Black wire to the 7 pin Trailer Lighting and Accessory Outlet (X301), pin 1. This completes the circuit allowing current to flow and energize the relay. When the CCS Agitator Motor Relay (K31) becomes energized,

voltage supplied to pin 30 of the relay from pin 7 of the 7 pin Trailer Lighting and Accessory Outlet (X301) is able to exit the relay through pin 87 on a White/Black wire. The White/Black wire directs voltage to pin A of X434 to the Right Agitation Motor 15 amp Fuse (F5), exiting pin B on a Lt. Green/White wire to pin B of X429 to the Right Agitation Motor (M5). Voltage from the Right Agitation Motor (M5) is directed to X441/X442 junction eyelet terminal, then through a Black wire to ground at pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301). This completes the circuit allowing current to flow and the motor to turn. Voltage from the White/Black wire is also able to pin A of X433 to the Left Agitation Motor 15 amp Fuse (F4), exiting pin B on a Red/White wire to pin B of X428 to the Left Agitation Motor (M4). Voltage from the Left Agitation Motor (M4) is directed to X443/X444 junction eyelet terminal, then through a Black wire to ground at pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301). This completes the circuit allowing current to flow and the motor to turn. Purge Hoses Mode, Planter Raised: With the Key Switch in the ON position, 12 VDC supplied by the tractor is directed from connector X301 (7 pin Trailer Lighting and Accessory Outlet) on pin 7 (Red wire). It then directs voltage to: the CCS Clean Out Switch (S8) on pin A of X431, the CCS Agitator Motor Relay (K31) on pin 30 of X427, and the CCS Fan Motor Shut Off Relay (K33) on pin 30. When the CCS Clean Out Switch is in the Purge Hoses Mode, S8 is closed and 12 VDC is able to exit the switch on pin B as a Black wire. 12 VDC is directed on the Black wire to a splice with a Black/Green wire to pin 85 of the CCS Fan Motor Shut Off Relay (K33), X438. K33 is directed to ground through pin 86 of X438 by a Black wire to the 7 pin Trailer Lighting and Accessory Outlet (X301), pin 1. This completes the circuit allowing current to flow to energize the relay.

IF EQUIPPED WITH A DRAWBAR HITCH; • 7-Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) Connector X512 and X513 • Planter Frame Extension Harness (W311) Connector X510 and X511. IMPORTANT: Harnesses W311 and W312 are not shown on the following schematic. Refer to individual Group for each harness for diagnostic information before continuing. Hydraulic connection to tractor; • Hoses connected to correct SCV • Hoses connected to correct SCV extend/retract ports • Correct hose tips IMPORTANT: Seeding equipment harnesses are grounded to tractor and NOT the implement frame. When referencing frame ground in the following diagnostic steps, be sure there is continuity between the tractor battery negative (-) terminal and the implement frame. Once continuity is verified from battery (-) to implement frame, the implement frame may be used as frame ground to troubleshoot. Are all electrical and hydraulic connections to planter made correctly? – – –1/1

Group 15E

CCS Seed Delivery Fan Diagnostics Theory of Operation Plant Mode: With the CCS Seed Delivery System, a hydraulically driven fan provides airflow for seed delivery from a central tank to a hopper on the row unit. The CCS Seed Delivery acts as a tender for the row units. It provides a small pool of seed to each row unit at all times to supply the needs of the meter. Singulation of the seed is still handled by a meter at the row unit to maintain consistent and accurate seed spacing. In order for the CCS Seed Delivery Fan to operate the tractor’s Key Switch must be in the ON position, and the planter must be completely unfolded and lowered to the ground. Also, the appropriate tractor SCV associated with the Field Raise/Lower circuit must be in the lower detented position and supplying adequate hydraulic flow. With the Key Switch in the ON position, 12 VDC supplied by the tractor is directed through connector X301 (7 pin Trailer Lighting and Accessory Outlet) on pin 7 (Red wire) to the CCS Push Button Shut Off Switch (S5) on pin A of X419. When the planter is completely unfolded and lowered, S5 is closed. Voltage is able to exit the switch on pin B as a Black wire. The Black wire is spliced to a Red wire connected to pin A of X420 at the CCS Seed Delivery Fan Hydraulic Motor Solenoid (Y14). The CCS Seed Delivery Fan Solenoid is directed to ground through pin B (X420) to pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301). This completes the circuit allowing current to flow and energize the solenoid. If continuous hydraulic flow is present, the fan is able to turn. Electrical current on the Red/White wire also flows to the CCS Agitator Motor Relay and associated agitator motor circuits causing the Seed Agitators to turn. Purge Hoses Mode:

For CCS hopper clean out purposes, the CCS Seed Delivery Fan can be turned on while the planter is fully raised. This is done by selecting: the Plant position on the Plant/Transport Mode Switch (S101) of the Frame Control Console, the Purge Hoses position on the CCS Clean Out Switch (S8, located near the Vacuum Gauge on the planter), and positioning the tractor’s SCV associated with the Field Raise/Lower Circuit to the lower detented position. This supplies continuous hydraulic flow to the CCS Seed Delivery Fan without lowering the planter. With the Key Switch in the ON position, 12 VDC supplied by the tractor is directed through connector X301 (7 pin Trailer Lighting and Accessory Outlet) on pin 7 (Red wire). It then is directed to: the CCS Clean Out Switch (S8) on pin A of X431, and the CCS Fan Motor Shut Off Relay (K33) on pin 30 of X438. When S8 is in the Purge Hoses position, the switch is closed. Voltage exits the switch on pin B as a Black wire. The Black wire is spliced to at Black/Green wire connected to pin 85 of the CCS Fan Motor Shut Off Relay (K33), X438. The CCS Fan Motor Shut Off Relay (K33) is directed to ground through pin 86 (X438) by a Black wire to pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301). This completes the circuit allowing current to flow and energize the relay. When K33 becomes energized, voltage is able to exit the relay through pin 87 on a Red/White wire. The Red/White wire is spliced to a Red wire connected to pin A of X420 at the CCS Seed Delivery Fan Hydraulic Motor Solenoid (Y14). The solenoid is directed to ground through pin B (X420) to pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301). This completes the circuit allowing current to flow and energize the solenoid. If continuous hydraulic flow is present, the fan is able to turn. Electrical current on the Red/White wire also flows to the CCS Agitator Motor Relay and associated agitator motor circuits causing the Seed Agitators to turn.

CCS Seed Delivery Fan Diagnostics When S8 is in the Purge Hoses position (switch closed), 12 VDC is also directed from pin B (X431) on a Black wire. The Black wire is spliced to a Black/Green connected to pin 85 (X437) of the Clean Out Mode Relay (K32). The Clean Out Mode Relay (K32) is directed to ground through pin 86 (X437) by a Black wire to pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301). This completes the circuit allowing current to flow and energize the relay. The circuit to the CCS Center Frame Field Raise/Lower

and Transport Raise/Lower Solenoid (Y1) is opened and the planter’s raise/lower function is disabled. NOTE: Planters equipped with a Drawbar Hitch require a 7 Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) and Planter Frame Extension Harness (W311) not referenced in this information.

Group 15F

CCS Tank Fill Lights Diagnostics Theory of Operation Electrical power is supplied to the CCS Tank Fill Lights through Pin 2 of the 7 Pin Trailer Lighting and Accessory Outlet Connector at the rear of the tractor. Pin 2 of the 7 Pin Trailer Lighting and Accessory Outlet Connector is powered whenever the tractor light switch is in a position to allow the flood lights to come on. On most tractors, power is available on Pin 2 of the 7 Pin Trailer Lighting and Accessory Outlet Connector whenever the tractor light switch is in either the Field 1 or Field 2 position. Refer to the Operators Manual of the tractor you are using for details of the light switch position required to get power to the CCS Tank Fill Lights (Pin 2). The “Auxiliary Lights” connector is provided on the machine to give the operator the ability to add optional or additional field/flood lights on the planter. With the tractor light switch in the proper position, Pin 2 of the 7 Pin Trailer Lighting and Accessory Outlet Connector (X301) provides 12 VDC power on the Red wire while Pin 1 provides ground on the Black wire to the “Aux. Lights” X310.

Voltage exiting Pin 2, of the 7 Pin Trailer Lighting and Accessory Outlet (X301) flows to Pin A of the “Aux. Lights”, X310. Power from Pin A (X310) travels to the CCS Tank Fill Light Switch on the Red wire and enters S11 on Pin A (X314). When the CCS Tank Fill Light Switch is in the ON Position, 12 VDC is directed to both CCS Tank Fill Lamps on Pin A, illuminating the Lamps. The ground circuit is completed by the Black wire which extends from each Tank Fill Lamp, X312 and X313 (Pin B), through the “Aux. Lights” Connector, X310 (Pin B) and into the 7 Pin Trailer Lighting and Accessory Outlet Connector (X301, Pin 1). NOTE: Planters equipped with a Drawbar Hitch require a 7 Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) and Planter Frame Extension Harness (W311) not referenced in this information. Refer to the individual Group for each harness for more information.

Group 15G

CCS Tank Low Warning Diagnostics Theory Of Operation The Tank Low Warning system alerts the operator when the bulk seed tanks are near empty by activating a red warning lamp on the Frame Control Console. With the tractor key switch in the ON position, 12 VDC flows on the Red wire from connector X301 (7-Pin Trailer Lighting and Accessory Outlet) on Pin 7 to the Frame Control Power Fuse F3 and on to X402, Frame Control Console (Pin A) . Current also flows on the Red wire to connectors X417, Left Bin Level Sensor (Pin 1) and X418, Right Bin Level Sensor (Pin 1). The Ground Circuit is completed through the Black wire on Pin 1 of X301 (7-Pin Trailer Lighting and Accessory Outlet). The Black wire that enters X301 is connected to: Pin 2 of X417, Left Bin Level Sensor, Pin 2 of X418, Right Bin Level Sensor, Pin V of X401, Frame Control Console Extension Harness and Pin J of Frame Control Console. The Left Bin Level Sensor lamp signal exits connector X417 on the Lt. Blue wire (Pin 3) and the Right Bin Level Sensor lamp signal exits connector X418 on the Lt. Blue wire (Pin 3). Both Lt. Blue signal wires are spliced together in the Frame Harness and flow through connector X401, Frame Harness to Frame Control Console Extension Harness on Pin U. In the Frame Control Console Extension Harness, the signal wire becomes circuit code “SLVL” and enters the Frame Control Console on Pin K.

The Bin Level Sensors in each tank are optical sensors. When the seed covers the face of the sensor, the sensor allows current to flow on the signal wire, equally supplying voltage (12 VDC) to the Frame Control Console. As the tanks empty and the face of the sensor for either tank is uncovered, the current flowing on the signal wire is reduced by the sensor to less than 0.5 VDC. As the current flow drops on either the Left or Right Bin Level Sensor to less than .5 VDC, the circuitry in the Bin Level Sensors causes the voltage on the sensor wire leading into the Frame Control Console to drop to less than 0.5 VDC. The Lamp Drive Circuit on the Printed Circuit Board in the Frame Control Console senses the loss of voltage (less than 0.5 VDC) and turns ON the Tank Low Warning Lamp when either one of the sensors are uncovered. The optical sensors need to be kept clean for the system to work properly. NOTE: Planters equipped with a Drawbar Hitch require a 7 Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) and Planter Frame Extension Harness (W311) not referenced in this information. Refer to the individual Group for each harness for more information.

Group 15I

Drawbar Hitch/Independent Marker Diagnostics Theory of Operation The optional Drawbar Hitch is available to allow the planter to be attached to the tractor drawbar instead of the 3 point hitch. This allows the planter to be operated on a tractor without a rockshaft. The Drawbar Hitch is used in place of the rockshaft on a tractor to raise and lower the planter hitch, allowing the operator to unlatch or latch the wings of the planter between folding and unfolding operations. The Drawbar Hitch is also used to increase transport height of the tongue of the planter. The operator can select from an independent control console in the tractor cab either the Drawbar Hitch function or the Independent Marker function. The same tractor SCV is used for either Drawbar Hitch or Independent Marker function, but is separate from other planter functions. The Drawbar Hitch receives power and ground from the Tractor Convenience Outlet. The Convenience Outlet Power Extension and Drawbar Hitch/Marker Switch Harness (W310) connects into the Tractor Convenience Outlet. The harness also supplies another Convenience Outlet, which can be used to supply power to other electrical systems that may be needed. With the Key Switch in the ON position, 12 VDC supplied by the tractor is directed through X501

(Tractor Convenience Outlet) pin 1 (Switched Power, Red wire) to the Drawbar Hitch/Independent Marker Switch (S107). With the Drawbar Hitch/Independent Marker Switch (S107) in the Drawbar Position (switch closed), power is directed on a Red/White wire through the Convenience Outlet Power Extension and Drawbar Hitch/Marker Switch Harness (W310) to X508, pin 2. Power is then directed on a Red/White wire through the Drawbar Hitch/Independent Marker Harness (W309) to X472 pin A of the Drawbar Hitch/Independent Marker Solenoid #1 (Y26). The solenoid is directed to ground through pin B of X472 by a Black wire to pin 3 of X508, then to pin 3 of X501. This completes the circuit and allows the current to flow, energizing the solenoid. Power is also directed on a Red/White wire to X473 pin A of the Drawbar Hitch/Independent Marker Solenoid #2 (Y27). The solenoid is directed to ground through pin B of X473 by a Black wire to pin 3 of X508, then on to pin 3 of X501. This completes the circuit and allows the current to flow, energizing the solenoid. With both of the solenoids energized, oil is directed to the Drawbar Hitch Cylinder (C17) instead of the marker system when the tractor SCV is activated. When the solenoids are not energized, oil in the Drawbar Hitch Cylinder is trapped and oil is directed to the Independent Markers when the appropriate tractor SCV is activated.

Group 15J

Field Raise/Lower Diagnostics Theory of Operation The Frame Control Console Switches operate solenoid hydraulic valves. The solenoid valve prevents a cylinder from operating unless valve is energized. The functions are selected with the corresponding switches and controlled with the tractor selective control valve(s). The operator can raise and lower the planter when it is unfolded and in the field position by pressing the Plant-Trans mode switch to the Plant position and activating the appropriate tractor SCV. Each time the planter is fully lowered, the Center and Wing Wheel Cylinders rephase and the unfold hydraulic circuit is charged to ensure that the fold cylinders maintain the fully extended position. If the Marker Raise/Lower system is setup as automatic control, the markers have the ability to alternately raise and lower each time the planter is raised and lowered. With the Key Switch in the ON position, 12 VDC supplied by the tractor is directed from connector X301 (7 pin Trailer Lighting and Accessory Outlet) on pin 7 (Red wire) to: pin 30 of the Plant Mode Raise/Lower Relay (K35), and to pin B of X401. Voltage from pin B is directed to the Frame Control Console Extension Harness (W301), and to Fuse (F3) as cc# 011A. 12 VDC exits Fuse (F3) on CC# 11 and is directed to the Frame Control Console (A301), pin A of X402. Voltage is then directed to the Plant/Transport Mode Switch (S101), pin C. With the Plant/Transport Mode Switch in the Plant position, voltage exits the switch on pin 1 and is directed to the Machine Transport Mode Relay (K30) on pin 9 and exits on pin 1. 12 VDC then exits the Frame Control Console (A301) at pin G of X402 on cc# PLNT of the Frame Control Console Extension Harness (W301), and enters the Frame Harness (W302) at pin F of X401 (Dark Green/Black wire). The Dark Green/Black wire directs 12 VDC to pin 85 of the Plant Mode Raise/Lower Relay (K35). The relay (K35) is directed to ground through pin 86 of X446 by a Black wire to pin 1 of X301 of the 7 pin Trailer Lighting and Accessory Outlet. This completes the circuit and allows current to flow, energizing the relay. 12 VDC is then directed through the relay, exiting on pin 87 to a

Dark Blue wire. The Dark Blue wire splices with Red wires leading to pin A of: connector X448 Plant Mode Raise/Lower Solenoid #1 (Y18), connector X449 Plant Mode Raise/Lower Solenoid #2 (Y19), connector X450 Plant Mode Raise/Lower Solenoid #3 (Y20), connector X451 Plant Mode Raise/Lower Solenoid #4 (Y21). Each of the Plant Mode Raise/Lower Solenoids (Y18, Y19, Y20, Y21) is directed to ground through pin B (of X448, X449, X450, X451) by a Black wire to pin 1 of X301 of the 7 pin Trailer Lighting and Accessory Outlet. This completes the circuit and allows current to flow, energizing each solenoid. Voltage from the Dark Green/Black wire also goes to a diode (DA1) spliced into the harness. 12 VDC exits the DA1 diode on a Red/Green wire to pin A of X405. Voltage is directed from pin A of X405 on a Brown wire to the Single Throw, Triple Pole Switch Assembly (S3). Since the switch is closed in the unfolded position, 12 VDC is directed on a Red wire from the switch to pin B of X405. Voltage is directed from pin B on X405 on a Tan wire to a splice to a Red wire connected to pin A of X409 of the Fold/Unfold Solenoid (Y8). The Fold/Unfold Solenoid (Y8) is directed to ground through pin B of X409 by a Black wire to pin 1 of X301 of the 7 pin Trailer Lighting and Accessory Outlet. This completes the circuit and allows current to flow, energizing the solenoid. 12 VDC exiting the Plant/Transport Mode Switch (S101) on pin 1 also is directed to the Frame Control Console (A301) through pin C of X402. 12 VDC then is directed on the Frame Control Console Extension Harness (W301) on cc “Y1” to the Frame Harness (W302), pin N of X401. Voltage is directed from pin N on a Pink wire to pin A of X411 at the Center Frame, Field Raise/Lower, and Trans. Raise/Lower Solenoid (Y1). The Center Frame, Field Raise/Lower, and Trans. Raise/Lower Solenoid (Y1) is directed to ground through pin B of X411 by a Black wire to pin 1 of X301 of the 7 pin Trailer Lighting and Accessory Outlet. This completes the circuit and allows current to flow, energizing the solenoid.

Field Raise/Lower Diagnostics with CCS Theory of Operation The Frame Control Console Switches operate solenoid actuated hydraulic valves. The solenoid valve prevents a cylinder from operating unless the valve is energized. The functions are selected with the corresponding switches and controlled with the tractor selective control valve(s). The operator can raise and lower the planter when it is unfolded to the field position by pressing the Plant-Trans mode switch to the Plant position, selecting Plant-Clean Out mode on the CCS Clean Out Switch (located near the Vacuum Gauge on the planter), and activating the appropriate tractor SCV. Each time the planter is fully lowered, the Center and Wing Wheel Cylinders rephase and the unfold hydraulic circuit is charged to ensure that the fold cylinders maintain the fully extended position. If the Marker Raise/Lower system is setup as automatic control, the markers have the ability to alternately raise and lower each time the planter is raised and lowered. With the Key Switch in the ON position, 12 VDC supplied by the tractor is directed to X301 (7 pin Trailer Lighting and Accessory Outlet), pin 7 (Red wire). Voltage is then available to pin B, X401 of the Frame Control Console Extension Harness (W301) and to Fuse (F3) as cc #011A. 12 VDC exits Fuse (F3) on CC# 11 and is directed to the Frame Control Console (A301), pin A, X402. Voltage is then directed to the Plant/Transport Mode Switch (S101), pin C. With the Plant/Transport Mode Switch in the Plant position, 12 VDC exits the switch on pin 1 and is directed to pin 9 of the Machine Transport Mode Relay (K30). Voltage exits K30 at pin 1 and is directed to the Frame Control Console (A301), pin G of X402. 12 VDC is directed from pin G (X402) by cc# PLNT of the Frame Control Console Extension Harness (W301) to the Frame Harness (W302), pin F of X401 (Dark Green/Black wire). The Dark Green/Black wire directs voltage to diode (DA1) spliced into the harness. 12 VDC exits the DA1 diode on a Red/Green wire to pin A, X405.

Voltage is directed from pin A, X405 by a Brown wire to the Single Throw, Triple Pole Switch Assembly (A303). Since the switch is closed in the unfolded position, 12 VDC is directed on a Red wire to pin B, X405. Supply is directed from pin B, X405 by a Tan wire to a splice with a Red wire then on to pin A, X409 of the Fold/Unfold Solenoid (Y8). The Fold/Unfold Solenoid (Y8) is directed to ground by pin B, X409 by a Black wire to pin 1 of X301 of the 7 pin Trailer Lighting and Accessory Outlet, energizing the solenoid. 12 VDC exiting the Plant/Transport Mode Switch (S101), pin 1 also is directed to the Frame Control Console (A301), pin C (X402). Voltage is directed on the Frame Control Console Extension Harness (W301), cc “Y1”, to the Frame Harness (W302), pin N of X401. 12 VDC is directed from pin N (X401) by a Pink wire to pin 30 of the Clean Out Mode Relay (K32). Voltage exits the unenergized relay at pin 87a on a Pink/Black wire. The Pink/Black wire is spliced to a Red wire leading to pin A (X411) of the Center Frame, Field Raise/Lower, and Trans. Raise/Lower Solenoid (Y1). 12 VDC entering the Center Frame, Field Raise/Lower, and Trans. Raise/Lower Solenoid (Y1) is directed to ground through pin B of X411 by a Black wire to pin 1, X301 of the 7 pin Trailer Lighting and Accessory Outlet, energizing the solenoid. The operator is able to raise or lower the planter with the tractor Raise/Lower SCV. Clean Out Mode: A clean out mode is provided to allow the operator to clean out the hoppers while the machine is in the raised position. The raise/lower function is disabled when the operator is utilizing the Purge Hoses mode. Since it is necessary to supply the CCS fan to purge all the seed delivery hoses in the Purge Hoses mode, the operator is required to move the SCV lever to the lower detent position.

12 VDC is directed from pin 7 (X301) of the 7 pin Trailer Lighting & Accessory Outlet by a Red wire to pin A (X431). When the operator activates the CCS Clean Out Switch (S8) to the Purge Hoses position, the switch closes, allowing voltage to exit the switch at pin B, (X431). 12 VDC is directed from pin B (X431) by a Black wire to a splice with a Black/Green wire, then to pin 85 of the Clean Out Mode Relay (K32). The Clean Out Mode Relay (K32) is directed to ground through pin 86 of X437 by a Black wire to pin 1, X301 of the 7 pin Trailer Lighting and Accessory Outlet, energizing the relay. When the relay is energized, power to the Center Frame, Field Raise/Lower, and Trans. Raise/Lower Solenoid (Y1) is interrupted. With

no current available to the Y1 Solenoid, the operator is not able to raise or lower the planter. This allows the operator to put the Raise/Lower SCV into the lower detent position to operate the CCS Fan Motor, but not allow the planter to lower (for proper planter clean out). NOTE: Planters equipped with a Drawbar Hitch require a 7 Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) and Planter Frame Extension Harness (W311) not referenced in this information. Refer to the individual Group for each harness for more information.

Group 15L

Half Width Disconnect - Left Clutch Engage-Disengage Diagnostics

Theory of Operation The operator has the ability to disconnect the drive on the left side of the machine for planting point rows. The left clutch is disengaged by pressing the R-L clutch mode switch to the L position. When 12 VDC are sent to the clutch, it disengages. With the Key Switch in the RUN position, 12 VDC supplied by the tractor flows through connector X301 (7 pin Trailer Lighting and Accessory Outlet) on pin 7 (Red Wire). It then routes through pin B of X401, into the Frame Control Console Extension Harness (W301), and across Fuse (F3) as cc# 11 and enters pin A of X402 at the Frame Control Console (A301). It then flows to pin 5 of the Right/Left Clutch Disengage Switch (S105). With the Right/Left Clutch Disengage Switch in the Left detent, electrical current exits the switch on pin 2.

12 VDC from the Right/Left Clutch Disengage Switch exits the Frame Control Console (A301) through pin N of X402 on cc# LCL, travels across the Frame Control Console Extension Harness (W301), and enters pin P of X401 of the Frame Harness (W302), exiting as a White Wire. The White Wire changes to a Red wire and enters pin A of X415 at the Left Clutch (Y17), disengaging the clutch. NOTE: Planters equipped with a Drawbar Hitch require a 7 Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) and Planter Frame Extension Harness (W311) not referenced in this information. Refer to the individual Group for each harness for more information.

Half Width Disconnect - Right Clutch Engage-Disengage Diagnostics

Theory of Operation The operator has the ability to disconnect the drive on the right side of the machine for planting point rows. The right clutch is disengaged by pressing the R-L clutch mode switch to the R position. When 12 VDC are sent to the clutch, it disengages. With the Key Switch in the RUN position, 12 VDC supplied by the tractor flows through connector X301 (7 pin Trailer Lighting and Accessory Outlet) on pin 7 (Red Wire). It then routes through pin B of X401, into the Frame Control Console Extension Harness (W301), and across Fuse (F3) as cc#011. CC#011 enters the Frame Control Console (A301) on pin A of X402. It then flows to the Right/Left Clutch Disengage Switch (S105) on pin 5. With the Right/Left Clutch Disengage Switch in the Right detent, electrical current exits the switch on pin 1.

12 VDC from the Right/Left Clutch Disengage Switch exits the Frame Control Console (A301) through pin M of X402 on cc# RCL, travels across the Frame Control Console Extension Harness (W301), and enters the Frame Harness (W302) on pin M of X401 (Gray Wire). The Gray Wire changes to a Red wire, and enters X414 of Right Clutch (Y16) through pin A, disengaging the clutch. NOTE: Planters equipped with a Drawbar Hitch require a 7 Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) and Planter Frame Extension Harness (W311) not referenced in this information. Refer to the individual Group for each harness for more information.

Half Width Disconnect - Left Fertilizer Valve Diagnostics Theory of Operation The operator has the ability to divert the fertilizer on the left side of the machine back to the pump inlet for planting point rows. The left fertilizer is disengaged by pressing the R-L mode switch to the L position. 12 VDC are then sent to the valve motor that diverts the fertilizer. With the Key Switch in the RUN‘ position, 12 VDC supplied by the tractor flows through X301 (7 pin Trailer Lighting and Accessory Outlet) on pin 7 (Red Wire). It then routes through pin B of X401, into the Frame Control Console Extension Harness (W301), and across Fuse (F3) as cc#011 and enters pin A of X402 at the Frame Control Console (A301). It then flows to pin 5 of the Right/Left Clutch Disengage Switch (S105). With the Right/Left Clutch Disengage Switch in the Left detent, electrical current exits the switch on pin 2. 12 VDC from the Right/Left Clutch Disengage Switch exits the Frame Control Console (A301) through pin N of X402 on cc# LCL, travels across the Frame Control

Console Extension Harness (W301), and enters pin P of X401 of the Frame Harness (W302), exiting as a White Wire. The White Wire changes to a Green wire and enters pin A of X458 at the Left 3-Way Fertilizer Valve Motor (M7), closing the valve. The motor valve assembly contains limit switches that shut off the motor when the limit of rotation is reached. Voltage is continuously sent to the motor valve with the limit switch breaking the circuit. When the operator selects the opposite rotation of the valve, the limit switch would also stop operation; however, ground is provided by a third ground wire until the limit switch is again closed. NOTE: Planters equipped with a Drawbar Hitch require a 7 Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) and Planter Frame Extension Harness (W311) not referenced in this information. Refer to the individual Group for each harness for more information.

When the operator selects the opposite rotation of the valve, the limit switch would also stop operation; however, ground is provided by a third ground wire until the limit switch is again closed. NOTE: Planters equipped with a Drawbar Hitch require a 7 Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) and Planter Frame Extension Harness (W311) not referenced in this information. Refer to the individual Group for each harness for more information.

Lighting Overall Diagnostics Theory of Operation This machine is equipped with warning lights, tail lamps, and turn signals used to alert approaching traffic of the machine’s presence. The lighting harness plugs directly into the planter’s frame harness. The frame harness which is plugged into the 7 pin Trailer Lighting and Accessory Outlet, extends the turn signal, warning and tail light circuits to the rear of the planter.

and Accessory Outlet), and passes through pin A of X304. It is then distributed to pin B of X307 at the Right Red Tail Lamp (E302) and pin B of X308 at the Left Red Tail Lamp (E303). The current to the tail lights does not change when any of the other lighting functions are used. Right Turn:

Using the lighting controls and turn signals in the tractor, the operator controls the lighting on the planter. The lighting system includes turn signals, tail, and warning lights. There is also a connector at the rear of the machine to extend the lighting to a wagon if equipped with lights. A lighting enhancement (A302) module has been incorporated into the lighting circuit. This module causes red tail lights to function as turn signals. During normal transport, both amber lights will flash in unison at high intensity and both red lamps will illuminate steady at low intensity. When a turn is signaled, the red tail lamp in direction of turn will flash at high intensity in unison with the amber lamp. The opposite side amber and red lamps will illuminate steady at high intensity. Power for the individual lighting circuits is supplied through the 7 pin Trailer Lighting and Accessory Outlet connector X301. The Black Ground Wire enters on pin 1 of X301, routes through pin C of X302, branches to pin 1 of X303 (7 pin Trailer Lighting and Accessory Outlet), and passes through pin C of X304. It is then distributed to each component on the harness including the Flasher Module (A302), Right Amber Hazard Lamp (E301), Right Red Tail Lamp (E302), Left Red Tail Lamp (E303), and the Left Amber Hazard Lamp (E304). Current for the tail lights also enters through connector X301 on pin 6 (Tan Wire), routes through pin A of X302, branches to pin 6 of X303 (7 pin Trailer Lighting

Flashing current enters through connector X301 on pin 5 as a Dark. Green Wire, routes through pin B of X302, branches to pin 5 of X303 (7 pin Trailer Lighting and Accessory Outlet), and passes through pin B of X304. The flashing current is then distributed to pin A of X307 as a Green Wire at the Right Red Tail Lamp (E302), pin B of X306 at the Right Amber Hazard Lamp (E301), and pin D of X305 at the Flasher Module (A302). Steady current enters through connector X301 on pin 3 as a Yellow Wire, routes through pin D of X302, branches to pin 3 of X303 (7 pin Trailer Lighting and Accessory Outlet), and passes through pin D of X304. The steady current is then distributed to pin A of X308 at the Left Red Tail Lamp (E303), pin B of X309 at the Left Amber Hazard Lamp (E304), and pin C of X305 at the Flasher Module (A302). In the flasher module, steady current from the Yellow Wire closes the relay and creates ground circuits at pins E and B for the Green/Black and Yellow/Black Wires. Grounded by the Green/Black Wire, flashing current on the Green Wire is allowed to flow and flash the Right Red Tail Lamp (E302). Grounded by the Yellow/Black Wire, steady current on the Yellow Wire is allowed to flow and steadily illuminate the Left Red Tail Lamp (E303). Left Turn:

Group 15Q

Machine Fold-Unfold Diagnostics Theory of Operation The Frame Control Console Switches operate solenoid actuated hydraulic valves. The solenoid valve prevents a cylinder from operating unless the valve is energized. The functions are selected with the corresponding switches and controlled with the tractor selective control valve(s). For ease of transportation, the planter’s wings fold forward to the transport position and the machine is towed like a two-wheeled cart behind the tractor. The machine is folded by: pressing the Plant-Trans mode switch to the Trans position, holding the Wing Wheels-Fold mode switch to the Fold mode position, and activating the SCV until the machine is folded. Once folded, the tractor’s three point hitch is raised to engage the wing frame latch hooks. After the wings are latched, the tractor’s three point hitch is fully raised and the wing wheels are fully retracted. IMPORTANT: Do not fully raise the tractor’s three point hitch while folding or unfolding. Structural damage to machine may result. NOTE: It may be necessary to lower the tractor’s three point hitch so the wing latch hooks will clear the hitch tube when folding and unfolding. The machine is unfolded by: lowering the wing wheels, lowering the tractor’s three point hitch until the hitch tube is below the wing latch hooks, unlatching the wings, pressing the Plant-Trans mode switch to the Trans position, holding the Wing Wheels-Fold mode switch to the Fold mode position, and activating the SCV until the machine is completely unfolded.

pin Trailer Lighting and Accessory Outlet) pin 7 (Red wire) to pin B of X401 into the Frame Control Console Extension Harness (W301), and to Fuse (F3) as cc# 011A. Voltage exits Fuse (F3) as CC# 11 and is directed to the Frame Control Console (A301), at pin A of X402. 12 VDC is then directed to the Plant/Transport Mode Switch (S101), pin C. With the Plant/Transport Mode Switch in the Trans position, voltage exits the switch on pin 2 and is directed to the Machine Transport Mode Relay (K30), pin 13. The Machine Transport Relay is directed to ground by pin 14 to Pin J (X402), to Pin V (X401) and then to Pin 1 (X301). This completes the circuit, allowing current to flow energizing the relay. 12 VDC exiting the Plant/Transport Mode Switch (S101) on pin 2 is also directed to the Wing Wheels/Fold Switch (S104) on pin C. With the Wing Wheels/Fold Switch in the Fold position, voltage exits the switch on pin 1 and is directed to pin D of X402. 12 VDC is directed on the Frame Control Console Extension Harness (W301) on wire FMAIN to pin K of X401, then by a Brown wire to pin A of the Right Winglet Plunger Switch (S4) at X422. When the winglet is raised the switch is closed, allowing voltage to exit the switch at pin D. Voltage from Pin D is directed on a Brown wire to pin A of the Left Winglet Plunger Switch (S9) at X430. When the winglet is raised the switch is closed, allowing voltage to exit the switch at pin D. 12 VDC is directed from the switch on a Brown/White wire to a splice with a Red wire connected to pin A of the Fold/Unfold Solenoid (Y9) at X410. The Y9 solenoid is directed to ground from pin B by a Black wire to pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301). This completes the circuit allowing current to flow, energizing the solenoid.

With the Key Switch in the ON position, 12 VDC supplied by the tractor is directed to connector X301 (7

As electrical current exits the Wing Wheels/Fold Switch (S104) on pin 1, 12 VDC also is directed to the energized Machine Transport Mode Relay (K30) on pin 6 and exits the relay on pin 10. Voltage from pin 10 is directed to pin B of X402. 12 VDC is then directed on a FAUX wire of the Frame Control Console Extension Harness (W301), to pin C of the Frame Harness (W302) of X401. Voltage is directed by a Tan wire to a splice with a Red wire leading to pin A of the Fold/Unfold Solenoid (Y8) at X409. The Y8 solenoid is directed to ground from pin B by a Black wire to pin 1

of the 7 pin Trailer Lighting and Accessory Outlet (X301). This completes the circuit allowing current to flow, energizing the solenoid. NOTE: Planters equipped with a Drawbar Hitch require a 7 Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) and Planter Frame Extension Harness (W311) not referenced in this information. Refer to the individual Group for each harness for more information.

IF EQUIPPED WITH A DRAWBAR HITCH; • 7-Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) Connector X512 and X513 • Planter Frame Extension Harness (W311) Connector X510 and X511. IMPORTANT: Harnesses W311 and W312 are not shown on the following schematic. Refer to individual Group for each harness for diagnostic information before continuing. Hydraulic connection to tractor; • Hoses connected to correct SCV • Hoses connected to correct SCV extend/retract ports • Correct hose tips IMPORTANT: Seeding equipment harnesses are grounded to tractor and NOT the implement frame. When referencing frame ground in the following diagnostic steps, be sure there is continuity between the tractor battery negative (-) terminal and the implement frame. Once continuity is verified from battery (-) to implement frame, the implement frame may be used as frame ground to troubleshoot. Are all electrical and hydraulic connections to planter made correctly? – – –1/1

Group 15R

Marker Raise/Lower - Auto Mode Diagnostics Theory of Operation The Frame Control Console Switches operate solenoid hydraulic valves. These solenoid valves prevent a cylinder from operating unless valves are energized. The functions are selected with the corresponding switches and controlled with the tractor selective control valve(s). This machine is equipped with a left and right hand marker system. Attached to the planter frame are the Winglets. Mounted to the end of each winglet is a marker arm. At the end of each marker arm is a marker disk. As the planter is pulled through the field with one of the two markers in the unfolded position, the marker disk creates a small furrow in the soil. As the operator turns the machine around on the headland and lines up for the next pass through the field, the furrow created by the marker disk is used as a guideline for the operator to follow. The markers use their own hydraulic SCV, separate from all other planter functions. NOTE: The planter must be completely unfolded before the marker winglets and markers can operate. Marker winglets must be fully extended before markers can operate. The Automatic Marker Mode is selected by pressing the AUTO-MAN marker mode switch (S102) to the AUTO position. The Auto Marker Switch (S7), located on the planter, will control the alternating selection of right/left marker by being engaged when the planter is fully raised. When the hydraulic wheel cylinder contacts the switch in the raised position, the switch alternates between the right and left marker circuits. When the planter is fully raised again, the wheel cylinder contacts the switch again, switching it back to the original circuit, therefore alternating right and left markers. The raise and lower function is controlled by the designated SCV for extending and retracting the markers. This planter is equipped with a series of switches that prevent the operator from dropping the markers when the machine is folded and in the transport position; therefore, the planter must be

completely unfolded and winglets extended in order for the markers to operate. With the Key Switch in the RUN position, 12 VDC supplied by the tractor flows through Pin 7 of the 7 pin Trailer Lighting and Accessory Outlet (X301), exiting on a Red Wire. Current then routes through pin B of X401, into the Frame Control Console Extension Harness (W301), across Fuse (F3) exiting as cc# 11 and enters the Frame Control Console (A301) on pin A of X402. Current then flows to the Machine Transport Mode Relay (K30) enters on pin 11 and exits on pin 3, flows to the Wing Control/Marker Mode Relay (K36) enters on Pin 12 and exits on Pin 9, then enters pin 2 at the Auto/Manual Marker Mode Switch (S102). With the AUTO-MAN marker mode switch in the AUTO position, electrical current exits the switch on pin 3 and flows to pin S of X402. Current exits pin S of the Frame Control Console (A301) on the AUTO wire of the Frame Control Console Extension Harness (W301) and flows to pin R of X401. Exiting pin R, current flows on a Dark Green wire to pin T of X408 at the Auto Marker Switch (S7). Left Marker Raise/Lower: When the Auto Marker Switch (S7) is positioned to the Left Marker position, there is current flow between Pin T and Pin R of the switch. Current exits pin R of X408 on a black wire that changes to a yellow wire The Yellow Wire enters pin B of X430 at the Left Winglet Plunger Switch (S9). Since the Winglet Switch is closed in the unfolded position, 12 VDC are able to exit pin C of X430 on a Yellow/Black Wire. The Yellow/Black Wire changes to a Red wire that carries current to pin A of X462 at the Left Marker Lower Solenoid (Y3L), energizing the solenoid. The Yellow wire also carries current to Pin B of X466 at Diode Assembly #2 (DB2). Current flows through DB2 and exits on pin C of X466 and Pin C of X467.

Marker Raise/Lower - Auto Mode Diagnostics Current from Pin C of X467 exits on a Purple Wire, which changes to a Red Wire, flows to Pin A of X464 at the Left Marker Raise Solenoid (Y4L), and energizes the relay. Current from Pin C of X466 exits on a Red Wire, flows to Pin A of X463 at the Right Marker Raise Solenoid (Y4R), and energizes the relay.

240 15R 2

NOTE: Solenoid Y4R is energized so that when the left marker is raised, pressure oil is also sent to the right marker cylinder to maintain its raised position or to raise the marker if it is already lowered. Right Marker Raise/Lower: When the Auto Marker Switch (S7) is positioned to the Right Marker position, there is current flow between Pin T and Pin L of the switch. Current exits pin L of X408 on a red wire that changes to an orange wire. The Orange Wire enters pin B of X422 at Right Winglet Plunger Switch (S4). Since the Winglet Switch is closed in the unfolded position, 12 VDC are able to exit pin C of X422 on an Orange/Black Wire. The Orange/Black wire changes to a Red Wire that carries current to pin A of X461 at the Right Marker Lower Solenoid (Y3R), energizing the solenoid.

The Orange wire also carries current to Pin A of X466 at Diode Assembly #2 (DB2). Current flows through DB2 and exits on pin C of X466 and Pin C of X467. Current from Pin C of X466 exits on a Red Wire, flows to Pin A of X463 at the Right Marker Raise Solenoid (Y4R), and energizes the relay. Current from Pin C of X467 exits on a Purple Wire, which changes to a Red Wire, flows to Pin A of X464 at the Left Marker Raise Solenoid (Y4L), and energizes the relay. NOTE: Planters equipped with a Drawbar Hitch require a 7 Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) and Planter Frame Extension Harness (W311) not referenced in this information. Refer to the individual Group for each harness for more information. NOTE: Solenoid Y4L is energized so that when the right marker is raised, pressure oil is also sent to the left marker cylinder to maintain its raised position or to raise the marker if it is already lowered.

IF EQUIPPED WITH A DRAWBAR HITCH; • 7-Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) Connector X512 and X513 • Planter Frame Extension Harness (W311) Connector X510 and X511. IMPORTANT: Harnesses W311 and W312 are not shown on the following schematic. Refer to individual Group for each harness for diagnostic information before continuing. Hydraulic connection to tractor; • Hoses connected to correct SCV • Hoses connected to correct SCV extend/retract ports • Correct hose tips IMPORTANT: Seeding equipment harnesses are grounded to tractor and NOT the implement frame. When referencing frame ground in the following diagnostic steps, be sure there is continuity between the tractor battery negative (-) terminal and the implement frame. Once continuity is verified from battery (-) to implement frame, the implement frame may be used as frame ground to troubleshoot. Are all electrical and hydraulic connections to planter made correctly? – – –1/1

Group 15S

Marker Raise/Lower - Manual Mode Diagnostics Theory of Operation The Frame Control Console Switches operate solenoid hydraulic valves. These solenoid valves prevent a cylinder from operating unless valves are energized. The functions are selected with the corresponding switches and controlled with the tractor selective control valve(s). This machine is equipped with a left and right hand marker system. Attached to the planter frame are the Winglets. Mounted to the end of each winglet is a marker arm. At the end of each marker arm is a marker disk. As the planter is pulled through the field with one of the two markers in the unfolded position, the marker disk creates a small furrow in the soil. As the operator turns the machine around on the headland and lines up for the next pass through the field, the furrow created by the marker disk is used as a guideline for the operator to follow. The markers use their own hydraulic SCV, separate from all other planter functions. NOTE: The planter must be completely unfolded before the marker winglets and markers can operate. Marker winglets must be fully extended before markers can operate. The Manual Marker Mode is selected by pressing the AUTO-MAN marker mode switch (S102) to the MAN position. The selected marker on the Right/Left Marker Switch (S103) of the Frame Control Console will raise and lower each time the designated SCV for extending and retracting the markers is activated. This planter is equipped with a series of switches that prevent the operator from dropping the markers when the machine is folded and in the transport position; therefore, the planter must be completely unfolded and winglets extended in order for the markers to operate. With the Key Switch in the RUN position, 12 VDC supplied by the tractor flows through Pin 7 of the 7 pin Trailer Lighting and Accessory Outlet (X301), exiting on a Red Wire. Current then routes through pin B of X401, into the Frame Control Console Extension

Harness (W301), across Fuse (F3) exiting as cc# 11 and enters the Frame Control Console (A301) on pin A of X402. Current then flows to the Machine Transport Mode Relay (K30) enters on pin 11 and exits on pin 3, flows to the Wing Control/Marker Mode Relay (K36) enters on Pin 12 and exits on Pin 9, then enters pin 2 at the Auto/Manual Marker Mode Switch (S102). With the AUTO-MAN marker mode switch in the MAN position, electrical current exits the switch on pin 1 and flows into pin C of the Right/Left Marker Switch (S103). Left Marker Raise/Lower: When the Right/Left Marker Switch (S103) is positioned to the Left Marker detent, the left side of the switch illuminates and electrical current exits the switch on pin 2. 12 VDC then exits the Frame Control Console (A301) through pin R of X402 on cc# LMRK, travels across the Frame Control Console Extension Harness (W301), and enters pin T of X401 at the Frame Harness (W302), exiting as a Yellow Wire. The Yellow Wire enters pin B of X430 at the Left Winglet Plunger Switch (S9). Since the Winglet Switch is closed in the unfolded position, 12 VDC are able to exit pin C of X430 on a Yellow/Black Wire. The Yellow/Black Wire changes to a Red wire that carries current to pin A of X462 at the Left Marker Lower Solenoid (Y3L), energizing the solenoid. The Yellow wire also carries current to Pin B of X466 at Diode Assembly #2 (DB2). Current flows through DB2 and exits on pin C of X466 and Pin C of X467. Current from Pin C of X467 exits on a Purple Wire, which changes to a Red Wire, flows to Pin A of X464 at the Left Marker Raise Solenoid (Y4L), and energizes the relay. Current from Pin C of X466 exits on a Red Wire, flows to Pin A of X463 at the Right Marker Raise Solenoid (Y4R), and energizes the relay.

When the Right/Left Marker Switch (S103) is positioned to the Right Marker detent, the right side of the switch illuminates and electrical current exits the switch on pin 1. 12 VDC then exits the Frame Control Console (A301) through pin P of X402 on cc# RMRK, travels across the Frame Control Console Extension Harness (W301), and enters pin S of X401 at the Frame Harness (W302), exiting as an Orange Wire. The Orange Wire enters pin B of X422 at Right Winglet Plunger Switch (S4). Since the Winglet Switch is closed in the unfolded position, 12 VDC are able to exit pin C of X422 on an Orange/Black Wire. The Orange/Black wire changes to a Red Wire that carries current to pin A of X461 at the Right Marker Lower Solenoid (Y3R), energizing the solenoid.

DB2 and exits on pin C of X466 and Pin C of X467. Current from Pin C of X466 exits on a Red Wire, flows to Pin A of X463 at the Right Marker Raise Solenoid (Y4R), and energizes the relay. Current from Pin C of X467 exits on a Purple Wire, which changes to a Red Wire, flows to Pin A of X464 at the Left Marker Raise Solenoid (Y4L), and energizes the relay. NOTE: Planters equipped with a Drawbar Hitch require a 7 Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) and Planter Frame Extension Harness (W311) not referenced in this information. Refer to the individual Group for each harness for more information. NOTE: Solenoid Y4L is energized so that when the right marker is raised, pressure oil is also sent to the left marker cylinder to maintain its raised position or to raise the marker if it is already lowered.

The Orange wire also carries current to Pin A of X466 at Diode Assembly #2 (DB2). Current flows through

Marker Winglets Raise/Lower Diagnostics Theory of Operation The Frame Control Console Switches operate solenoid actuated hydraulic valves. The solenoid valve prevents a cylinder from operating unless the valve is energized. The functions are selected with the corresponding switches and controlled with the tractor selective control valve(s).

beneficial when planting near fences, around obstacles in the field, or when planting point rows.

The planter is equipped with a marker system that is attached to a winglet on each side of the planter. Each winglet is attached to the end of the planter mainframe and is used for several purposes. When the planter is in the folded position, the purpose of the winglet is to reduce the overall transport length requirement of the planter toolbar and allow ample clearance between the back of the tractor and the planter mainframe. In this mode the winglet on each end of the planter mainframe is raised, positioning the folded marker arms over the top of the planter toolbar.

NOTE: The planter must be completely unfolded before the Marker Winglets can operate. Marker Winglets must be lowered before the Markers can operate.

Another purpose of the winglet is when the planter is being prepared for field operation. In this situation each winglet can only be lowered after the planter mainframe is completely unfolded. This insures that a marker cannot be accidentally activated during the fold/unfold sequence. Once the planter mainframe is fully unfolded, the operator utilizes the Winglet Control switch on the Frame Control Console to individually lower each winglet into the planting position. The winglet must be fully lowered into the planting position before the marker associated with that winglet can be operated. During field operation, the operator can raise either winglet without interrupting planting by using the Winglet Control switch and activating the appropriate tractor SCV. When the Winglet Control switch and appropriate tractor SCV is activated, the associated marker will also raise. This feature is especially

The marker and winglet system requires the use of a tractor SCV independent from other planter hydraulic functions.

When the planter is completely unfolded, the marker winglets can be activated by: selecting either Right or Left on the Winglet Control Switch (S106), and activating the appropriate tractor SCV to either the raise or lower detent position until the winglet is fully raised/lowered. This process is then repeated for the other marker winglet (if required). With the Key Switch in the ON position, 12 VDC is supplied by the tractor is directed to X301 (7 pin Trailer Lighting and Accessory Outlet) pin 7 (Red wire) and then to pin B of X401 of the Frame Control Console Extension Harness (W301). Voltage is then directed by cc# 011A to Fuse (F3). 12 VDC from the fuse is then directed by cc# 011 to pin A (X402) of the Frame Control Console (A301). Voltage from pin A is directed to pin 11 of the Machine Transport Mode Relay (K30). 12 VDC exits the unenergized relay (K30) at pin 3. Voltage from Pin 3 is directed to pin C of the Winglet Control Switch (S106). When the Winglet Control Switch (S106) is in the center position, voltage does not exit the switch.

When the Winglet Control Switch (S106) is placed into the L (left) winglet position, 12 VDC exits the switch at pin 1 and is directed through a diode in the Frame Control Console Circuit Board to pin 1 of the Wing Control/Marker Mode Relay (K36). Voltage exits the relay at pin 16 and is directed to pin J (X402). 12 VDC is directed on cc# 010 of the Frame Control Extension Harness (W301) to pin V (X401) of the Frame Harness (W302) then on a Black wire to pin 1 (X301) of the 7 pin Trailer Lighting and Accessory Outlet. This completes the circuit allowing current to flow, energizing the Wing Control/Marker Mode Relay. When the relay is energized, 12 VDC exiting the Wing Control/Marker Mode Relay at pin 9 (available from pin 3 of the Machine Transport Mode Relay to pin 12 of the Wing Control/Marker Mode Relay) is interrupted, opening the circuit to the Auto/Manual Marker Mode Switch (S102). 12 VDC exiting the Winglet Control Switch (S106) at pin 1 is also directed to pin L (X402). Voltage is directed on the Frame Control Console Extension Harness (W301) by cc# LWNG to pin L (X401) of the Frame Harness (W302), then by a Purple/White wire to pin A (X403). 12 VDC is directed by a Black wire from X403 to the closed single throw, triple pole switch (S1) when the planter mainframe is fully unfolded. Voltage exits the switch on a White wire to pin B (X403), then directed by a Brown wire to pin B (X467) of the Diode Assembly (DB2). 12 VDC exits the Diode Assembly (DB2) at pin C (X467) as a Purple wire which is then spliced to a Red wire directed to pin A (X464) of the Left Marker Raise Solenoid (Y4L). 12 VDC from the Left Marker Raise Solenoid (Y4L) is directed to ground from pin B (X464) by a Black wire to pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301). This completes the circuit allowing current to flow, energizing the solenoid. 12 VDC exiting the closed single throw, triple pole switch (S1) at pin B (X403) on the Brown wire is also spliced to a Red wire which is directed to pin A (X460) of the Left Winglet Solenoid (Y2L). 12 VDC from the Left Winglet Solenoid (Y2L) is directed to ground from pin B (X460) by a Black wire to pin 1 of the 7 pin

Trailer Lighting and Accessory Outlet (X301). This completes the circuit allowing current to flow, energizing the solenoid. RIGHT WINGLET RAISE-LOWER When the Winglet Control Switch (S106) is placed into the R (right) winglet position, 12 VDC exits the switch at pin 2 and is directed through a diode in the Frame Control Console Circuit Board to pin 1 of the Wing Control/Marker Mode Relay (K36). Voltage exits the relay at pin 16 and is directed to pin J (X402). 12 VDC is directed on cc# 010 of the Frame Control Extension Harness (W301) to pin V (X401) of the Frame Harness (W302) then on a Black wire to pin 1 (X301) of the 7 pin Trailer Lighting and Accessory Outlet. This completes the circuit allowing current to flow, energizing the Wing Control/Marker Mode Relay. When the relay is energized, 12 VDC exiting the Wing Control/Marker Mode Relay at pin 9 (available from pin 3 of the Machine Transport Mode Relay to pin 12 of the Wing Control/Marker Mode Relay) is interrupted, opening the circuit to the Auto/Manual Marker Mode Switch (S102). 12 VDC exiting the Winglet Control Switch (S106) at pin 2 is also directed to pin H (X402). Voltage is directed on the Frame Control Console Extension Harness (W301) by cc# RWNG to pin H (X401) of the Frame Harness (W302), then on the Frame Harness (W302) by a Dark Blue wire to pin A (X404). 12 VDC is directed by a Green wire from X404 to the closed single throw, triple pole switch (S2) when the planter mainframe is fully unfolded. Voltage exits the switch on a Yellow wire to pin B (X404), then by a Gray wire to pin A (X467) of the Diode Assembly (DB2). 12 VDC exits the Diode Assembly (DB2) at pin C (X466) as a Red wire and is directed to pin A (X463) of the Right Marker Raise Solenoid (Y4R). 12 VDC from the Right Marker Raise Solenoid (Y4R) is directed to ground from pin B (X463) by a Black wire to pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301). This completes the circuit allowing current to flow, energizing the solenoid.

Pneumatic Down Force Diagnostics Theory of Operation If the planter is equipped with the Pneumatic Down Force attachment, the operator has the ability to increase and decrease down force pressure on the row units from the tractor cab (when compressor is mounted in the cab). Before planting, shop air should be used to preset the down force. The down force compressor located in the cab is used to make small, on-the-go, infield adjustments.

(3 pin Convenience Outlet) on pin 1 and enters the Pneumatic Down Force Compressor Harness (W305) as cc# 1. When the Pneumatic Down Force Compressor Motor Switch is in the ON position, 12 VDC are able to pass through the switch and into the Compressor Motor (M1), X503 on pin A, turning over the motor.

IMPORTANT: Only run compressor for 7 min. at a time. Allow the compressor to cool for 30 min. between uses.

Because the Down Force Compressor is occupying the Convenience Outlet; Switched Power, Constant Battery Power (12 VDC), and Ground are supplied by the Pneumatic Down Force Compressor Harness (W305) to a Convenience Outlet Power Extension Receptacle.

To increase system pressure (down force), turn the compressor on using the toggle switch. When the pressure gauge indicates the desired setting, turn the compressor off. To relieve system pressure, turn the valve to the left of the toggle switch, 90 degrees.

Leaks in the Pneumatic Down Force System can be diagnosed by spraying the hose connections with soapy water and repairing as necessary.

With the Key Switch in the RUN position, 12 VDC supplied by the tractor flows through connector X501

Group 15W

Transport and Wing Wheels Raise/Lower Diagnostics Theory of Operation The Frame Control Console Switches operate solenoid actuated hydraulic valves. The solenoid valve prevents a cylinder from operating unless the valve is energized. The functions are selected with the corresponding switches and controlled with the tractor selective control valves. Once the operator has completely folded the planter into the transport position and raised the tractor hitch to maximum height, it is necessary to retract the wing wheels for transportation clearance purposes. This is done by: pressing the Plant-Trans mode switch to the Trans position, holding the Wing Wheels-Fold mode switch to the Wing Wheels position, and activating the tractor SCV to the raise detent. The Left and Right Center cylinders will fully extend, raising the planter’s mainframe an extra 16.2 cm (6.3 in.). As this occurs, the Left and Right Wing Wheel cylinders retract to the transport position. In order for the planter to be safely unfolded, the wing wheels must be lowered. With the Plant-Trans mode switch in the Trans position, Wing Wheels-Fold mode switch held in the Wing Wheels position, and activating the tractor SCV to the lower detent, the Left and Right Wing Wheel cylinders will extend. As the Left and Right Wing Wheels lower, the Left and Right Center cylinders retract, lowering the mainframe 16.2 cm (6.3 in.) With the Key Switch in the ON position, 12 VDC supplied by the tractor is directed from connector X301 (7 pin Trailer Lighting and Accessory Outlet), pin 7 (Red wire). 12 VDC is available to pin B (X401) of the Frame Control Console Extension Harness (W301), and to Fuse (F3) as cc# 011A. CC# 11 enters the Frame Control Console (A301) on pin A of X402. Voltage is directed to the Plant/Transport Mode Switch

(S101), pin C. With the Plant/Transport Mode Switch in the Trans position, 12 VDC exits the switch on pin 2 and is directed to the Machine Transport Mode Relay (K30), pin 13. The Machine Transport Mode Relay (K30) is directed to ground from pin 14 to pin J (X402), on to pin V (X401), then to pin 1 (X301). This completes the circuit allowing current to flow, energizing the relay. 12 VDC exiting the Plant/Transport Mode Switch (S101) on pin 2 also enters the Wing Wheels/Fold Switch (S104) at pin C. With the Wing Wheels/Fold Switch held in the Wing Wheels position, 12 VDC exits the switch on pin 2 and the Frame Control Console (A301) through pin E of X402. 12 VDC is directed on cc TRNS. of the Frame Control Console Extension Harness (W301), and enters the Frame Harness (W302) at pin J of X401 (Light Blue wire). The Light Blue wire is directed to X445, Transport Mode Raise/Lower Relay (K34), pin 85. The Transport Mode Raise/Lower Relay (K34) is directed to ground from pin 86 (X445) to pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301). This completes the circuit allowing current to flow, energizing the relay. 12 VDC from X301 (7 pin Trailer Lighting and Accessory Outlet) pin 1 (Red wire) is available to the (K34) Transport Mode Raise/Lower Relay, Pin 30. With the relay energized, 12 VDC exits on pin 87 on a Dark Green wire. The Dark Green wire is spliced to a Red wire which goes to pin A of all of the Transport Mode Raise/Lower Solenoids (Y22, Y23, Y24, Y25). The Transport Mode Raise/Lower Solenoids (Y22, Y23, Y24, Y25) are directed to ground from pin B of each solenoid by a Black wire to pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301). This completes the circuit allowing current to flow, energizing each solenoid.

As 12 VDC exits the Wing Wheels/Fold Switch (S104) on pin 2, voltage also enters the energized Machine Transport Mode Relay (K30) at pin 5 and exits on pin 9. 12 VDC then exits the Frame Control Console (A301), pin C of X402 on cc# Y1 of the Frame Control Console Extension Harness (W301), and enters the Frame Harness (W302) on pin N of X401 (Pink wire). The Pink wire is spliced to a Red wire connected to pin A of X411 at the Center Frame, Field Raise/Lower, and Trans. Raise/Lower Solenoid (Y1). The Center Frame, Field Raise/Lower, Trans Raise/Lower Solenoid is directed to ground from pin B (X411) by a

Black wire to pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301). This completes the circuit allowing current to flow, energizing each solenoid. NOTE: Planters equipped with a Drawbar Hitch require a 7 Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) and Planter Frame Extension Harness (W311) not referenced in this information. Refer to the individual Group for each harness for more information.

Transport and Wing Wheels Raise/Lower Diagnostics with CCS Theory of Operation The Frame Control Console Switches operate solenoid actuated hydraulic valves. The solenoid valve prevents a cylinder from operating unless the valve is energized. The functions are selected with the corresponding switches and controlled with the tractor selective control valve(s). Once the operator has completely folded the planter into the transport position and raised the tractor hitch to maximum height, it is necessary to retract the wing wheels for transportation clearance purposes. This is done by: selecting Plant-Clean Out mode on the CCS Clean Out Switch (located near the Vacuum Gauge on the planter), pressing the Plant-Trans mode switch to the Trans position, holding the Wing Wheels-Fold mode switch to the Wing Wheels position, and activating the tractor SCV to the raise detent. The Left and Right Center cylinders will then fully extend, raising the planter’s mainframe an extra 6.3 inches (16.2 cm). As this occurs, the Left and Right Wing Wheel cylinders retract to the transport position. In order for the planter to be safely unfolded, the wing wheels must be lowered. With the Plant-Clean Out mode selected (S8), the Plant-Trans mode switch in the Trans position (S101), the Wing Wheels-Fold mode switch held in the Wing Wheels position, and activating the tractor SCV to the lower detent, the Left and Right Wing Wheel cylinders will extend. As the Left and Right Wing Wheels lower, the Left and Right Center cylinders retract, lowering the mainframe 6.3” (16.2 cm). With the Key Switch in the ON position, 12 VDC supplied by the tractor is directed to connector X301 (7 pin Trailer Lighting and Accessory Outlet), pin 7 (Red wire). 12 VDC is available to pin B of X401, of the Frame Control Console Extension Harness (W301),

and to Fuse (F3) as cc# 011A. CC# 011 enters the Frame Control Console (A301) on pin A of X402. Voltage then is directed to the Plant/Transport Mode Switch (S101), pin C. With the Plant/Transport Mode Switch in the Trans position, 12 VDC exits the switch on pin 2 and is directed to the Machine Transport Mode Relay (K30), pin 13. The Machine Transport Mode Relay (K30) is directed to ground from pin 14 to pin J (X402), to pin V (X401), then to pin 1 (X301), energizing the relay. 12 VDC exiting the Plant/Transport Mode Switch (S101) on pin 2 also enters the Wing Wheels/Fold Switch (S104) at pin C. With the Wing Wheels/Fold Switch held in the Wing Wheels position, 12 VDC exits the switch on pin 2 and the Frame Control Console (A301) through pin E of X402. 12 VDC is directed on cc TRNS. of the Frame Control Console Extension Harness (W301), and enters the Frame Harness (W302) on pin J of X401 (Light Blue wire). The Light Blue wire is directed to X445, Transport Mode Raise/Lower Relay (K34) pin 85. The Transport Mode Raise/Lower Relay (K34) is directed to ground from pin 86 to pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301), energizing the relay. 12 VDC from X301 (7 pin Trailer Lighting and Accessory Outlet) pin 1 (Red wire) is available to the (K34) Transport Mode Raise/Lower Relay, Pin 30. With the relay energized, 12 VDC exits on pin 87 on a Dark Green wire. The Dark Green wire is spliced to a Red wire which goes to pin A of all of the Transport Mode Raise/Lower Solenoids (Y22, Y23, Y24, Y25). The Transport Mode Raise/Lower Solenoids (Y22, Y23, Y24, Y25) are directed to ground from pin B of each solenoid by a Black wire to pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301), energizing each solenoid.

As 12 VDC exits the Wing Wheels/Fold Switch (S104) on pin 2, voltage also enters the energized Machine Transport Mode Relay (K30) on pin 5 and exits on pin 9. 12 VDC then exits the Frame Control Console (A301), pin C of X402 on cc# Y1 of the Frame Control Console Extension Harness (W301), and enters the Frame Harness (W302) on pin N of X401 (Pink wire). The Pink wire is connected to the Clean Out Mode Relay (K32), pin 30. 12 VDC is directed through the relay and exits on pin 87a as a Pink/Black wire. The Pink/Black wire is spliced to a Red wire connected to pin A of X411 at the Center Frame, Field Raise/Lower, and Trans. Raise/Lower Solenoid (Y1). The Center Frame, Field Raise/Lower, Trans Raise/Lower Solenoid is directed to ground from pin B (X411) by a Black wire to pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301), energizing the solenoid. Y1 solenoid must be energized for the planter to raise and lower in the Transport mode. Clean Out Mode: A clean out mode is provided to allow the operator the ease to clean out the hoppers while the machine is in the raised position. The raise/lower function of the planter is disabled when the operator is in the Purge Hoses mode. Since it is necessary to run the CCS Fan to purge all the hoses in the Purge Hoses mode, the operator is required to move the tractor SCV lever to the lower detent position.

12 VDC from the 7 pin Trailer Lighting and Accessory Outlet (X301), pin 7 is directed by a Red wire to pin A (X431) of the CCS Clean Out Switch (S8). If the CCS Clean Out Switch (S8) is in the Purge Hoses position (switch closed), 12 VDC is directed by a Black wire to a splice with a Black/Green wire, then to X437, pin 85 of the Clean Out Mode Relay (K32). The Clean Out Mode Relay (K32) is directed to ground by pin 86 to pin 1 of the 7 pin Trailer Lighting and Accessory Outlet (X301), energizing the relay. When the relay is activated, the circuit is opened to the Center Frame, Field Raise/Lower and Transport Raise/Lower Solenoid (Y1). With the Y1 solenoid de-energized, the operator is not able to raise or lower the planter. This permits the operator to place the raise/lower tractor SCV into the lower detent position so that the CCS fan motor can operate, yet not allow the planter to lower for proper planter clean out. NOTE: Planters equipped with a Drawbar Hitch require a 7 Pin Trailer Lighting and Accessory Outlet Extension Harness (W312) and Planter Frame Extension Harness (W311) not referenced in this information. Refer to the individual Group for each harness for more information.

General Information

CAUTION: Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic or other lines. Tighten all lines before applying pressure. Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids. If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury should reference a knowledgeable medical source. Such information is available from Deere & Company Medical Department in Moline, Illinois, U.S.A..

270 05 3

Testing Precautions IMPORTANT: TESTING PRECAUTIONS—Serious damage can result to the component or to the entire hydraulic system if lines or hoses are not connected properly. When disconnecting a line or hose from a hydraulic component, always mark the line or hose and the port from which it was removed so it can be reconnected to the proper port. Use two wrenches when attaching a hose or line to a fitting to avoid excessive twisting. Check the entire length of the lines and hoses to be certain they are not rubbing on moving parts or vibrating because of loose clamps. CLEANLINESS—If the hydraulic system should be disconnected for service, protect the ends of the hoses, tubing and ports of components from contamination with clean, lint-free towels or clean plastic bags. Before installing any replacement hose, flush the inside with unused diesel fuel or unused petroleum cleaning solvent for 10 seconds minimum. Do not use water, water soluble cleaners or compressed air. Continued on next page

6. Check hydraulic oil for milky, dirty, or discolored conditions. Smell the oil. A distinctive burned odor indicates presence of excessive heat that can destroy the oil’s lubricating qualities. Determine the conditions cause, correct it, and change the oil. 7. Check for a plugged or damaged hydraulic oil filter. A failed filter permits contaminants to circulate in the system, affecting system operation and tests. If filter is plugged, an examination of the contaminant may indicate what caused the failure.

Preliminary Checks Use the following steps for locating malfunctions in the fan hydraulics system. Many hydraulic system failures can be located by making preliminary checks of the system operation. No special tools are required to make these preliminary checks. Repair obvious failures before making further tests.

8. Check machine maintenance records to determine if the recommended service procedures have been performed and at the correct intervals. Note previous reports of unusual, frequent, or similar failures 9. If possible, operate machine. Activate all hydraulic functions and be alert for conditions that could isolate the problem. Also be alert for conditions that could cause further damage. Be prepared to stop the engine immediately.

1. Become acquainted with the hydraulic system and its components. Read the latest SERVICE INFORMATION BULLETINS. 2. If possible, talk with the operator about how the machine was performing when it failed. 3. With engine stopped, check for evidence of external oil leakage around oil seals, gaskets, or hydraulic line connections. Check for pinched or kinked lines and hoses that could restrict oil flow and cause oil to heat. 4. Check for broken drives, broken or binding linkages, or other mechanical failures.

CAUTION: Keep hands away from moving parts. Stop engine before checking hydraulic or hydrostatic lines near moving parts. 10. With engine operating, check for external and internal leaks. With all hydraulic functions in neutral, check function component return lines and housings for heating. If component control valves are leaking, return lines will be hot. 11. If these preliminary checks have failed to isolate the hydraulic problem, list all possible causes for the failure, then proceed to "DIAGNOSE MALFUNCTIONS" in the applicable group.

5. Check hydraulic oil level and determine type of oil used.

CCS Auxiliary Hydraulic Coupler Diagnostics Theory of Operation The Auxiliary Hydraulic Couplers optional kit can be installed on a CCS planter to allow the operator to use a hydraulic orbital motor for attachments at the rear of the planter such as a fill auger or conveyer to fill the CCS system with seed. The operator would plug in the hydraulic hoses of the fill system into the hydraulic couplers and activate the tractor SCV that controls the CCS Seed Delivery System Fan. With the planter lowered, the operator would then move the hydraulic Selector Valve (V30) lever to direct oil to the orbital motor of the fill system. The Auxiliary Hydraulics CCS Fan Switch (S12) at the at the rear of the planter would then be moved to the Off position to shut off oil flow to the CCS Seed Delivery Fan Solenoid (Y14), causing oil to flow to the

auxiliary couplers, through the attachment, and back to the tractor SCV. Oil returning from the attachment is directed through a Filter (J1) prior to being returned to the tractor SCV. If the oil supply from the auxiliary couplers needs to be interrupted (such as to move the auger or conveyor), the operator can move the hydraulic selector valve to stop flow from the auxiliary couplers. Once the auxiliary operation is completed, the hydraulic Selector Valve (V30) must be moved to the shut off position to allow the auxiliary system hoses to be unhooked from the couplers. The operator must also place the Auxiliary Hydraulics CCS Fan Switch (S12) to the On position to permit normal CCS Seed Delivery Fan operation.

Group 15B

CCS Seed Delivery Fan Motor Diagnostics Theory of Operation Plant Mode: With the CCS Seed Delivery System, a hydraulically driven fan provides airflow for seed delivery from a central tank to a hopper on the row unit. The CCS Seed Delivery acts as a tender for the row units. It provides a small pool of seed to each row unit at all times to supply the needs of the meter. Singulation of the seed is still handled by a meter at the row unit to maintain consistent and accurate seed spacing. In order for the CCS Seed Delivery Fan to turn, the Plant-Clean Out mode on the CCS Clean Out Switch located near the Vacuum Gauge on the planter must be selected, and the planter must be completely unfolded and lowered to the ground. Also, the tractor’s SCV associated with the Field Raise/Lower circuit must be in the lower detent and supplying adequate continuous hydraulic flow.

Case (G4) where oil can pass through the energized CCS Hydraulic Fan Motor Solenoid Valve (Y14). Oil is then directed to the CCS Fixed Displacement Hydraulic Fan Motor (M2). After the oil exits the CCS Seed Delivery Fan Motor, it is directed through the CCS Hydraulic Oil Cooler (H1) and open One Way Check Valve (D14) before re-entering the tractor on (V1A). Any CCS Seed Delivery Fan Motor seal leakage is directed through the motor case drain line to the tractor Case Drain Motor Coupler V3A. IMPORTANT: The CCS Seed Delivery Fan Motor (M2) case drain line must be connected to the tractor Case Drain Motor Coupler prior to activating a tractor SCV or motor seal damage will result.

Purge Hoses Mode For CCS hoper clean out purposes, the CCS Seed Delivery Fan can be turned on while the Planter is fully raised. This is done by selecting the Purge Hoses mode on the CCS Clean Out Switch, located near the Vacuum Gauge on the planter, and positioning the tractors SCV associated with the Field Raise/Lower circuit to the lower detented position. This supplies continuous hydraulic flow to the CCS Seed Delivery Fan without lowering the planter. With the Key Switch in the ON position, 12 VDC supplied by the tractor energizes the CCS Seed Delivery Fan Hydraulic Motor Solenoid (Y14), energizing the solenoid. If the tractors SCV associated with the Field Raise/Lower circuit is in the lower detented position and supplying continuous hydraulic flow, the fan is able to turn. Oil supplied from the tractor SCV (V2A) is directed to the Flow Control Valve (V22) and then to the CCS Seed Delivery Fan Motor

When the planter is raised (such as at the end of the field), the CCS Push Button Shut Off Switch (Row Unit) opens, interrupting the 12 VDC supply to the CCS Seed Delivery Fan Hydraulic Motor Solenoid (Y14) and oil supplied by the tractor SCV to port V2A is also stopped. Since the CCS Fixed Displacement Hydraulic Fan Motor (M2) is turning at high speed, the motor must be allowed to coast to a stop. The CCS fan impeller momentum causes the motor to continue to turn. Since the supply from the CCS Hydraulic Fan Motor Solenoid (Y14) is blocked, the check valve located in the motor opens to allow oil to loop back into the inlet of the motor. When the planter is being raised, oil is being supplied from the tractor SCV through V1A. The One Way Check Valve Kit (D14) then seats to prevent oil from entering and possibly damaging the CCS Hydraulic Oil Cooler (H1).

Group 15C

Drawbar Hitch/Independent Marker Diagnostics Theory of Operation The optional Drawbar Hitch is available to allow the planter to hitched to the tractor drawbar instead of the 3 point hitch. This allows the machine to be operated on a tractor without a rockshaft. The Drawbar Hitch is used in place of the rockshaft on a tractor to raise and lower the planter hitch, allowing the operator to unlatch or latch the wings of the planter during folding and unfolding operations. The Drawbar Hitch also increases the height of the tongue of the planter during transport. The Drawbar Hitch hydraulic system is shared with the Independent Marker system which is controlled from a independent control console in the tractor cab. The same tractor SCV is used for either function. A separate tractor SCV is used for other planter functions. When the operator selects the Drawbar Hitch function from the independent console, Solenoids Y26 and Y27 are energized. When Drawbar Hitch Solenoid Valve #2 (Y27) is energized, oil flow is blocked to and from the Marker circuit. This allows oil from the tractor SCV (V1B) , when activated to raise the planter tongue, to

be directed to Hydraulic Valve Block (G5) port TV1B and through Drawbar Hitch Solenoid Valve #1 (Y26) to exit at port DP. Oil is then directed through Fixed Orifice (O9) and into the base end of the Drawbar Hitch Cylinder (C17). Return oil from the Drawbar Hitch Cylinder is directed to port DR, through the Hydraulic Valve Block (G5) to exit at port TV2B then back to the tractor SCV coupler (V2B). When the tractor SCV is activated to lower the planter tongue, oil is directed to Hydraulic Valve Block (G5) port TV2B and through the valve to port DR. Oil is then directed to the rod end of the Drawbar Hitch Cylinder (C17). Return oil from the base end of the Drawbar Hitch Cylinder is directed through Fixed Orifice (O9) to port DP of Hydraulic Valve Block (G5). Oil is then directed through the Drawbar Hitch Solenoid Valve #1 to exit at port TV1B, then back to the tractor SCV coupler (V1B). When the operator selects the Marker function, Solenoids Y26 or Y27 are not energized. This isolates the Drawbar Hitch Cylinder from the Marker circuit and allows the Markers to function.

Group 15D

Field Raise/Lower Diagnostics Theory of Operation Field Raise Lower: The Frame Control Console Switches operate solenoid hydraulic valves. The solenoid valve prevents a cylinder from operating unless the valve is energized. The functions are selected with the corresponding switches and controlled with the tractor selective control valve(s). The operator can raise and lower the planter when it is unfolded and in the field position by pressing the Plant-Trans mode switch to the Plant position and activating the appropriate tractor SCV. Each time the planter is lowered, the unfold circuit is charged and the Center Lift and Wing Wheel Cylinders rephase themselves. This is to insure that the planter main frame remains level side to side and the fold cylinders maintain the fully extended position to keep the main frame straight. When the Plant/Transport Mode Switch is in the Plant Position and appropriate electrical conditions have been met, the following solenoids to be energized: Fold/Unfold Solenoid (Y8), Center Frame, Field Raise/Lower, and Trans. Raise/Lower Solenoid (Y1), Plant Mode Raise/Lower Solenoid #1 (Y18), Plant Mode Raise/Lower Solenoid #2 (Y19), Plant Mode Raise/Lower Solenoid #3 (Y20), Plant Mode Raise/Lower Solenoid #4 (Y21). Planter Raising: As the planter is raising, oil supplied from the Tractor SCV (V1A) is directed to the Hydraulic Valve Block (G1) port V1A, and through the Field Raise/Lower and Transport Raise/Lower Solenoid Valve (Y1) to the Flow

Divider Valve/Combiner (F1). Flow is split proportionally by the Flow Divider/Combiner to the left and right side of the planter frame. Planter Raising-Left Side: Oil supplied from the Flow Divider/Combiner to the left side of the planter is directed through the Left Counter Balance Valves (6A). Oil supplied from the Left Counter Balance Valve (6A) exits at port CLP1 to the base end of the Left Center Lift Cylinders (C3, C4). The oil exiting the rod side of the Left Center Lift Cylinders (C3, C4) is directed back into Hydraulic Valve Block (G1) at port CLR1, through the open Left Pilot Operated Lock Valve (21C) and Plant Mode Raise Lower Solenoid #1 (Y18) to port LWP. Oil is then directed to the Hydraulic Valve Block (G2) at port LRWP. Oil from port LRWP is directed through the valve block and exits at port WCP to the base end of the Left Wing Wheel Cylinder (C1), and through an adjacent port WCP to the base end of the Left Wing Wheel Cylinder (C2). Oil returning from the rod end of the Left Wing Wheel Cylinder (C1) is directed to port WCR. Oil returning from the rod end of the Left Wing Wheel Cylinder (C2) is directed to an adjacent port WCR. The combined return flow from the rod side of the Left Wing Wheel Cylinders (C1, C2) exits the Hydraulic Valve Block (G2) at port LRWR and is directed to port LWR of Hydraulic Valve Block (G1). Oil is directed through the Plant Mode Raise Lower Solenoid #2 (Y19) and joins flow returning from the right side of the planter to exit the valve block at port V2A before returning to the tractor SCV coupler V2A.

Oil supplied from the Flow Divider/Combiner to the right side of the planter is directed through the Right Counter Balance Valves (6B). Oil supplied from the Right Counter Balance Valve (6B) exits at port CLP2 to the base end of the Right Center Lift Cylinders (C5, C6). The oil exiting the rod side of the Right Center Lift Cylinders (C5, C6) is directed back into Hydraulic Valve Block (G1) at port CLR2, through the open Right Pilot Operated Lock Valve (21D) and Plant Mode Raise Lower Solenoid #3 (Y20) to port RWP. Oil is then directed to the Hydraulic Valve Block (G3) at port LRWP. Oil from port LRWP is directed through the valve block and exits at port WCP to the base end of the Right Wing Wheel Cylinder (C7), and through an adjacent port WCP to the base end of the Right Wing Wheel Cylinder (C8). Oil returning from the rod end of the Right Wing Wheel Cylinder (C7) is directed to port WCR. Oil returning from the rod end of the Right Wing Wheel Cylinder (C8) is directed to an adjacent port WCR. The combined return flow from the rod side of the Right Wing Wheel Cylinders (C7, C8) exits the Hydraulic Valve Block (G3) at port LRWR and is directed to port RWR of Hydraulic Valve Block (G1). Oil is directed through the Plant Mode Raise Lower Solenoid #4 (Y21) and joins flow returning from the left side of the planter to exit the valve block at port V2A before returning to the tractor SCV coupler V2A. Planter Raised When the planter is raised and the appropriate tractor SCV is in neutral, the Left Counter Balance Valve (6A) and Right Counter Balance Valve (6B) are seated to block flow from exiting the Center Lift Cylinders (C3, C4, C5, C6). Pressure relief in the left and right Center Lift Cylinders is limited to 3500 psi by the Counter Balance Valves. Pressure in the left and right Wing Wheel Cylinders (C1, C2, C7, C8) are monitored through Sense Check Kits (9A, 9B, 9C, 9D) to both the 4500 psi Pressure Relief Valve (V25) and 6000 psi Pressure Relief Valve (V24). Planter Lowering: As the planter is lowering, oil supplied from the Tractor SCV (V2A) is directed to Hydraulic Valve Block (G1)

port V2A. Oil is directed through the un-energized Fold Unfold Solenoid (Y9) to port LFP to the base end of the Left Fold Unfold Cylinder (C9) and to port RFP to the base end of the Right Fold Unfold Cylinder (C10). Any oil displaced from the rod ends to fully extend the Left and Right Fold Unfold Cylinders is directed to port LFR and RFR of the Hydraulic Valve Block (G1) and then through the energized Fold Unfold Solenoid (Y8). Oil is directed from port V1A to the tractor SCV Coupler V1A. Planter Lowering-Left Side As the planter is lowering, oil supplied from the Tractor SCV (V2A) is also directed in Hydraulic Valve Block (G1) through the Plant Mode Raise Lower Solenoid #2 (Y19) and exits the valve block at port LWR. Oil is then directed to port LRWR of the Hydraulic Valve Block (G2). Oil is directed through the valve block and exits at port WCR to the rod end of the Left Wing Wheel Cylinder (C1), and through an adjacent port WCR to the rod end of the Left Wing Wheel Cylinder (C2). Oil returning from the base end of the Left Wing Wheel Cylinder (C1) is directed to port WCP. Oil returning from the base end of the Left Wing Wheel Cylinder (C2) is directed to an adjacent port WCP. The combined return flow from the piston side of the Left Wing Wheel Cylinders (C1, C2) exits the Hydraulic Valve Block (G2) at port LRWP and is directed to port LWP of Hydraulic Valve Block (G1). Oil is then directed through the Plant Mode Raise Lower Solenoid #1 (Y18) to the Left Pilot Operated Lock Valve (21C) forcing it open, then to port CLR1, and on to the rod end of the Center Lift Cylinders (C3, C4). A pressure signal from the supply to the rod end of Left Wing Wheel Cylinders is utilized to signal the Left Counter Balance Valve (6A) to open. If sufficient signal pressure is present, the Left Counter Balance Valve (6A) opens and directs oil to the Flow Divider Combiner Valve (F1). Oil from the left and right sides of the planter are metered together in the Flow Divider Combiner Valve (F1) and then directed through the Field Raise Lower Solenoid Valve (Y1). Oil exiting the Field Raise Lower Solenoid Valve (Y1) is directed to port V1A and on to the tractor SCV coupler V1A.

Field Raise/Lower Diagnostics If the Left Wing Wheel Cylinders (C1, C2) are fully retracted prior to the Center Lift Cylinders (C3, C4), the Left Wing Wheel Cylinder Rephasing Valve (V10) will open when 1600 psi differential pressure is obtained between the rod end and base end of the Left Wing Wheel Cylinders. When the Left Wing Wheel Cylinder Rephasing Valve (V10) is open, oil can bypass the Left Wing Wheel Cylinders (C1, C2) and be directed to the rod end of the left Center Lift Cylinders (C3, C4) so they can fully retract. If the left Center Lift Cylinders (C3, C4) are fully retracted prior to the Left Wing Wheel Cylinders (C1, C2), the Left Center Lift Cylinder Rephasing Valve (5A) will open when 1600 psi differential pressure is obtained between the rod end and base end of the left Center Lift Cylinders (C3, C4). When the left Center Lift Cylinder Rephasing Valve (5A) is open, oil can bypass the rod end of the Center Lift Cylinders (C3, C4) so the Left Wing Wheel Cylinders (C1, C2) can fully retract. Planter Lowering-Right Side As the planter is lowering, oil supplied from the Tractor SCV (V2A) is also directed in Hydraulic Valve Block (G1) through the Plant Mode Raise Lower Solenoid #4 (Y21) and exits the valve block at port RWR. Oil is then directed to port LRWR of the Hydraulic Valve Block (G3). Oil is directed through the valve block and exits at port WCR to the rod end of the Right Wing Wheel Cylinder (C7), and through an adjacent port WCR to the rod end of the Right Wing Wheel Cylinder (C8). Oil returning from the base end of the Right Wing Wheel Cylinder (C7) is directed to port WCP. Oil returning from the base end of the Right Wing Wheel Cylinder (C8) is directed to an adjacent port WCP. The combined return flow from the piston side of the Right Wing Wheel Cylinders (C7, C8) exits the Hydraulic Valve Block (G3) at port LRWP and is directed to port RWP of Hydraulic Valve Block (G1). Oil is then directed through the Plant Mode Raise Lower Solenoid

#3 (Y20) to the Right Pilot Operated Lock Valve (21C) forcing it open, then to port CLR2, and on to the rod end of the Center Lift Cylinders (C5, C6). A pressure signal from the supply to the rod end of Left Wing Wheel Cylinders is utilized to signal the Right Counter Balance Valve (6B) to open. If sufficient signal pressure is present, the Right Counter Balance Valve (6B) opens and directs oil to the Flow Divider Combiner Valve (F1). Oil from the left and right sides of the planter are metered together in the Flow Divider Combiner Valve (F1) and then directed through the Field Raise Lower Solenoid Valve (Y1). Oil exiting the Field Raise Lower Solenoid Valve (Y1) is directed to port V1A and on to the tractor SCV coupler V1A. If the Right Wing Wheel Cylinders (C7, C8) are fully retracted prior to the Center Lift Cylinders (C5, C6), the Right Wing Wheel Cylinder Rephasing Valve (V23) will open when 1600 psi differential pressure is obtained between the rod end and base end of the Right Wing Wheel Cylinders. When the Right Wing Wheel Cylinder Rephasing Valve (V23) is open, oil can bypass the Right Wing Wheel Cylinders (C7, C8) and be directed to the rod end of the right Center Lift Cylinders (C5, C6) so they can fully retract. If the right Center Lift Cylinders (C5, C6) are fully retracted prior to the Right Wing Wheel Cylinders (C7, C8), the Right Center Lift Cylinder Rephasing Valve (5B) will open when 1600 psi differential pressure is obtained between the rod end and base end of the right Center Lift Cylinders (C5, C6). When the Right Center Lift Cylinder Rephasing Valve (5B) is open, oil can bypass the rod end of the Center Lift Cylinders (C5, C6) so the Right Wing Wheel Cylinders (C7, C8) can fully retract. NOTE: Refer to port labeling on Hydraulic Valve Blocks (G1, G2, G3) when verifying circuit operation, component location, and diagnostic procedures.

Hydraulic Power Diagnostics Theory of Operation Hydraulic power is supplied to the Planter’s Hydraulic Valve (G1) and the C.C.S. Fan Motor through a single set of SCV’s from the tractor. The two SCV’s from the tractor consist of; • Tractor SCV Extend Circuit - V1A • Tractor SCV Return Circuit - V2A If the Planter uses an independent or a Stand-Alone set of SCV’s to operate the markers, the secondary set of SCV’s consist of;

• Tractor SCV Return Circuit - V2B With the tractor running, the appropriate SCV Lever/Switch in the raise or lower detent position, and the SCV’s set at maximum flow, the Tractor SCV Extend and Retract Circuits - (V1A, V2A, V1B, and V2B) provide hydraulic flow and pressure to the Hydraulic Valve G1. When a particular function of the Planter is activated, the Hydraulic Valve (G1) distributes oil through the correct solenoid actuated hydraulic valve(s).

Group 15F

Machine Fold/Unfold Diagnostics Theory of Operation The Frame Control Console Switches operate solenoid actuated hydraulic valves. The solenoid valve prevents a cylinder from operating unless the valve is energized. The functions are selected with the corresponding switches and controlled with the tractor selective control valve(s). For ease of transportation, the planter’s wings fold forward to the transport position and the machine is towed like a two-wheeled cart behind the tractor. The machine is folded by: pressing the Plant-Trans mode switch to the Trans position, holding the Wing Wheels-Fold mode switch to the Fold mode position, and activating the SCV until the machine is folded. Once folded, the tractor’s three point hitch is raised to engage the wing frame latch hooks. After the wings are latched, the tractor’s three point hitch is fully raised and the wing wheels are fully retracted. IMPORTANT: Do not fully raise the tractor’s three point hitch while folding or unfolding. Structural damage to machine may result.

Machine Fold: As the planter is folded to the transport position, oil supplied from the tractor SCV (V1A) is directed into Hydraulic Valve Block (G1) through port V1A to the Fold/Unfold Solenoid Valve (Y8). Hydraulic oil exits the Hydraulic Valve Block (G1) at ports LFR and RFR to the rod side of both the Left and Right Fold/Unfold Cylinders (C9 and C10). As the cylinders retract, the planter wings fold forward. The oil from the base end of the Fold/Unfold Cylinders (C9 and C10) is directed back into Hydraulic Valve Block (G1) through ports LFP and RFP to the Fold/Unfold Solenoid Valve (Y9) before exiting the valve block at port V2A and re-entering the tractor at SCV (V2A). Pressure in the rod end of the cylinder is monitored through a Sense Check Kit (9F) to both the 4500 psi Pressure Relief Valve (V25) and 6000 psi Pressure Relief Valve (V24). Machine Unfold:

The machine is unfolded by: lowering the wing wheels, lowering the tractor’s three point hitch until the hitch tube is below the wing latch hooks, unlatching the wings, pressing the Plant-Trans Mode Switch to the Trans position, holding the Wing Wheels-Fold Mode Switch to the Fold mode position, and activating the SCV until the machine is completely unfolded.

As the planter is unfolded to the field position, oil supplied from the tractor SCV (V2A) is directed into Hydraulic Valve Block (G1), through port V2A to the Fold/Unfold Solenoid Valve (Y9). Hydraulic oil exits the Hydraulic Valve Block (G1) at ports LFP and RFP to the base end of both the Left and Right Fold/Unfold Cylinders (C9 and C10). As the cylinders extend, the planter wings unfold rearward. The oil from the rod end of the Fold/Unfold Cylinders (C9 and C10) is directed back into Hydraulic Valve Block (G1) through ports LFR and RFR to the Fold/Unfold Solenoid Valve (Y8) before exiting the valve block at port V1A and re-entering the tractor at SCV (V1A).

When the Plant-Trans Mode Switch (S101) is in the Trans Position and the Wing Wheels-Fold Mode Switch (S104) is held in the Fold mode position, the two Fold/Unfold Solenoids (Y8, Y9) are energized.

Pressure in the base end of the cylinder is monitored through a Sense Check Kit (9E) to both the 4500 psi Pressure Relief Valve (V25) and 6000 psi Pressure Relief Valve (V24).

NOTE: It may be necessary to lower the tractor’s three point hitch so the wing latch hooks will clear the hitch tube when folding and unfolding.

Group 15G

Marker Raise/Lower - Stand Alone SCV Diagnostics Theory of Operation The Frame Control Console Switches operate solenoid hydraulic valves. These solenoid valves prevent a cylinder from operating unless valves are energized. The functions are selected with the corresponding switches and controlled with the tractor selective control valve(s). This machine is equipped with a left and right hand marker system. Attached to the planter frame are the Winglets. Mounted to the end of each winglet is a marker arm. At the end of each marker arm is a marker disk. As the planter is pulled through the field with one of the two markers in the unfolded position, the marker disk creates a small furrow in the soil. As the operator turns the machine around on the headland and lines up for the next pass through the field, the furrow created by the marker disk is used as a guide line for the operator to follow. The markers use their own tractor SCV, separate from all other planter functions. NOTE: This planter is equipped with a series of switches that prevent the operator from dropping the markers when the machine is folded and in the transport position. The planter must be completely unfolded before the marker winglets and markers can operate. Marker winglets must be fully extended before markers can operate. Because this planter is equipped with an Auto Marker Switch (Dimmer Switch), the markers have the ability to alternately raise and lower each time the Stand Alone SCV is raised and lowered. In order for the AUTO Marker Mode to function, the AUTO-MAN Marker Mode Switch must be in the AUTO position and the TRANS-PLANT Mode Switch must be in the PLANT position. The markers can also be controlled manually by selecting the MAN position of the AUTO-MAN Marker

TM2129 (01MAY04)

Mode Switch and either R or L on the RIGHT-LEFT Marker Select Switch. The TRANS-PLANT Mode Switch must be in the PLANT position. Left Marker Raise/Lower - AUTO Mode: When the Auto Marker Switch – Dimmer Switch (S7) is positioned so the circuit between pin B and A is closed, the Left Marker Raise Solenoid (Y4L) and Right Marker Raise Solenoid (Y4R) are energized. When and Left Winglet Plunger Switch (S9) is closed, 12 VDC is able to energize the Left Marker Lower Solenoid (Y3L). When the operator moves the tractor SCV to the raise position, oil from the SCV (V1B) is directed through the Left Marker Lower Solenoid Valve (Y3L) and Fixed Orifice (O1) before entering the Left Marker Cylinder (C11) - piston side. As the cylinder extends, the marker raises to the folded position. The oil on the rod side is forced through Fixed Orifice (O3) and the Left Marker Raise Solenoid Valve (Y4L) before re-entering the tractor through SCV (V2B). When the operator moves the tractor SCV to the lower position, oil from the SCV (V2B) is directed through Left Marker Raise Solenoid Valve (Y4L) and Fixed Orifice (03) into the Left Marker Cylinder (C11) - rod side. As the cylinder retracts, the marker is lowered. The oil on the piston side is forced through Fixed Orifice (01) and Left Marker Lower Solenoid Valve (Y3L) before re-entering the tractor through SCV (V1B). Left Marker Raise/Lower - MAN Mode: When the Right/Left Marker Switch (S103) is positioned to the Left Marker Detent, the Left Marker Raise Solenoid (Y4L) and Right Marker Raise Solenoid (Y4R) are energized. When the Left Winglet Plunger Switch (S9) is closed, 12 VDC is able to energize the Left Marker Lower Solenoid (Y3L).

When the operator moves the tractor SCV to the raise position, oil from the SCV (V1B) is directed through the Left Marker Lower Solenoid Valve (Y3L) and Fixed Orifice (O1) before entering the Left Marker Cylinder (C11) - piston side. As the cylinder extends, the marker raises to the folded position. The oil on the rod side is forced back through Fixed Orifice (O3) and Left Marker Raise Solenoid Valve (Y4L) before re-entering the tractor through SCV (V2B).

When the operator moves the tractor SCV to the lower position, oil from the SCV (V2B) is directed to the Right Marker Raise Solenoid Valve (Y4R) and through Fixed Orifice (O4) into the Right Marker Cylinder (C12) - rod side. As the cylinder retracts, the marker is lowered. The oil on the piston side is forced through Fixed Orifice (O2) and Right Marker Lower Solenoid Valve (Y3R) before re-entering the tractor through SCV (V1B).

When the operator moves the tractor SCV to the lower position, oil from the SCV (V2B) is directed through Left Marker Raise Solenoid Valve (Y4L) and Fixed Orifice (O3) into the Left Marker Cylinder (C11) - rod side.

The oil on the piston side is forced through Fixed Orifice (O1) and Left Marker Lower Solenoid Valve (Y3L) before re-entering the tractor through SCV (V1B).

Right Marker Raise/Lower - MAN Mode: When the Right/Left Marker Switch (S103) is positioned to the Right Marker Detent the Left Marker Raise Solenoid (Y4L) and Right Marker Raise Solenoid (Y4R) are energized. When the Right Winglet Plunger Switch (S4) is closed, 12 VDC is able to energize the Right Marker Lower Solenoid (Y3R).

Right Marker Raise/Lower - AUTO Mode: When the Auto Marker Switch - Dimmer Switch (S7) is positioned so the circuit between pin B and C is closed, the Left Marker Raise Solenoid (Y4L) and Right Marker Raise Solenoid (Y4R) are energized. When the Right Winglet Plunger Switch (S4) is closed, 12 VDC is able to energize the Right Marker Lower Solenoid (Y3R). When the operator moves the tractor SCV to the raise position, oil from the SCV (V1B) is directed through the Right Marker Lower Solenoid Valve (Y3R) and Fixed Orifice (O2) before entering the Right Marker Cylinder (C12) - piston side.

Marker Winglet Raise/Lower Diagnostics Theory of Operation The Frame Control Console Switches operate solenoid actuated hydraulic valves. The solenoid valve prevents a cylinder from operating unless the valve is energized. The functions are selected with the corresponding switches and controlled with the tractor selective control valve(s). The planter is equipped with a marker system that is attached to a winglet on each side of the planter. Each winglet is attached to the end of the planter mainframe and is used for several purposes. When the planter is in the folded position, the purpose of the winglet is to reduce the overall transport length requirement of the planter toolbar and allow ample clearance between the back of the tractor and the planter mainframe. In this mode the winglet on each end of the planter mainframe is raised, positioning the folded marker arms over the top of the planter toolbar. Another purpose of the winglet is when the planter is being prepared for field operation. In this situation each winglet can only be lowered after the planter mainframe is completely unfolded. This insures that a marker cannot be accidentally activated during the fold/unfold sequence. Once the planter mainframe is fully unfolded, the operator utilizes the Winglet Control switch on the Frame Control Console to individually lower each winglet into the planting position. The winglet must be fully lowered into the planting position before the marker associated with that winglet can be operated. During field operation, the operator can raise either winglet without interrupting planting by using the Winglet Control switch and activating the appropriate tractor SCV. When the Winglet Control switch and appropriate tractor SCV is activated, the associated marker will also raise. This feature is especially beneficial when planting near fences, around obstacles in the field, or when planting point rows.

NOTE: The planter must be completely unfolded before the Marker Winglets can operate. Marker Winglets must be lowered before the Markers can operate. When the planter is completely unfolded, the marker winglets can be activated by: selecting either Right or Left on the Winglet Control Switch (S106), and activating the appropriate tractor SCV to either the raise or lower detent position until the winglet is fully raised/lowered. This process is then repeated for the other marker winglet (if required). RIGHT WINGLET RAISE When the Winglet Control Switch (S106) is placed into the R (right) winglet position and the appropriate tractor SCV is activated to raise position, oil is supplied from the tractor SCV port V1B to the Hydraulic Valve Block (G1) port V1B. Oil is then directed from the Hydraulic Valve Block (G1) by port LV1B for the Left Marker (not activated) and port RV1B for the Right Marker. Oil enters the Hydraulic Valve Block (G3) at port LRV1B and is directed to the Right Winglet Solenoid Valve (Y2R). Since the Right Winglet Solenoid Valve is energized, oil is directed through the solenoid and exits the Hydraulic Valve Block (G3) at port WGP. Oil is then directed through Fixed Orifice O6 to the base end of the Right Winglet Cylinder (C16). Oil from the rod end of the cylinder (C16) is directed through Fixed Orifice O8 to port WGR of the Hydraulic Valve Block (G3) and exits the valve at port LRV2B. Oil is then directed to port RV2B of Hydraulic Valve Block (G1), through the valve block and exits at port V2B before entering the tractor SCV at port V2B.

The marker and winglet system requires the use of a tractor SCV independent from other planter hydraulic functions.

Oil is then directed from the Hydraulic Valve Block (G1) by port LV2B for the Left Marker (not activated) and port RV2B for the Right Marker

270 15H 2

Oil enters the Hydraulic Valve Block (G3) at port LRV2B and exits the valve at port WGR. Oil is then directed through Fixed Orifice O8 to the rod end of the Right Winglet Cylinder (C16). Oil from the base end of the Right Winglet Cylinder (C16) is directed through Fixed Orifice O6 to the Hydraulic Valve Block (G3) port WGP. Since the Right Winglet Solenoid Valve (Y2R) is energized, oil is directed through the solenoid and exits the Hydraulic Valve Block (G3) at port LRV1B. Oil is then directed to port RV1B of Hydraulic Valve Block (G1), through the valve block and exits at port V1B before entering the tractor SCV at port V1B. RIGHT WINGLET RELIEF PROTECTION The right winglet circuit is designed with thermal relief protection for each segment of the circuit when the winglet is in a static (stationary) position and the Right Winglet Solenoid (Y2R) is not energized. Sense Check Kits 9H, 9J are used to signal the 4500 psi Pressure Relief Valve (V25) and 6000 psi Pressure Relief Valve (V24), which are all located in the Hydraulic Valve Block (G1). If the planter is hydraulically connected to the tractor and pressure builds in excess of 4500 psi in a circuit monitored by a Sense Check Kit, the 4500 psi Pressure Relief Valve opens and relieves circuit pressure into the tractor V2A port. If the planter is not hydraulically connected to the tractor and pressure builds in excess of 6000 psi, the 6000 psi Pressure Relief Valve (V24) opens and relieves pressure to atmosphere.

Relief Valve (V27). Pressure in excess of 6000 psi is relieved to atmosphere. NOTE: Refer to port labeling on Hydraulic Valve Blocks (G1, G2, G3) when verifying circuit operation, component location and diagnostic procedures. LEFT WINGLET RAISE When the Winglet Control Switch (S106) is placed into the L (left) winglet position and the appropriate tractor SCV is activated to raise position, oil is supplied from the tractor SCV port V1B to the Hydraulic Valve Block (G1) port V1B. Oil is then directed from the Hydraulic Valve Block (G1) by port RV1B for the Right Marker (not activated) and port LV1B for the Left Marker. Oil enters the Hydraulic Valve Block (G2) at port LRV1B and is directed to the Left Winglet Solenoid Valve (Y2L). Since the Left Winglet Solenoid Valve is energized, oil is directed through the solenoid and exits the Hydraulic Valve Block (G2) at port WGP. Oil is then directed through Fixed Orifice O5 to the base end of the Left Winglet Cylinder (C15). Oil from the rod end of the cylinder (C15) is directed through Fixed Orifice O7 to port WGR of the Hydraulic Valve Block (G2) and exits the valve at port LRV2B. Oil is then directed to port LV2B of Hydraulic Valve Block (G1), through the valve block and exits at port V2B before entering the tractor SCV at port V2B. LEFT WINGLET LOWER When the Winglet Control Switch (S106) is placed into the L (left) winglet position and the appropriate tractor SCV is activated to lower position, oil is supplied from the tractor SCV port V2B to the Hydraulic Valve Block (G1) port V2B. Oil is then directed from the Hydraulic Valve Block (G1) by port RV2B for the Right Marker (not activated) and port LV2B for the Left Marker.

Group 15I

Transport Raise/Lower Diagnostics Theory of Operation The Frame Control Console Switches operate solenoid actuated hydraulic valves. The solenoid valve prevents a cylinder from operating unless the valve is energized. The functions are selected with the corresponding switches and controlled with the tractor selective control valve(s). Once the operator has completely folded the planter into the transport position and raised the tractor rockshaft to maximum height, it is necessary to raise/retract the wing wheels for transportation clearance purposes. This is done by pressing the Plant-Trans Mode Switch to the Trans position, holding the Wing Wheels-Fold Mode Switch to the Wing Wheels mode position, and activating the tractor SCV to the raise detent. The Left and Right Center Cylinders will over-extend themselves and the planter’s mainframe will raise an extra 6.3 inches (16.2 cm). As this occurs, the Left and Right Wing Wheel Cylinders retract to the transport position. In order for the planter to be safely unfolded, the wing wheels must be lowered. With the Plant-Trans Mode Switch remaining in the Trans position, Wing Wheels-Fold Mode Switch still held in the Wing Wheels mode position, and activating the tractor SCV to the lower detent, the Left and Right Wing Wheel Cylinders will extend. As the Left and Right Wing Wheels lower, the Left and Right Center Cylinders retract, lowering the mainframe to its original height. When the Plant-Trans Mode Switch (S101) is in the Trans Position and the Wing Wheels-Fold Mode Switch (S104) is held in the Wing Wheels mode position, 12VDC is directed to the Field Raise/Lower and Transport Raise/Lower Solenoid (Y1), the Transport Mode Raise/Lower Solenoid #1 (Y22), the Transport Mode Raise/Lower Solenoid #2 (Y23), the Transport Mode Raise/Lower Solenoid #3 (Y24) and the Transport Mode Raise/Lower Solenoid #4 (Y25), energizing the solenoids and opening the valves to flow.

NOTE: There are various check valves, rephasing valves, Counter Balance valves and pressure relief valves in the transport raise and lower circuit. During normal operation in transport mode, most of these valves have no affect on the hydraulic circuit. Possible problems caused by these additional valves are addressed in the Field Raise/Lower diagnostic procedure. Transport Raise: As the planter’s mainframe rises to the over-extended transport position, oil from the tractor SCV (V1A) is directed into Hydraulic Valve Block (G1) port V1A, through the Field Raise/Lower and Transport Raise/Lower Solenoid Valve (Y1), Flow Divider Valve/Combiner (F1), Left and Right Counter Balance Valves (6A and 6B), exiting through port CLP1 and CLP2 and into the Left and Right Center Lift Cylinders (C3, C4, C5 and C6) - piston side. As the cylinders extend, the center frame rises. The oil exiting the rod side of the four Center Cylinders (C3, C4, C5, and C6) is directed back into Hydraulic Valve Block (G1) through ports CLR1 and CLR2, through the open Left and Right Pilot Operated Lock Valves (21C and 21D), Left and Right Transport Mode Raise/Lower Solenoid Valves (Y23 and Y25) exiting at ports LWR and RWR to Hydraulic Valve Block (G2, G3) ports LRWR exiting at ports WCR and into the Left and Right Wing Wheel Cylinders (C1, C2, C7, and C8) – rod side. As the cylinders retract, the left and right wing wheels rise to the transport position. The oil on the piston side of the four Wing Wheel Cylinders (C1, C2, C7, C8) is directed to ports WCP through Left and Right Hydraulic Valve Block (G2 and G3) exiting at port LRWP, back into Hydraulic Valve Block (G1) at port LWP and RWP, through Left and Right Transport Mode Raise/Lower Solenoid Valves (Y22 and Y24), before exiting Hydraulic Valve Block (G1) at port V2A and re-entering the tractor through SCV (V2A).

Transport Raise/Lower Diagnostics As the planter’s mainframe lowers from the over-extended transport position, oil from the tractor SCV (V2A) is directed into Hydraulic Valve Block (G1), port V2A, through the Right and Left Transport Mode Raise/Lower Solenoid Valves (Y22 and Y24) ports LWP and RWP, to the Left and Right Hydraulic Valve Block (G2 and G3), port LRWP exiting at ports WCP into the Left and Right Wing Wheel Cylinders (C1, C2, C7, C8) - piston side. As the cylinders extend, the left and right wing wheels descend. The oil on the rod side of the four Wing Wheel Cylinders (C1, C2, C7, C8) is directed back into ports WCR of the Left and Right Hydraulic Valve Block (G2 and G3) exiting at port LRWR to port LWR and RWR of Hydraulic Valve Block

(G1), through Left and Right Transport Mode Raise/Lower Solenoid Valves (Y23 and Y25), Left and Right Pilot Operated Check Valves (21C and 21D) exiting at ports CLR1 and CLR2 and into the Left and Right Center Lift Cylinders (C3, C4, C5, C6) - rod side. As the mainframe lowers, the oil on the piston side of the four Center Cylinders (C3, C4, C5, C6) is directed back into Hydraulic Valve Block (G1) at ports CLP1 and CLP2, through the Left and Right Counter Balance Valves (6A and 6B), Flow Divider Valve/Combiner (F1), Field Raise/Lower and Transport Raise/Lower Solenoid Valve (Y1), before exiting the Hydraulic Valve Block (G1) at port V1A and re-entering the tractor through SCV (V1A).
