Thank you for purchasing this manual from Farm Manuals Fast. Your contribution will help us continue to collect and expand our manual database. Tips for getting the most out of this manual Keep this manual in a safe place! Digital files seem to have a habit of getting lost exactly when you need them most. To ensure that you don’t accidentally delete or misplace this file here are some tips you should follow: •
•
Immediately after downloading your manual (i.e. now) it’s a good idea to save this file in a place you will remember. We recommend putting it in a folder. To make a new folder in Windows just right click -> New -> Folder. Name the folder something like Digital Manuals, Tractor Manual, etc. Once you have a folder for this file, go to File -> Save As… Now save the manual file to the folder you created. If you want, rename the file to something you will remember. We recommend including the model number (this is important in case you forget where you saved this file on your computer). Remember: If you have put this file in a safe place on your computer and are unable to find it again the following year, try Windows search feature: Start ->Search. Type in the model number or another keyword that you know is in the file name.
Quick Search If you are looking for something specific in this manual, you are in luck; All our manuals are searchable! Just press CTR + F and type in what you are looking for. Some things to remember when using the quick search feature: •
•
Your search won’t be 100 percent accurate. The software we use to make the text readable might confuse an “I” with an “l” (L and I ) or a smudge on the paper might have made the text unreadable by the software. Quick search will only search the exact words you type into the search bar in the exact order you put them in. For example if you type in 20 millimeters when in the manual it was written 20 mm your search will not work.
What you should get from this tip is that: Quick Search is not completely reliable. Be sure to check the index and table of contents if you are getting no results when using the quick search feature.
Printing You will likely want to print out some or all of the pages from this manual to use in the workshop. Even if you want to print the whole manual you will probably not want to print out these first couple of pages. All of the printing options are located at File -> Print or CTRL + P. The most important options are in the page range box. If you printed this manual now it’s likely that your printer would automatically print every page. If you want to omit some pages or only print certain page numbers you should to click the Pages button rather than All in the page range box. Now enter the page numbers you wish to print, for example 2-40 or 18-22. If you are planning to print only a certain section of pages be sure to use the page numbers that are shown on the toolbar and not the page number shown on the actual page.
If you are planning to print this entire manual it is recommended that you print on both sides of the paper. It looks nicer and you use half as much paper. Some printers have duplex printing where the printer can automatically print on both sides. If your printer doesn’t have duplexing capabilities it will take more work. First you need to print off the odd pages. To do this select odd pages only in the print setup. Before you start to print, we recommend you label the different sides of the first sheet in your paper tray because depending on your printer it may be hard to figure out which way to correctly put the paper. Once you have printed out the odd pages just flip the stack of papers around according to the markings you made earlier and print the even side. Then put it in a binder, folder etc

r. INTRODUCTION The MF 9 Baler has been designed with a lower feed housing metalwork silhouette to allow the operator to have a full view of the back field as well as the front field from the tractor's seat when in field operation. This Baler is solely a PTO driven unit which is fully automated and requires no additional manpower other than the tractor operator. From the time the windrowed material is picked up at the 56" wide pick-up assembly, until the baled material is discharged from the 14" x 18" bale chamber, the p~unger i~ operating at 80 strokes per minute when a PTO speed of 540 rpm is maintained. The MF9 Baler contains a twine tie mechanism which ties the material being baled. The bale lengths can be controlled in lengths from 12" to 50" by a simple adjustment of the metering wheel. Being able to control the bale length permits the operator to store bales in a number of storage places instead of being restricted to anyone area because of bale size restrictions. Weight of the bales are dependent upon the size of the windrow, moisture content, baling speed, material texture and the adjustment of the bale tension bars. Fifty to sixty-lb. bales are average weight. If bale weight is allowed to exceed 80 lbs. in hay and 65 lbs. in straw, excessive twine breakage will occur during handling due to the limit of the twine tensile strength. Incorporated in this highly engineered Baler are sealed needle and sealed ball bearings, oil impregnated bronze bushings and oil impregnated cheveron type nylon bushings. As a result, the MF 9 Baler requires little more than seasonal iubrication. When reference is made in the manual as to direction of travel or location of Baler parts, the following is indicated: the drawpole is located at the front; the tailgate is at the rear of the Baler; when reference is made to left side or the right Side, it is assumed that the operator is standing at the rear of the baler. Other commonly used terms in this manual are: Compression Stroke - when the plunger moves toward the rear of the Baler, compressing the material being baled; Return stroke - the plunger has completed its compression stroke and is returning toward the front of the Baler; Primary Twine - end of twine held in the twine holder discs which encircles the rear portion of the bale; Secondary Twine - end of twine threaded in the needles which is placed in the motters encircling the front portion of the bale.

PERIODIC MAINTENANCE A regular schedule of inspection, lubrication and maintenance at periodic intervals will give you additional years of field service from your MF 9 Baler.
terial to enter the needle bearings, shortening their life.
BALER LUBRICATION Care should always be exercised when handling all types of lubricants. Open containers invite and collect dirt, which may cause very serious damage to the lubricated parts. Secure a good grade of lithium base pressure gun lubricant from a reliable supplier to be used in the pressure-type grease fittings. Always wipe off grease fittings before lubrication to prevent the entrance of dirt.
To obtain access to the PTO drive shaft lubrication holes, first, detach the PTO drive shaft coupler from the tractor. Pull universal drive shaft apart and apply lubrication to shaft, then, reassemble. NOTE: Apply a sufficient amount of
engine oil to maintain easy telescopiC action of the PTa shaft.
The points listed below should be lubricated periodically. The number of hours indicates the hours of operation after which these points ¡ should be serviced. I

OPERATION It is important that your MF 9 Baler's mechanism has been properly and correctly adjusted for field use. Time lost in the field due to mechanical failure is usually attributed to the lack of preventative maintenance and proper adjustment procedures.
Refer to this Manual before making your next mechanical adjustment
PRE-OPERATING INFORMATION PTO DRIVE
The PTO drive Baler is used to its best advantage when used in combination with a tractor having a two-stage clutch system or Independent PTO.
knotters operate in a conventional manner. The primary twines are held in the cord discs as the bale is being formed. When the bale has reached its pre-determined length, the knotter is tripped by the metering wheel assembly, thus tying the bales before being discharged from the rear chamber.
The two "U"-jolnt PTO drive transmits power from the tractor engine through the tractor PTO shaft to the baler.

PTO ORA WBAR HITCH
When using a PTO driven Baler, the tractor must be equipped with a PTO drawbar hitch that conforms to A. S. A. E. standards. This requirement calls for 14" from end of tractor PTO shaft to the center of the drawbar hitch pin hole. Refer to Fig. 6. Either the extension "V" drawbar, Fig. 7, swinging drawbar, Fig. 8, or the universal drawbar, Fig. 9, can be used when attaching the MF 9 PTO driven Baler to the tractor. When using the extension "V" drawbar kit, a 12" PTO shaft extension with support housing must be used; a 6" PTO shaft extension must be 6

PREPARING THE BALER (Twine Tie)
7. Do not attempt to operate Baler until it has been properly adjusted, otherwise, serious damage to the Baler mechanism may occur.
Before entering the field to bale, the baler should be properly prepared. This includes the basic pre-operative settings, placing twine in the twine container and correctly threading the needles with twine. Refer to "Adjustment" section in this manual for further information on the Baler.
CAUTION: Make sure that the tractor PTO shaft safety shield is in place before operating.

The packer should be positioned in the extreme right hole, No.2, on the pac~{er relief spring rod, refer to Fig. 14, before startin~ operations. To compensate for varying hay and straw conditions, the packer may be placed in either of the two other positions.
If the bales tend to bow as they leave chamber, more material should be added to the concave side of the bale. This is done by incr easing or decreasing the throw of the left packer assembly.
To increase the throw of the left packer, remove the connecting pin from 'the upper end of the packer and move the packer assembly to the right hole in relief spring rod. Moving the packer to the left on the rod will decrease the throw. For additional information, refer to "PACKER FORK POSITIONING" paragraph under "OPERATING ADJUSTMENTS" in this Manual.

PREPARING TWINE BALLS
The twine container at the rear of the pick-up assembly has a capacity of four balls of twine placed beside each other; refer to Fig. 15. Top quality twine should always be used to obtain the best results from the knotter assembly and the necessary holding quality when wrapped around the bales. When placing twine container, pers around the ture unraveling being used.
the four balls of twine in the side by side, leave the wraptwine balls to prevent premaof the twine as the coils are
Always place end of ball in twine container as recommended by the manufacturer. Twine from the balls of "A" and "B" of Fig. 15 is used to thread the needles, with ball "A-I" attached to ball "A"; ball "B-1" attached to ball "E". Tie the inside twine of ball "A-I" and "E-l" to the outside twine of balls "A" and "B". Attach balls with a s,quare or a modified square knot
PROCEDURE: Unravel both ends of the twine back about 1-1/ 2", then insert the frayed ends into each other. Roll these mated ends between the fingertips, thus forming an endless piece of twine. Then, tighten the knot securely. Push both knots into the center of the balls to prevent fouling of the twine as the new ball is started. Remember, this knot must be small enough to pass freely through the guides and the eyes of the needles.
THREADING NEEDLES
1. Thread the twine from the center of balls "A" and "E", Fig. 15 , through the twine guides, No.6. 2. Pull the twine toward the left and through the container guides, No.5, Fig. 15. 3.

4. Operate baler at normal operating speeds ¡and check to see if all the mechanism is operating correctly. Then, stop unit.
STOPPING TRACTOR
When baling in the field and a stop must be made, depress the tractor clutch through the first stage only. This action stops the forward movement of the tractor and permits the baler operation to continue, thus clearing out the pick-up and bale chambers. If this procedure is not followed and the packer assembly stalls in the chamber, come to a complete stop, tum off engine and clean out clogged baler by hand.
A
CAUTION: Always turn off tractor engine before attempting to clean out or a dj u s t Baler ¡ assembly. Do not attempt to operate Baler until it has been sufficiently cleaned out.
STOPPING TRACTOR AND BALER
To stop the baler operation, depress the clutch through the second stage (PTO clutch).
NOTE: If the baler operation is to be s topped for long periods of time, return the PTa shift lever to its neutral position.
FIELD OPERATING INFORMATION TRACTOR SPEED
Both a steady rate of material feed into the pick-up chamber as well as continuous forward travel of the tractor can be had when baling material from Windrows, if the proper forward gearing ratio for the tractor is selected at the start of the windrow. It is recommended that the operator start the tractor at the beginning windrow in low gear, rut, at the same time, maintain sufficient engine speed for constant 540 rpm speed of the PTO input shaft to the baler. If it is found that the baler will handle more hay, shift up a gear rather than increasing the tractor's engine rpm. BALER OPERATING SPEED
The recommended baler plunger operating speed is at 80 strokes per minute for the PTO operated baler.
IMPOR TANT: The baler should not be operated above 540 PTa rpm, or 80 strokes per minute. PTO DRIVEN BALER
With a PTO driven baler, the operator engages the tractor PTO shift lever into "Engine PTO", Fig. 19, releases the clutch through the second stage and speeds up the engine to apprOximately 1700 rpm to acquire 80 plunger strokes per minute plunger speed.

PREPARING FIELD FOR BALING
When preparing the field for pick-up with th baler, it is suggested that the material b mowed, raked and picked up in a clockwise di rection. Under normal conditions, one mowe swath will give the windrow the desirable uni formity and size for bales of even denSity. ] is important to rake and turn all of the ha) Unraked hay under the windrow does not dr proper ly and it is hard for the baler to pick ul Generally, if two swaths are combined int one windrow, it may cause bunching of mater ial, which will take more time for drying 01 and result in uneven baling and is likely to hav internal mold. It is strongly recommended that, before th baling operation is started, the windrowE material should be dry enough to ensure sal storage of bales.
BALING PROCEDURES
Baling can be started in either of two dire, tions:
A
CAUTION: Always turn off tractor engine before attempting to clean out or a dj u s t Baler ' assembly, Do not attempt to operate Baler until it has been sufficiently cleaned out.
STOPPING TRACTOR AND BALER
To stop the baler operation, depress the clutch through the second stage (PTO clutch).
NOTE: If the baler operation is to be s topped for long periods of time, return the PTa Shift lever to its neutral position.
FIELD OPERATING INFORMATION TRACTOR SPEED
Both a steady rate of material feed into the pick-up chamber as well as continuous forward travel of the tractor can be had when baling material from Windrows, if the proper forward gearing ratio for the tractor is selected at the start of the windrow. It is recommended that the operator start the tractor at the beginning windrow in low gear, rut, at the same time, maintain sufficient engine speed for constant 540 rpm speed of the PTO input shaft to the baler. If it is found that the baler will handle more hay, shift up a gear rather than increasing the tractor's engine rpm.
BALER OPERATING SPEED
The recommended baler plunger operating speed is at 80 strokes per minute for the PTO operated baler.
IMPOR TANT: The baler should not be operated above 540 PTa rpm, or 80 strokes per minute. PTO DRIVEN BALER
With a PTO driven baler, the operator engages the tractor PTO shift lever into "Engine PTO", Fig. 19, releases the clutch through the second stage and speeds up the engine to approximately 1700 rpm to acquire 80 plunger strokes per minute plunger speed.

PREPARING FIELD FOR BALING
When preparing the field for pick-up with the baler, it is suggested that the material be mowed, raked and picked up in a clockwise direction. Under normal conditions, one mower swath will give the windrow the desirable uniformity and size for bales of even denSity. It is important to rake and turn all of the hay. Unraked hay under the windrow does not dry properly and it is hard for the baler to pick up. Generally, if two swaths are combined into one windrow, it may cause bunching of material, which will take more time for drying out and result in uneven baling and is likely to have internal mold. It is strongly recommended that, before the baling operation is started, the windrowed material should be dry enough to ensure safe storage of bales.
BALING PROCEDURES
Baling can be started in either of two directions: 11
1. Clockwise, skipping the first windrow until the bales are removed, allowing a counrclockwise pass to bale outside windrow. - / 2. The operator can bale the outside windrow first in a counterclockwise direction, picking up the bales or moving them to the outside of the field before baling the remainder of the field in a clockwise direction. 3. When a wagon is being used, the bales will be loaded directly on the wagon and the above steps will not apply. .
this purpose. Always order shear bolts by above part number.
IMPORTANT: If a shear bolt is sheared, a careful check should be made to determine the cause. After finding the cause, r eplace the shear bolt. Turn the flywheel by hand to d etermine if all parts are working freely .
OPERATING ADJUSTMENTS Some operating adjustments must be made during operation of the baler in order . to meet changing field conditions, crop density and wear of baler parts.
PTO SLIP CLUTCH AND OVER-RUNNING CLUTCH
Incorporated within the rear of the PTO shaft assembly, adjacent to the flywheel, is an overrunning clutch and a slip clutch. The over-running clutch allows the baler mechanism to coast to a standstill whenever the tractor PTO comes to an abrupt stop. This prevents any backlash through the power train

SHEAR BOLT
The special shear bolt (Part No. 153221 M2), Fig. 20, in the flywheel is a safety measure designed to prevent machine damage in event of excessive load, or where foreign material gets in the path of the shear knives. This bolt will shear if the baler is in danger of being damaged, thus, stopping all power being transmitted into the baler via the flywheel. Should the bolt shear, do not, under any circumstances' replace the bolt with any other than the machine-head bolt made especially for

maintenance of chains cannot be over -emphasized. The baler has a total of 5 chains which must be kept correctly adjusted for satisfactory operation. Timing of the baler should alwav begin with chain adjustment
IMPORTANT: Correct timing of the machine is dependent on the chains and this can be accomplished only after all chains have been properly adjusted. When making chain adjustments, a good rule to follow is to remove all slack while still maintaining between 1/ 4" and 1/ 2" deflection under hand pressure on the tight side of chain. The main drive single pitch roller chains, Figs. 23, 24 and 25 , are adjusted with the idler type chain tighteners. The double pitch drive

between the flywheel and the tractor engine, which may cause undue strain to any portion of these components. The PTO slip clutch limits the torque input into the baler and prevents over loading the baler, regardless of the size of the tractor used during operation. Fig. 23 - Adjusting the First Main Drive Chain
To pre-load springs for field operation: 1. Remove the three machine screws securing the clutch cover in position. Slide the cover away from the flywheel, Fig. 21. 2. Turn the bolt head, No.2, Fig. 22, on each of the six clutch spring bolts until the nut on the backside bottoms. This will correctly pre-load the springs for operation. 3. Replace the cover and secure in position with the three machine screws.

PACKER RELIEF SPRING ASSEMBLY LENGTH
The effective length of the packer relief spring, Fig. 28, should be 25-1 / 4" from one pivot point to the nearest hole in the spring rod assembly. This setting will properly pre-load the packer relief spring, which requires an approximate force of 100 lbs. for each one-inch deflection at the points of the packer fingers. This distance is measured between the center line of the adjusting hole, Fig. 28, and the center line of the packer relief spring pivot point.

CAUTION: When adjusting the spring length, take care not to allow the preloaded spring to become free. as this could cause personal injury .
NOTE: WIlen the packer r elief spring length is changed, the pac/~er finger plunger timing mus t be che cked and retimed, if necessary . PACKER CRANK TIMING
In order for the packer assembly to operate properly (moving the material from the right packer to left into the bale chamber). the packer crank movements must be synchronized. To check, turri the baler mechanism over slowly by hand (turn flywheel counterclockwise, as viewed from the front) until the left packer crank is at the bottom dead center. At this time, the right packer crank should also be at bottom dead center and the two packer cranks parallel to each other to the nearest possible chain tightener sprocket tooth. With the left packer crank in the bottom dead center position, the right crank may be slightly off cente when the chain is properly tightened (but On, when movement of the sprocket one tooth h either direction would cause the crank alignment to be further off). To adjust packer cranks, proceed, as follows: 1. Position the left packer crank at bottom dead center. 2. Loosen the chain tightener, remove the roller chain and posi tion the right packer crank in bottom dead center. 3. Reassemble the chain with the right packer crank parallel to the left packer crank (to the nearest sprocket tooth) and tighten the roller chain until all slack is removed.

more material should be added to the concave side of the bale. Refer to Fig. 30. This is done by increasing or decreasing the throw of the left packer assembly . To increase the throw of the left packer assembly, remove the packer positioning pin, No. I, Fig. 29, and move the packer assembly to the right on the relief spring rod to hole, No. 3, Fig. 29. Moving the packer to the left hole in the spring, No . 4, will decrease the throw . PACKER FINGER-PLUNGER TIMING
To check this timing, proceed, as follows : 1. Turn off tractor's engine before timing. 2. Position the left packer assembly in its extreme inward throw position; see Fig. 29. 3. Check all roller chains to make sure they have been tightened. 4. Rotate the packer crank one complete cycle to eliminate backlash (turn flywheel in a counterclockwise direction as viewed from the front). . 5. Position plunger knife edge, No . I, Fig. 31, on its return stroke, directly opposite of left packer finger's bottom end, No.2. 6. Use a yardstick, as shown in Fig. 31, and measure the distance between the left end of the packer finger and knife edge.

1. Make certain that the left packer fork assembly, Fig. 29, is in the innermost throw position. Refer to Items 4, 5 and 6 under "Packer Finger -- Plunger Timing", page 16, and proceed accordingly.
6. Rotate the flywheel until the Baler has completed one cycle and recheck the timing dimension to make certain it is correctly adjusted for the 5" to 5-1 / 2" specification. 7. Reposition the packer in the outer position. TRIPPING THE KNOTTER CLUTCH
This is . necessary for various timing adjustments. Normally, if the flywheel is rotated with no hay passing through the machine, the metering wheel will not rotate, and the knotter mechanism will not operate. In order to operate the knotter mechanism while turning the flywheel by hand, the knotter clutch must be tripped. This is achieved by lifting the metering arm assembly, No.1, into the position illustrated in Fig. 33. The metering arm may be lifted by hand (pull back on arm and lift up ) or raised by rotating the metering wheel. Make sure that the arm is raised as far as possib. This, in turn, will move the metering ph Fig. 32 - Pick-Up in Transport Position" J. Timing Gear
2. Remove the two capscrews from timing assembly, No.1, Fig. 32. 3. With plunger stationary, manually move packer in against plunger knife edge and then back away from plunger until the 5" to 5-1/ 2" dimension is obtained. Refer to Fig. 31. 4. Replace cap screws. 5. If two holes of chain sprockets do not align with hub holes, rotate sprocket in chain until holes in sprocket align with holes in hub.

To adjust: Advance the nut, No.4, on each adjustment bolt until the nut and washer just begin to exert pressure on the spring. Then, advance the nut an additional 1-1/ 2 to 2 turns. Excessive brake drag will cause a violent clutch disengagement as well as contributing jerking motion to the knotter clutch during operation (due to the fact that the needle frame

--
During a tying cycle, the stop begins to enter the bale chamber until it contacts the underside of the plunger. The stop enters to the fully "in" position only after the plunger passes over the stop on its return from the compression stroke. The stop remains in the path of the plunger until the needle swing frame returns to "home" position, retracting the stop from the bale chamber. This action prevents the plunger from fbrcing a new charge of material against the needles if they have not returned to "home" position, as the plunger would hit the stop and the flywheel shear bolt would be severed.

The stop and its components, at this time, should be free of binds or restrictions to allow unrestricted entry of the stop into the bale chamber. 3. Continue the movement of the plunger until the stop dog, No.2, has started downward. With the stop in this position, the face of the plunger (not the extension) should be 2-1/4" from the face of the stop. If this distance is not 2-1/4", loosen the locknut on the clevis end of the plunger stop rod, No.4, remove the clevis pin, adjust the effective length of the rod and reassemble.

KNOTTER ASSEMBLY ADJUSTMENTS Particular attention should be paid to the operation and adjustment of the knotters, the most precise, and certainly one of the most important working mechanisms of the baler. Before making any adjustments, it is a good practice to note the original settings so that they can be restored, if necessary. Test after each adjustment. Do not try too many adjustments at one time, as the good results of one may be cancelled out by the poor adjustment of another part. In addition to the adjustments listed in this section, the working parts should be checked for freedom of movement.
NEEDLE ADJUSTMENT The correct alignment and positioning of the needles in relation to the knotters is essential for satisfactory twine tying operation. Unless the needles are positioned accurately as they pass through the bale chamber, they could be damaged by contacting the plunger or other parts. To check needle pOSitioning and adjustment, proceed. as follows:
ance, equally loosen the nu ts securing each needle to the swing frame just enough to allow the needle to be repositioned on the frame; see Fig. 36. Retighten the nuts evenly, then, recheck clearance. 4. Check that the clearance between each needle and twine holder disc is within 3/32" to 1/8". Refer to Fig. 38. 5. To adjust the above dimension, loosen one nut, No. 1, Fig. 36, on the needle 1/ 4 turn and tighten the remaining bolt 1/ 4 turn; this will "rock" the needle on the swing frame. Tightening the front bolt will decrease the clearance between the needle and the twine holder disc and, by tightening the rear bolt, it will increase the clearance.

NOTE: When the ¡operawr is turning the baler mechanism over by hand, the knot which is formed may not completely s trip off the kno tter hook. This should be rechecked when the baler is running at normal operating speed. Baler must have material in the chamber before tying operation can be completed

NOTE: If, at any time, the needle bolts frYe wosened, the needle must be r eadjus ted.
6. Then, rotate the flywheel until the needles are at their maximum "in" position, until the needle drive arm, No.1, Fig. 39, and the swing frame connecting rod, No.2, are adjacent to, and in line with, each other. 1n this position, the distance, as measured from the bottom of the twine holder disc upward to the top of the needle eyehole, should be 2-3/ 4" to 3"; see Fig. 40. 7. To adjust the above needle pOSition, loosen the swing frame connecting rod clevis locknut, No.3, Fig. 39, ¡remove the clevis pin, No.5, and thread the clevis, No.4, on the rod. One complete rotation of the clevis will reposition the needles approximately 1/ 4" in relation to the distance the needle passes beyond the twine discs. Shortening the rod will bring the needles further past the twine holder disc and, by lengthening the rod, will shorten the distance the needles pass beyond the twine discs. Reinstall the clevis pin and tighten the locknut.
CA,uTION: The swing frame connecting rod should not be shortened so much that the swing frame will contact the underside of the bale chamber during operation. If the connecting rod length is changed, the plunger

TWINE FINGER
The function of each of the twine fingers, No. 2, Fig. 41, is to pick up the secondary twine from the needle as the needle enters the knotter. The finger then places the secondary twine against the primary twine, which is held in the twine holder disc, placing both twines against the knotter hook, and holding them in position until the knotter hook engages them. To check and adjust each twine finger : 1. Trip the knotter, Fig. 33, and, by hand, rotate the flywheel until the leading point of the twine finger is adjacent to the needle. 2. 1n this position, the clearance between the twine finger, No.2, and needle, No.1, Fig. 41, must be 1/16".

Rotate the flywheel until the starter arm roller is moved to its lowermost position by action of the driving cam surface of the knotter gear. 6. Move the twine finger, No. 2, Fig. 41, by hand, to its maximum inward travel position.
This is indicated by the dotted outline. 7. In this position, there should be 1/ 16" clearance between the twine finger and the bale chamber bracket. Move the finger until this setting is attained and then, retighten the locknut, No.4. 8. Recycle the knotter and recheck the settings of each twine finger to ensure that they are correct.
Fig. 43 - Twin. in Knott.r Hook Jaws I. Knouer Hook Ro llers
TWINE HOLDER DISC
The twine holder disc holds the primary end of the twine in each knotter assembly after it as been threaded through the eye of the needle. )he twine is then suspended through the bale chamber, from the twine disc to the needle eye, in the path of the material being baled. The rearward movement of the material
against the primary twine pulls additional twine around the forming bale while the primary twine end is held securely in the twine disc. When enough material has passed through the chamber to rotate the metering wheel, a predetermined amount, the clutch is tripped, driving both needles through the bale chamber and plunger slots, into the knotter. This needle movement places the secondary needle twine adjacent to the primary twine over the knotter hook jaw and into the open notch of the twine disc. The twine holder disc, No.1 , Fig. 42, then rotates one notch, tightly securing the secondary twine between the twine holder fingers and the twine holder disc. This holds both twines in position for the knotier hook, Fig. 43, to pick up during rotation in order to form the knot. After several bales have been produced, a finer adjustment may be desired. This may be made more accurately with the needles threaded and material under compression in the bale chamber. This setting will properly position the two twines in the center of the open knotter hook jaws, as outlined below. 1. Trip the knotter clutch, Fig. 33, rotate the flywheel, by hand, until the knotter hook has completed 3/4 revolution and the jaws are pointed directly toward the twine holder disc.

2. With the knotter hook in this position, the
twines from the twine grip should be midway between the open jaws, as shown in Fig. 43. 3. If the twines are not midway between the knotter hook jaws, loosen the locknut, No.3, Fig. 42, on the cam stud, insert a screwdriver into the gear teeth on the upper side of the knotter disc from behind the disc cleaner stud, and apply sufficient pressure forward on the screwdriver handle to eliminate backlash between the gear teeth, as shown in Fig. 42. Rotate the cam stud, No.4, while maintaining pressure on the screwdriver handle, until the twines are centralized between the jaws of the knotter hook. Retighten the locknut. Complete tying cycle; check to see if you have a 1/ 16" clearance from inside of knotter disc tooth to surface of twine holder arm. If so, it is correctly adjusted. 4. After running several hundred bales, this setting should be rechecked and readjusted, if necessary.
NOTE: The twine holder driving gear is reversible and may be reversed when the driving side of the teeth become worn.
TWINE HOLDER
When baling, sufficient pressure must maintained on the twine holder to keep the ~ mary twine end securely held in the twine dl." " as the bale is being formed, but this pressure must be light enough to allow a sufficient amount of twine to pull through the disc as the knotter hook rotates and forms the knot. Excessive holder pressure may break the twine or damage the knotter hook as the knot is formed. A twine holder spring assembly, No.2, Fig. 44, pivots on, and attaches to, the knotter frame by means of a capscrew . Tightening the capscrew, No.3, increases the pressure exerted by the spring on the arm, and loosening reduces the pressure. 1. If the twine is pulled from the twine disc when forming the bale, increase the pressure on the arm 1/ 6 of a capscrew turn at a time until the twine is held. The operator should bale several bales between each adjustment.
2. If the twine is broken at the twine disc while in the tying cycle, reduce the pressure 0 the arm 1/ 6 of a turn at a time until the twi.; is held without breaking, baling several bale_ between each adjustment. 3. If the twine is broken at the twine disc while the bale is being formed, loosen the tension on the bale tension bars, as the bale density is greater than the twine tensile strength can withstand.
KNOTIER HOOK
The knotter hook, No.1, Fig. 45, rotates one revolution for each knot tied. For the first 3/ 4 revolution, the knotter hook jaws remain closed as they wrap the twines around the jaws. During the last 1/ 4 revolution, the knotter hook moveable upper jaw opens to allow the twines to enter, then closes on and holds them under tension until the stripper removes and completes the knob.

TWINE KNIFE The twine knife, No.1 , Fig. 46, attached to the stripper arm cuts the twines held in the twine holder disc as the stripper moves to strip the formed knot from the knotter hook. Positioning of the knife in relation to each of the following units is a pre-operative check, but a final field check is also necessary , as outlined "'elow. 1. Trip the knotter, Fig. 33, and, by hand, rotate the flywheel, checking each of the following units as the knife passes:

3. Capsc: rews
Clearance between the knife, No. 1, and twine disc assembly, No.2, should be 1/ 16" to 1/ 8".
b. At all times, the knife must clear the knotter hook as it rotates. c. As the knife returns from the cutting and stripping stroke, it must clear the twine revolving in the twine grip. 2. If an adjustment of the knife is needed, loosen the two capscrews, No.3, securing the knife and move the knife in the desired direction for proper adjustment.
NOTE: A lesser distance than 1/ 16" between the knife and twine griP will leave a long tail, which will not pull through the knot. This will probably result with a bow in the knot. STRIPPER ARM The stripper arm removes and completes the tying of the formed knot from the knotter hook by pulling the twine loops, held in the knotter hook jaws, over the cut ends of the twine. An adjustable torsion spring holds the stripper arm and returns it to the "home" position. This spring should be pre-loaded so that an 8 to 10-lb. force is required to actuate the arm
2. Repeat the above procedure until correct pre-load is obtained on each s tripper arm. Periodic checking and adjustment of .. ,spring pre-load during the baling season is advisable. TWINE TENSION
The twine tension adjustment nu t, No.1, is located to the left of the twine storage container; see Fig. 48. This determines the tension or pre-load on the twine as it is pulled into the knotters. 1f there is no tension, the rapid action of tying would cause the twine to over-run and snarling would occur, either at the twine storage container, or at the knotters.

2. Back off the locknut and adjust the spring pre-load with the adjusting nut, No.3, Fig. 51, and turn the locknut, No.2, until approximately 3-1/ 2" of thread is exposed above the adjusting nut, No.3, Fig. 51.
Floatation for the pick-up is governed by the adjustable floatation spring, No . 2, Fig. 51, mounted on the left side of the pick-up assembly. This floatation allows the pick-up to raise easily when encountering rough terrain, minimizing damage to the pick- up . Ease of floatation also facilitates adjusting the operating positions and aids in positioning the pick-up assembly in transport position.
PICK-UP FLOATATION ADJUSTMENT
To adjust the pick-up floatation, proceed, as follows : 1. Lower the pick-up assembly to baling op,¡ating position to gain access to the locknut, No.2, Fig. 51, on the underside of the support rib. 26

2. Lower the pick-up from transport position and check ground clearance. Fig. 52 shows pick-up in operating position.
This adjustment is accomplished by using one of the two positioning holes located in each side of the pick-up metalwork; see Fig. 53. When operating the baler in normal conditions, the lower hole must be used. Only with these two holes will the limit stop (located on the extreme left of the assembly) prevent the windguard from raising above the level of the pickup pressure plate, causing the flow of material to become restricted.
B. Transport Position
The upper hole should be used only with light windrows. Downward pressure on the windguard fingers is pre-set at the factory.
1. Select hole in the support arm which will allow the pick-up to gather the material without allowing the teeth to engage the ground. Secure in place. Refer to Fig. 52.
1. Lift the pick-up assembly upward until the hole in the lower end of the support arm is above the retaining bracket. Secure in place. Refer to Fig. 50.

The wheel has a variable adjustment feature which allows a bale length setttng of from 12" to 50" (approx. ). In order to adjust the bale length, the adjust-
bale density, and loosentng will decrease bale density. Several bales should be baled after each adjustment to determine if the bale weight and density is correct.
Ie stop, No.1, Fig. 54, should be moved up "r down on the arm. Movtng the stop upward tncreases the length of the bale, movtngthe stop downward decreases the length of the bale . DETACHING BALER METERING WHEEL ADJUSTMENT
Slotted holes tn the bale chamber permit backward and forward adjustment of the metertng wheel tn relation to the metertng arm . This is essential for correct operation. A clearance of 1/ 4" between the metertng wheel and metering arm, see Fig. 55, must be obtatned when the reset cam is tn the downward position.
When detacbtng Baler from tractor, select dry level ground. Uncouple PTO drive shaft from the tractor. Place jack tn the vertical position and raise drawpole until Baler weight is removed from the tractor drawbar. RemOVE hitch ptn securtng drawpole to tractor drawbar. Drive tractor away from Baler.

BALE TENSION BARS
The adjustment of the bale tension bars, Fig. 56, determines the density and the weight of the bale, when baling tn uniform material. The more uniform the crop, moisture, wtndow and baltng speed, the more uniform the bale weight will be tn anyone position of the bale tension bars. _ The bale tension bars are adjusted by turntngthe handles on the rear of the bale chamber. Tightentng the bale tension bars will tncrease

NOTE: If Baler is equipped with a hydraulic bale density cantrol, remove hydraulic hoses from tractor. NOTE: If all of the bales have not been discharged from the bale chamber, it may be necessary to block up the rear of the bale chamber to prevent the Baler from tipping backward. However, when storing for the seasan, remove bales from the chamber.
KNOTTER DIFFICULTIES With a machine that has had extensive service, certain parts of the knotter assembly may have become worn to such an extent that normal adjustment procedures will be insufficient to provide a correctly functioning, smooth running mechanism. For this reason, it is important to check the knotter components for excessive wear on any machine that has been in the field for some time. Often, wear will be made apparent by deep grooves caused by twine rub. Note particularly the knotter hook, twine holder, lmotter disc assembly, and any other part; if they show signs of great wear, replace them, if necessary. Check the knotter hook cam to see that it rides freely on the pivot pin. This is an important point and should be checked by placing a screwdriver, or similar object, on the end of the cam and pressing it to the right. There must be a minimum travel of 1/8" to 3/16" at the lmotter hook end of the cam. TROUBLE

PLUNGER RUNNERS
Operating clearance between the knives is governed by lateral adjustment of the plunger. This is obtained by repositioning the upper and lower angle plunger runners, No.8, which are located inside - left of the bale chamber. To adjust: 1. The plunger knife must be adjusted to the upper and lower right fixed plunger wear plates
The plunger runners, No.8, Fig. 57, on the lower left and upper sides of 'the bale chamber are adjustable through the use of pusher capscrews, No.7, and shims, No.9. These runners are adjustable to maintain a correctly fitted plunger within the bale chamber as the runners wear. The wear plates , No.4, indicated in Fig. 57, are replaceable when worn. When a plate , or plates, are to be replaced, all the plates on that side of the plunger must be changed at the same time. In order to hold the plunger shear knife, No.2, parallel to the bale chamber shear knife , No. 1, it may be necessary to shim the wear plates. When installing new wear plates, it is important that the original number of shims be reinstalled under each plate. A correctly fitted plunger is essential to smooth, quiet operation of the baler, but, of more importance, is proper knife clearance,

until the knife and wear plates surfaces are flush with each other. Shims are provided in the shipping kit to be installed "as needed" between the knife and plunger. These shims are . 005" thick.
NOTE: The sUrface of each knife must not protrude beyond the surface it is being adjusted against. If this condition exists, remove shims until the knife is properly positioned. A 5/ 16" Allen wrench, Fig. 58, is required to remove the socket screws from the shear knives. The 1/ 2" x I " socket screws are for the plunger knife and the 1/ 2" x 1-1/ 4" socket screws are for the bale chamber knife. 2. Chamber knife must be adjusted until the knife is flush with the lower right bal e chamber runner. The same shims as used in Step 1 are to be installed "as needed" between the knife and the bale chamber. 3. Position the plunger knife, No.2, Fig. 57, adjacent to the chamber knife , No.1 , Fig. 57, and, as the knives pass each other, check the clearance between the knives with a feeler gauge. The knives must not contact at any point as they pass and not have greater clearance than. 030 ". This clearance is adjusted by repositioning the upper and lower angle runners, in the left side of the bale chamber, which guide the path of the plunger.

side of the bale chamber, to prevent any pivo t ing action of runners when adjusting. 5. With the plunger knives adjacent to ead; other, adjust the rear, upper and lower pusher caps crews on the l eft side of the bale cham ber until the clearance between the knives is ne greater than. 030".
NOTE: Clearance 1Ilust be lIIailltained the full vertical lengl" of til e imices. 6. Return the plunger to the forward end 01 the bale chamber. With a feeler gauge, check the clearance between the upper and lower right plunger wear plates , and right uppe r and lower plunger runners, when the plunger is positioned against the left runners. Clearance should not be greater than. 030". This clearance should be adjusted by using the front upper and lower pusher caps crews on the left side of the bale chamber. 7. The plunger should be returned to the rear end and the clearance rechecked. 8. After the clearance has been adjusted on both ends of the plunger stroke, securely tighten the four bolts (front a nd rear sets). Tighten the locknuts on the fr ont and rea r , upper and lower pusher capscrews holding the angle runners and, then, turn in the upper and lower center pusher capscrews until they contact the runners.

SHEAR KNIFE AND VERTICAL PLUNGER ADJUSTMENT With a feeler gauge, check the gap between the top plunger wear plates, No.4, Fig. 57, and top plunger runners, No.8, for. 010" to • 040" clearance. If an adjustment is needed, slotted shims are available in sizes from. 015" to . 030"; see Fig. 60. They are installed, as follows: 1. Loosen the three nuts on the left top of the bale chamber sufficiently to allow the long slotted shim to be inserted between the runner and top of the bale chamber. Loosen three nuts on the right side of the bale chamber for fitting the short shim.
2. Continue the plunger movement until the throat opening is completely clear and then, remove the chamber knife by removing the countersunk screws with a 5/~6rt Allen wrench.
NOTE: If shims are present, behind either knife, replace the original shims during reassembly and adjustment. 3. Sharpen both knives, maintaining the original 45 0 knife angle and the straight line of the cutting edge. (Care must be taken not to overheat knife. )
4. Thoroughly clean the knives, shims and mounting surfaces of the plunger and bale chamber. Add lubricant to the countersunk screws and reinstall the knives. Refer to "Shear Knife Adjustment" sec t ion in this manual.
TWINE KNIFE SHARPENING Tighten the nuts and recheck clearance the full length of the plunger stroke on each ~de. . 2.
SHEAR KNIFE SHARPENING The two knives for slicing each charge of material, as it is compressed in the bale chamber' must be sharp and properly adjusted in relationship to each other. Sharp knives which are correctly adjusted require a minimum of power to shear each charge. Also, sharpknives will give each bale slice a smooth, clean-cut edge.
The plunger knife is mounted on the leading edge of the right side of the plunger, while the opposing lmife is mounted on the right side of the bale chamber at the rear of the throat opening. Remove, sharpen and reinstall the knives, as outlined below: ( ' . 1. Position the plunger knife midway in the '. throat opening, and remove the plunger knife by removing the countersunk screws with a 5/16" Allen wrench, as shown in Fig. 58. 34
The twine knives, Fig. 46, must be kept sharp at all times. Usually, they can be resharpened without removal by loosening the knotters, pivoting them upward, and restoring the lmife edges to their original sharpness and cutting angle by means of a sharpening stone. In the case of an excessively blunted knife, however, it may be necessary to remove it in order to do a good job. In the latter case, the following procedure should be adopted: 1. Mark the pOSition of the knife on the stripper arm and identify the knife as to left or right. 2. Remove the knife by removing two capscrews, No.3, Fig. 46, and sharpen, maintaining the original cutting angle. (Care must be taken not to overheat the knife. ) 3. Reinstall the knife on its respective side, advancing the new cutting edge to its former marked position to compensate for the material ground away.
BALER STORAGE The following recommended storage proce-
dures apply to machines which will be idle for 6 months or more. 1. Remove bales from baler and thoroughly clean baler of all field material.
5. Remove all roller chains and store them in oil until next season.
