LEXION C81 Hybrid Operator's Brochure

Introduction and Safety

This guide has been produced as a reference to operator’s training. The aim is to aid operator’s with familiarisation and settings of CLAAS LEXION combine harvester. This guide does not replace the operator’s manual. More in depth information is available within the operator’s manual.

Your CLAAS combine is designed for output and efficiency but this can only be achieved with the correct operation and maintenance of the machine.

Make sure you are familiar with the operator’s manual before using the machine. The operator’s manual is an integral part of the machine. It addresses the user and contains safety relevant information. Only procedures specified in the operator’s manual are safe.

Read and observe the operator’s manual before starting work.

If you need help understanding the content, contact your local CLAAS Dealer.

Daily zeroing

This should be carried out with the machine running, threshing engaged at maximum speed and with no material in the machine.

The following items need to be zeroed on a daily basis:

1. Set “zero returns”

2. Set “zero yield”

Tips: Learn the working position of the cutterbar in the front attachment menu.

This may also have to be changed when combining different crops.

The working position will have to be re-learnt if the cutterbar is changed.

Settings VARIO Cutterbar

The cutterbar is one of the most important parts of the combine harvester. It is designed to cut and gather the crop from the field.

Dividers

The first part of the cutterbar to make contact with the crop are the dividers. There are two types, a standard and a long divider.

Lifters

It is recommended that lifters should be fitted to CLAAS cutterbars. The lifters should be fitted by placing the first one on the fifth finger from the RHS of the cutterbar and then on every fourth one thereafter.

Tips:

To aid crop feed into the cutterbar table, the table length can be adjusted towards and away from the cutterbar auger.

Make sure that the height of the divider is set so it does not run on the ground.

Set the height the same as the stubble.

Check the lifters everyday, if they are loose or bent remove and replace them.

Tips: Remove any knife play by adjusting the keeps and make sure that the fingers are not rounded or bent. A clearer cutting knife will reduce stress on the knife drive.

If an issue occurs with crop wrapping around the table auger in difficult conditions, there are a number of procedures that can be carried out (try one thing at a time).

One way is to adjust the stripper plates behind the auger. There is also a second scraper under the auger that can be accessed over the top of the auger.

Settings VARIO Cutterbar Adjustments

Settings CONVIO and CONVIO Flex Cutterbar

Knife in Full Flex

Check that the knife is in good condition in order for it to work effectively. This involves replacing damaged or broken sections.

Lifters

It is recommended that lifters should be fitted to CLAAS cutterbars except the CONVIO FLEX. Fitting the lifters will help lift the crop onto the table.

The lifters should be fitted by placing the first one on the fifth finger from the RHS of the cutterbar and then on every fourth one thereafter.

Settings Pre-Separation

De-awning

De-awning can be carried out by operating the lever on the right hand side of the machine, which in turn closes or opens a set of plates under the APS concave. This keeps the crop in the threshing system until the main concave.

Concave Flap

The concave flap can be engaged and disengaged from the CEBIS screen or by the handle on the left of the machine. This adjustment can be made if increased threshing is required.

Further Information Stone Trap

The concave bar creates a larger friction area in the threshing system. The bar can be used to aid threshing in hard crop varieties. Find more detailed information on chapter 7.14.

The stone trap is situated between the front elevator and the APS concave. It is important that the stone trap is emptied regularly to allow for foreign objects to be expelled before they enter the drum. Ensure the lever is in the up and locked position before lowering the feeder housing.

Only engage the concave flap, threshing bar and the disawning plates one at a time.

To obtain initial settings, it is recommended that the ‘CLAAS settings’ are loaded through CEBIS. The operator can use these settings as a starting point so adjustments can be made.

The prime objective here is to remove the maximum amount of grain with minimum damage to grain and straw. Over-threshing can crack grains, produce more chaff and use more power.

It is imperative for the performance of the machine that the concaves are kept clean. Generally, wider concave gaps are accepted when using a LEXION.

Tips: Only make one adjustment at a time.

Only do just enough threshingover threshing causes overloading of the sieves and uses power unnecessarily.

It is recommended that the drum speed is adjusted by 50rpm at a time.

Settings Separation

De-awning

The rotor cover plates can be opened or closed during threshing. The cover plates should be open when maximum separation is needed.

If the combine is fitted with 4D SEPARATION, there are now four sets of doors. They can be operated in the same manner as the standard rotor cover plates. Either from the armrest or from the CEBIS screen.

Tips:

In situations where the straw is breaking up, it may be beneficial to close the rotor cover plates to reduce the sieves being overloaded. To find the correct rotor speed, start with the CLAAS settings in CEBIS and then adjust the rotor speed to suit the conditions on the day.

The straw will only travel along the rotor at one speed. This will differ for every crop, machine and condition.

Depending on the machine, there can be 2 sets or 4 sets of rotor cover plates. These are opened or closed in CEBIS or on the armrest.

AUTOSLOPE and 4D are activated in CEBIS.

Cleaning

Tips:

Settings

Clean the preparation trays daily, this will help keeping a clean sample.

When removing the prep trays for cleaning, blow off the top of the gear box area to remove any chaff and dust.

The preparation pan is the first part of the cleaning system that the grain will come into contact with. Its function is to separate the grain and the chaff. The grain is heavier and therefore goes to the bottom, the lighter chaff goes to the top.

It is important that this is kept clean, to allow this to happen effectively. A dirty preparation pan will cause a poor sample and reduce output.

Depending on machine type, it may be fitted with either 5 or 6 preparation trays.

Hybrid LEXION trays are the same size, therefore can be located into any of the available slots.

Settings Cleaning

Both the top and bottom sieves are adjustable from 0 – 20mm in the cab.

The sieves need to be open enough to cope with high volumes of grain. With wide sieve settings, there is a need for high wind speed. It is recommended that the sieves are only adjusted by 1mm at a time.

The returns should be monitored regularly both in terms of volume and composition. If fitted the returns monitor can be adjusted in CEBIS. The volume of grains in the returns (1) and the volume of material (2).

If the shaft is not visible, returns are excessive.

The straw chopper can be engaged and disengaged from work by operating the buttons on the rear of the machine or via CEBIS. The spreader hood cannot be moved if the chopper is still rotating.

Turn switch up or down this will move the spreader into the first position if it needs to be moved further, release the switch and turn it again.

Make sure the hood has stopped moving before releasing the switch. All the settings for the powerspreader can be set from the CEBIS screen. make sure not to spread too wide.

When deciding what to adjust on the combine to reduce the amount of loss, it is important to understand where the loss is coming from and what is acceptable.

At the front of the machine

Is loss occurring before or after the cutterbar knife?

At the rear of the machine

If it is happening before, it is not cutterbar related.

Tips:

Always check the losses behind the combine after making an adjustment and then set up the monitors to show what is happening.

In the CEBIS machine menu, you will find an optimization guide for operator setting assistance - the same guide can be found in the CEMOS Advisor App.

Are the losses acceptable?

Are they coming from the sieves and/or rotors?

Adjust the reel position or check the knife for damage or wear.

Fit lifters to lift any laid crop or place cutterbar into a flex mode.

If losses are excessive, make sure to check head losses in the crop in-front of the Lexion, this will give the operator a more precise idea as to where the losses are originating.

Losses

After adjusting the combine, make sure that the monitors also reflect what you will accept as a loss.

Adjust monitor sensitivity so that the blue area is approaching the limit lines, the white line. This is particularly important when running CRUISE PILOT and CEMOS AUTOMATIC.

Where are the losses coming from?

To work out what is coming from the rotors; engage the chaff spreader and disengage the chopper, then carry out a check behind the combine and lastly, count the grains on the floor.

To check the losses from the sieve; disengage the chaff spreader and engage the chopper, offset the spreader and then count the grains.

Take into account what the grains look like (unthreshed heads etc.).

Now, make the corresponding adjustments.

Tips:

The easiest way to check for losses is in the swath with the chaff spreader and chopper disengaged.

Count the number of grains within a set area - a hand print can be a sufficient guide.

For the FIELD SCANNER

> Select the steering symbol (1) turn on the steering, then select the sensor.

> To activate, press the AUTOPILOT button on the multi function control handle when you are lined up with the edge of the crop.

TIP: Make sure that the width of the cutterbar has been set in the front attachment menu. Adjust the sensitivity and offset so the FIELD SCANNER follows the edge of the crop.

> Press button (2) to change the detection area that the FIELD SCANNER will work within. It will light up as follows...

> Press once, left edge of the crop: indicator light will appear white.

> Press a second time, right edge of the crop: indicator light lights up green then press a third time. Wheel track indicator light flashes white and green.

TIP: If the LASER PILOT is not steering straight ahead, check the centralising and sensitivity first in the steering menu.

When Using GPS PILOT

To turn on,

> Select (1)

> Select GPS

Make sure that the main screen for the GPS is on.

The Quick access menu (1) contains the “Reference track” menu (2). The recording process is started by selecting a track type.

The following reference lines can be created:

> A=B straight line

> A=B contour

> A+ angle

> Manual entry

Track planning

A=B straight line

> Drive to position and set point A (1)

> Drive to the end point and set point B (2)

> The reference line is created under the name A=B and the time stamp (3)

CRUISE PILOT adjusts the ground speed while combining. There are three different driving strategies that can be selected with CRUISE PILOT:

CRUISE CONTROL

(constant ground speed)

Performance

(constant throughput)

Throughput

(throughput with monitoring)

It is important that the “zero throughput” value is learnt daily or after adjustment to the feeder housing chains (see daily zeroing).

1. Turn on Master Switch

3. If in CRUISE CONTROL,

4. Set max speed

5. Set target throughput

7. Set CRUISE PILOT sensitivity

8. Learn zero throughput

To engage CRUISE PILOT, press the AUTOPILOT button on the joystick.

To de-activate CRUISE PILOT, either move the C-MOTION lever or tap the service brake pedals lightly.

To monitor CRUISE PILOT, locate the bottom of the CEBIS screen which displays the CRUISE PILOT limiting factor once in work. The machine will always have a limiting factor. For a more in-depth explanation, use the QR code on the rear of the booklet to view the operation video.

Use the QR code on the back of the booklet to get the video for setting up CEBIS in the field.

Tips:

Make sure that the combine has crop going through it before pressing the AUTOPILOT button on the joystick.

If just using CRUISE CONTROL, (fixed ground speed) drive the combine into the crop at your desired speed then press and hold the AUTOPILOT button for 3 seconds, there will be a beep from the CEBIS screen. This speed is now saved.

If using performance mode (constant throughput), set the target throughput and then increase until you reach your desired throughput. Alternatively, drive into the crop until the desired throughput is reached, then press and hold the AUTOPILOT button for 3 seconds

- you will then hear a beep from CEBIS. The throughput is now saved.

If using the throughput mode, make sure that the loss & return monitors are adjusted accordingly. Be sure to check your losses!

The maximum layer height is reached

Maximum diesel engine output utilisation is reached

The diesel engine protection has responded

The maximum pre-set throughput is reached

The maximum pre-set ground speed is reached

The separation loss limit is reached

The cleaning system loss limit is reached

The returns grain limit is reached

The returns volume limit is reached

Adaption: The machine adapts to new harvesting conditions

The unloading mode is activated

The turning area is identified

The symbol displayed in “4” is the limiting factor of CRUISE PILOT.

Now adjust the relevant limiting value.

To set throughput with monitoring, drive the combine into the standing crop so that the loss monitors are full to the white line. Then check that this is what you accept as a loss.

During unloading, the CRUISE PILOT automatically changes to unload mode which gives a constant speed, this will can be up to 15% less than the current forward speed. The unload mode can be turned off in CEBIS. Use the QR code on the back of the booklet to get the video for setting up CEBIS in the field.

LEXION now has the option to make CEMOS

When changing the crop type, make sure that CEMOS is not available for all crop types.

Check that the preparation floor are clean.

The machine is lacking performance.

What are the settings in CEBIS, what are the crop and field conditions. When chopping check that the knives are sharp, the belt is set correctly.

Wet Harvest Recommendations

In wet and laid crops

It is even more important to get a good cut and feed into the combine. Check the knife and fingers regularly, paying particular attention to the knife to finger gap.

To pick up laid crops

For the VARIO cutterbar, the skids under the bar must be raised into their highest position. This will also reduce the amount of soil sticking to the underside of the cutterbar. For the CONVIO FLEX cutterbar, change the mode to a flex mode.

Soil and foreign objects

These are more likely to enter the combine in a wet harvest, it is vital that the stone trap be emptied at least daily. The more irregular the conditions, the more frequently this should be done.

If the preparation pan is dirty

This is your first indication that further cleaning inside the combine may well be required. When cleaning the rest of the combine, follow the path of grain through the machine, and open covers as you come to them.

Under the concave is the preparation pan

This will become dirty as wet grain and soil passes over it. The dirtier it becomes, the less effective it will be, and hence, the dirtier the sample will become. With wet grain, it is important to try and keep to a cleaner sample than normal.

Emptying the stone trap

Check that the APS concaves are clean. To do this, simply open the concave to 50mm before switching off and emptying the stone trap.

Wet Harvest Recommendations

When unloading wet grain

Reduce the flow into the unloading auger by shutting down the baffle plates on both cross augers in the grain tank. This will reduce the load on the unloading system.

In wet conditions

It is possible for material to stick to the return floor under the rotors. This then impedes the flow of grain back to the preparation pan and affects the sample. Check the pan regularly and clean as required.

If wet and dirty grain is being unloaded

It is also likely that dirt will build up in the turret auger. This can and should be checked regularly through the inspection doors, and cleaned if required.

Chopper blade wear

This can be accelerated when chopping wet straw due to the increased levels of soil in it. Check the condition of the blades regularly. Do not forget to check the stationary blades.

Chopping wet straw

This adds an extra load to the chopper drive. Regularly check the tension of the drive belts and the blade condition. Do not forget the 2 ‘stops’ at either end of the main tensioner.

If the shear bolt on the unloading drive fails, 130l/s unloading system

This is often the first sign that either the slides in the tank are too high, or there is too much dirt in the system, check auger timing.

Seasonal calibration

At the beginning of the season before the combine is used, it is advised that certain procedures are learnt. This is done by navigating to the ‘service menu’ then ‘learning procedures of machine’. Follow the prompts on the CEBIS screen.
