  • Page 4: Introduction

    This quick reference guide has been produced to aid operators with familiarisation and settings of CLAAS LEXION combine harvesters. CLAAS combines are designed for output and efficiency but this can only be achieved with correct operation and maintenance of the machine.

  • Page 5: Safety

    Safety Safety is of the utmost importance whilst you are operating and maintaining your combine harvester. Make sure that all of the risks are assessed to reduce the likelihood of an accident. Make sure you are familiar with the controls and operation of the machine and have read the operators manual.

  • Page 21 CEBIS Calibration To allow the machine to display accurate information certain parameters need to be ‘learnt’ either on a daily or seasonal basis. Daily zeroing This should be carried out with the machine running with threshing engaged at maximum no load speed. The following items should be zeroed on a daily basis.
  • Page 22 If a problem occurs involving the AUTO CONTOUR response, always try learning the cutting height limits before contacting the service department of your preferred CLAAS dealer. Working Position Don’t forget to learn the working position of the cutterbar within CEBIS to avoid inaccurate yield measurements.

  • Page 23: Cruise Pilot

    CRUISE PILOT The CRUISE PILOT automatically adjusts the ground speed while threshing in order to maximise the output of the Combine (Not available for LEXION 740). There are three different driving modes that can be selected with CRUISE PILOT. Cruise Control (constant ground speed) Performance (constant throughput) Throughput (throughput with loss control) It is important that the “zero throughput”...
  • Page 24 Activating the CRUISE PILOT Engage threshing and the cutterbar, ensure the engine is running at the maximum speed. Drive into the standing crop at no less than 2km/h. Ensure that the combine has crop going through it and then press button (2) on the joystick for 2 seconds.
  • Page 25 Setting the Throughput in Performance Mode The maximum speed limit must be set to prevent the Combine accelerating excessively in thin crops. Select the CRUISE PILOT sub- menu in the main menu (1) Set the CRUISE PILOT max ground speed using rotary switch (3) shown on the previous page After the maximum ground speed has been set, the target throughput can now...
  • Page 26 Setting the Throughput with loss control Set the CRUISE PILOT the same as described in the previous throughput section, drive the Combine into the standing crop to the maximum amount of loss that is acceptable. Adjust the sieve loss sensitivity so that the loss triangles are shown half full.
  • Page 27 With the aid of the CEMOS software, losses are reduced, throughput increased and grain quality improved. Cebis mobile can also control other CLAAS systems such as GPS steering and Iso-bus on tractors...

  • Page 31: Threshing

    Threshing To obtain initial settings it is recommended that the ‘CLAAS settings’ are loaded through CEBIS, these are to only be used as a starting point, then adjustments should be made from there. Often changing one thing can effect another.
  • Page 32 Pre-Separation De-awning De-awning can be carried by out operating the lever by the right hand front wheel of the machine, which in turn installs a set of plates under the APS concave. This gives the crop an extra ‘rub’ which in turn threshes it harder. They must only be installed when threshing is stopped.
  • Page 33 Separation (Rotors) Approximately 70% of the grain needs to be separated from the straw by the time the crop leaves the drum. This means that the remaining 30% has to be separated by the rotors. Rotors It is important that the rotor speed is set correctly. This is when the remaining grain is separated from the straw without damaging it.
  • Page 34 Separation (Walkers) Approximately 90% of the grain needs to be separated from the straw by the time the crop leaves the drum. This means that the remaining 10% of the grain has to be separated by the straw walkers. Straw curtain As the crop leaves the impeller a straw retarding curtain is fitted to control the throw of the material onto the walkers.

  • Page 35: Separation

    Separation Preparation pan The preparation pan is the first part of the cleaning system that the grain will come into contact with. It’s 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.

  • Page 36: Cleaning

    Cleaning Sieves Both the top and bottom sieves are adjustable from 0 – 20mm in the cab through CEBIS. The sieves need to be open enough to cope with high volumes of grain, over 16mm is not uncommon. With wide sieve settings there is a need for high wind speed.

  • Page 37: Straw And Chaff Management

    Straw & Chaff management Chaff spreader The chaff spreader is situated at the back of the top sieve, the speed of the discs should be adjusted so that the material is spread evenly and over the full working width of the combine (if fitted). Straw chopper The straw chopper can be engaged and disengaged from work by operating the...

  • Page 42: Maintenance

    Maintenance A full maintenance schedule is provided in the operators book and this should be followed to ensure reliable operation of the combine. When checking belt tensions there are three main types of tensioner that are fitted to LEXION Combines: 1.
  • Page 43 Maintenance Sieve box drive – The sieve box drive belt differs slightly from the others on the machine in that to check the tension of the belt the nut, B, needs slackening, then the spring length F can be set to the guide D.

  • Page 45: Frequent Questions

    When chopping check that the fine chop step is not engaged and the stationary knives are backed off. If these simple solutions do not cure the problems please contact the service department of your preferred CLAAS dealer.

  • Page 46: Wet Harvest Recomendations

    harvest recommendations With 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 (keep adjustment). To allow the cutterbar closer to the ground when picking up laid crops, the skids under the bar must be raised into their highest position.
  • Page 47 harvest recommendations Some dirt can usually be removed from both the cross auger covers, and the bottom covers on both the clean grain and returns elevators. When unloading wet grain, reduce the flow into the unloading auger by shutting down the slides on both the cross augers in the grain tank. This will reduce the load on the unloading system, bringing it down to a ‘normal’...
