  • Page 26: Settings

    Settings: 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 machine running with threshing engaged at maximum no load speed. The following items should be zeroed on a daily basis: 1.
  • Page 27 Settings: CEBIS Calibration 1. Learn the AUTOCONTOUR end stops at the start of the season. TIP. Learn the working position of the cutterbar within CEBIS. This may also need to be changed when combining different crops. 2. At the start of each crop make sure you have selected the correct crop type, or your personal crop settings.
  • Page 28 Set the height the same as the stubble. 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.
  • Page 29 Settings: Cutterbar Check that the knife is in good condition in order for it to work effectively. This involves replacing damaged or broken sections. TIP. Remove any knife play by adjusting the keeps, and make sure that the fingers are not rounded or bent. A cleaner cutting knife will reduce stress on the knife drive.
  • Page 30 Settings: Cutterbar Adjustments TIP. Check the height of the auger within the trough of the cutterbar. There should be a minimum gap of 20mm between the trough and the auger flights. TIP. Remove the intermediate retractable fingers along the length of the auger leaving just the middle ones.
  • Page 31 Settings: Side Knife/Divider Both the side knife and the divider use the new fork locating and locking device. For the side knife simply slide into the lock and turn the handle to lock in place. Make sure the lever has locked into the locking device.
  • Page 32 Settings: Pre-Separation De-awning De-awning can be carried out by operating the lever by the right hand front wheel of the machine, which in turn closes or opens a set of plates under the APS concave. This gives the crop an extra ‘rub’...
  • Page 33 Settings: 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. TIP. Only make one adjustment at a time.
  • Page 34 Settings: 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. If the rotor speed is too fast, broken straw and chaff is produced which could lead to overloading of the sieves.
  • Page 35 Settings: Cleaning The preparation pan (1) 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.
  • Page 36 Settings: Cleaning Both the top (1) and bottom (2) 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. TIP.
  • Page 37 Settings: Straw and Chaff Management The chaff spreader can be adjusted to spread chaff wider. See operator’s manual for adjustments. The straw chopper can be engaged and disengaged from work by operating the buttons on the rear of the machine or via CEBIS.
  • Page 38 Settings: Straw and Chaff Management The width that the POWERSPREADER spreads can be adjusted from the cab in CEBIS. TIP. Make sure that the spreader is not spreading too wide and that it is not in the standing crop. TIP. Make one adjustment at a time.
  • Page 39 Settings: Grain Tank Pieces of straw 1. Increase fan speed 2. Open concave 3. Reduce drum speed 4. Close rotor cover plates 5. Close both sieves 1. Close the lower sieve Unthreshed heads 2. Increase the drum speed 3. Close the concave Broken grains 1.
  • Page 40: Losses

    Losses 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 the loss happening before or after the cutterbar? •...
  • Page 41 Losses Where are the losses coming from? To work out what is coming from the rotors engage the chaff spreader and carry out a check behind the combine, count the grains on the floor. To check the losses from the sieves disengage the chaff spreader and engage the chopper and spread this as wide as possible and then count the...

  • Page 44: Easy Cruise Pilot

    EASY: CRUISE PILOT 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 control) TIP. It is important that the “zero throughput” value is learnt after long periods at standstill/idle or after adjustment to the feeder housing.
  • Page 45 EASY: CRUISE PILOT To engage CRUISE PILOT press the AUTOPILOT button on the joystick. The symbols in the HOTKEY direct menu will have the colours inverted on activation. TIP. Make sure that the combine has crop going through it before pressing the AUTOPILOT button on the joystick.
  • Page 46 EASY: CRUISE PILOT Symbols The symbol displayed in the HOTKEY section (1) is the limiting factor for CRUISE PILOT. Now adjust the relevant limiting value. Maximum throughput is reached Maximum diesel engine load reached Ground speed limit, the maximum pre-set ground speed has been reached The separation loss limit has been reached The sieve loss limit has been reached...
  • Page 47 EASY: CRUISE PILOT To set throughput, drive the combine into the standing crop so that the loss monitors are full. Now check the losses. Are these losses acceptable? If not then increase or decrease the sensitivity to show what is acceptable. Adjust the rotor loss sensitivity so that the loss triangles are shown 3/4 up...

  • Page 56: Frequent Questions

    Frequent Questions Threshing won’t engage and none of the hydraulics are working. Check that the road travel switch is not engaged. Threshing has engaged but the engine will not go to full rpm when the engine speed dial is turned. Check that the combine is not in 3rd gear.
  • Page 57: Wet Harvest Recommendations

    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 The skids under the bar must be raised into their highest position.
  • Page 58 Wet Harvest Recommendations 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’ level. If wet and dirty grain is being unloaded It is also likely that dirt will build up in the turret auger.
  • Page 59: Recommendations

    Recommendations Seasonal calibration At the beginning of the season before the combine is used, it is advised that the following items are learnt: A. Learn AUTOCONTOUR limits (1), VARIO (2) and reel (3) ‘end stops’ in the cutterbar section of CEBIS. B.
