8. Some dirt can usually be removed from both the cross auger covers, and
the bottom covers on both the clean grain and returns elevators.
9. 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.
10. 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.
11. If the shear bolt on the unloading drive fails 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, or both.
12. Chopping wet straw adds an extra load to the chopper drive. Regularly
check the tension of the drive belts. Do not forget the 2 ‘stops’ at either
end of the main tensioner.
13. Chopper blade wear 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.
14. 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.
Try to keep the combine as clean as possible. Wet/dry chaff etc. forms into lumps
and can fall onto belts causing them to slip. In a ‘stop / start’ harvest, it is easy to
miss daily checks as you may only combine for a few hours at a time. In order to keep
the combine clean you have to go over it and will often spot a ‘job’.
