the "Trouble and remedy" chapter.
Malfunction
Cause, remedy
Grain tank
Grain tank unloading does not work or works poorly
• Check and/or adjust V-belt clutch for grain tank
unloading drive.
• Have shear bolt in drive sprocket replaced.
• Bend misaligned auger flights.
• Clean dirty auger troughs, augers and unloading
auger tube.
Grain losses
Losses of grain may have different reasons. Therefore,
always determine first where the losses occur.
Check combine for leakage losses. Check whether grain
is lost where working parts join, especially check auger
troughs, elevators etc. Extra care should be taken to
check the working parts for good fitting when combining
small seeds. Repair all leaks as necessary.
Losses that are caused by overripe crops or poor
weather conditions must not be taken for combine
losses.
Grain losses that are due to combining usually have four
main causes:
• Losses of grain over the cutterbar
• Losses of grain caused by insufficient threshing
• Grain losses over the straw walkers
• Grain losses over the cleaning stage
• Losses of grain over the cutterbar
• Adjust the reel tine position to suit the harvesting
conditions.
• Adjust the reel speed to suit the ground speed.
• Set the clearance between the reel and the intake
auger properly.
• Adjust the hydraulic fore and aft reel adjustment to
suit the present conditions.
• When working in crops with hanging ears, install a
crop lifter on every second finger.
• Adjust dividers to avoid build-up of material.
• Adjust intake auger height to suit crop conditions.
