Grain quality
Excessive cracked grain in grain tank
Possible Cause Correction
Crop too damp or green. Wait for crop conditions toimprove.
Cylinder speed too fast for cropgrain
cracking but still do a goodjob.
Decrease cylinder speed just enoughto
stop threshing.
Uneven feeding or slugsentering
cylinder.
Refer to section on UNEVEN OR
BUNCHED FEEDING (PG. 16).
Engine not up to correctspeed. See your dealer.
Concave not level. Level concave to cylinder.
Insufficient material entering cylinder.
Increase ground speed for moreintake
of material.
Dented conveyor housings, bent
conveyor shafts or wornconveyor
flighting.
Check each conveyor in thecombine
and header and correct. Remove
dents from conveyor housingsto
achieve adequate clearance with auger.
Straighten or replace bent conveyors.
Repair or replace conveyors with worn
or damaged conveyor flighting.
Concave clearance too close. Increase concave clearance.
Excessive tailings return.
Adjust the cleaning shoe to reduce
tailings. On combines equipped with
optional tailings return, adjust handleto
return tailings to distribution augers.
Grain remains in cage too long. Remove concave fillerbars.
Excessive feed chainspeed.
Check feed chain drive sheave
installation on right-hand end of feeder
countershaft. With grain header, belts
driving off larger sheave diameter. With
corn header, belts driving off smaller
sheave diameter. V/S header drive must
be locked into low speed positionwhen
operating grainheader.
Worn cylinder bars. Replace cylinderbars.
