Header
Shattering of grain ahead of cutter bar
Possible Cause Correction
Reel speed not coordinated with
ground speed.
Change reel speed to coordinate with
ground speed.
Ground speed too fast for condition of
crop.
Decrease ground speed.
Reel height too low. Raise reel.
Loss of grain heads and cut crop at cutter bar
Possible Cause Correction
Reel not low enough. Lower reel.
Conveyor clearance too high from
header bottom.
Lower conveyor.
Conveyor fingers retracting too early. Adjust fingers close to header bottom.
Cutting with header too high, cutting
stalks too short for proper delivery.
Lower header.
Reel speed too low. Increase speed of reel.
Reel incorrectly positioned on reel
arms.
Position reel closer to header conveyor.
Conveyor flights worn. Replace conveyor flighting.
Guards plugging
Possible Cause Correction
Sickle sections not contacting guards.
Adjust sickle so tips of sickle section
rest lightly on guards.
Missing or worn sickle sections. Replace sickle sections.
Reel not adjusted to provide smooth
flow of material into header conveyor.
Refer to Operator Manual for best
starting position and adjust reel
height, reel speed and reel fore and
aft position for even flow. Straighten or
replace guards.
Guards bent or broken. Straighten or replace guards.
Cutter bar tilted down too much. Tilt cutter bar up.
Bent or twisted sickle. Straighten or replace sickle assembly.
Ground speed too fast. Reduce ground speed.
Skid pads binding (flex header).
Check that skid pad splice brackets are
not binding skid pads.
Flex cutter bar too heavy.
Decrease ground pressure by
increasing spring tension on flex arms
where plugging is occurring.
Flex header height too low.
Move selection to higher cutting
position.
Dirt on skid pads (flex header). Clean dirt off skid pads.
