Cutterbar Difficulties

Grain shatters ahead of cutterbar

Reel speed not matched to ground speed

Adjust reel speed so that the reel moves the crop evenly.

In standing crops, reel speed should be equal to or slightly less than combine ground speed.

In down and tangled crops, reel speed should be greater than combine ground speed.

Reel set too low

Raise the reel.

Ground speed too fast

Reduce ground speed so that reel does not hit and shatter crops.

Cut crop accumulates and falls ahead of cutterbar; loss of grain heads at cutterbar

Reel set too high

Set reel low enough to sweep material away from the cutterbar, allowing it to be picked up evenly by the auger; extend the cutterbar further forward.

Not enough ledge for crop travel

Extend cutterbar further forward.

Excessive clearance between auger and platform floor

Adjust auger to give 5-10 mm (0.2-0.4 in.) clearance in grain crops and 20-30 mm (0.8-1.2 in.) clearance in crops such as rape and soybeans.

Readjust feeder fingers as appropriate.

Cutting too high, straw too short for proper delivery

Lower cutting platform to cut material long enough for auger to pick it up evenly.

Reel speed too slow

Increase reel speed.

Mat of green material builds up on cutterbar

Cutterbar in extended (front) position

Move cutterbar to middle or retracted position.

Use knife with finely serrated knife sections.
