Cutting Platform

Symptom Problem Solution

Shattering of Grain Ahead of Cutterbar

Reel speed not matched to ground speed, causing crop to be overly disturbed before it is cut.

Adjust reel speed to match with ground speed so reel moves crop evenly. Reel should turn slightly faster than ground speed.

Reel is positioned too low.

Raise reel.

Ground speed is too fast for the conditions of the crop.

Slow down ground speed so that reel will not hit crop, causing it to shatter.

Cut Crop Building Up and Falling from Front of Cutterbar or Loss of Grain Heads at Cutterbar

Reel not adjusted low enough for good delivery of cut crop to the belts.

Set reel low enough to sweep material from the cutterbar.

Reel too far forward.

Move reel closer to cutterbar.

Cutterbar belt angle to steep.

Use tilt adjuster at the center of the platform to adjust angle of cutterbar.

Ragged and Uneven Cutting of Crop

Feeder house lower shaft not at the recommended speed.

Check basic speed of the combine. (see Operator's Manual)

Knife dull.

Replace knife.

Cutterbar plugged with material.

Adjust reel to sweep material off cutterbar.

Knife sections damaged.

Replace damaged sections.

Integral knife hold-downs adjusted loose.

Readjust hold-downs to the recommended clearance.

Too Much Material Entering Combine

Cutting too low, trying to get all down and tangled crops.

Cut higher, use pickup reel in down or tangled crops.

Excessive Vibration of Cutting Parts

Feeder house lower shaft not at recommended speed.

Check basic speed of combine. (see Operator's Manual)

Variable speed feeder house is too fast.

Slow variable speed feeder house.

Symptom Problem Solution

Excessive Knife Drive Belt Vibration

Knife head to knife drive connection loose.

Inspect connector, replace spacer ring, reset alignment and tighten properly. (see Service section).

Heavy knife loads.

Inspect knife sections and guards for worn cutting edges. Replace as needed.

Reel Wrapping in Tangled and Weedy Conditions

Slat reel not delivering crop.

Install a pickup reel.

Incorrect reel location.

Adjust reel forward and down.

Reel speed too fast.

Slow reel until crop flows smoothly onto belts.

Reel Carrying Around Straw

Reel speed too fast.

Slow reel speed. Reel should turn slightly faster than ground speed.

Reel height too low.

Raise reel to reduce the amount of straw gathered by the reel.

Pickup fingers pitched too much.

Reduce finger pitch.

Uneven or Bunched Feeding of Crop to Feeder House

Incorrect feed drum finger timing.

Adjust finger timing.

Incorrect feed drum height.

Adjust drum height.

Feeder house conveyor chain too slow.

Change to large sprocket on right-hand side of lower feeder house drive shaft.

Feeder house conveyor chain too loose.

Adjust tension (see Combine Operators Manual).

Feeder house drum lower stops set too high.

Adjust lower stops. (see Combine Operators Manual) Remove optional feeder house closure strips.

Feeder house drive chain too loose

Adjust tension (see Combine Operators Manual)

Symptom Problem Solution

Crop Material Back-feeding at Feed Drum

Wrong finger timing.

Adjust finger timing.

Draper feed drum wrong height.

Adjust drum height.

Feeder house conveyor chain too slow.

Change to large sprocket on right-hand side of lower feeder house drive shaft.

Combine not removing material from platform.

Lower feeder house front drum (see Combine Operators Manual).

Set drag chain to high speed (see Combine Operators Manual).

Properly tension drag chain and drive chain (see Combine Operators Manual).

Set combine feed accelerator to high speed (see Combine Operators Manual).

Crop Material Pulled Underneath Side Belts from Center Belt Area

Cutterbar Angle set too shallow moving side belts too close to center belt.

Increase cutterbar and side delivery belt angle to move side belts away from center belt area.

Belt speed too slow allowing buildup on sides of the center belt.

Increase belt speed.

Side belts too close to center belt.

Increase vertical top beam spacing by shortening vertical top beam height screws (see Adjustments - Suspension and Leveling section).

Symptom Problem Solution

Crop Material Pulled Underneath Center Belt

Feed drum finger pitch incorrect.

Advance feed drum timing casting.

Fingers too far away from belt and floor area.

Lower drum (see Adjustments - Feeding Related section)

Excessive crop material at side of center belt.

Reposition side belts and increase side belt speed (see Adjustments - Feeding Related section).

Insufficient drop from side belts to center belt.

Increase clearance between side belt and center belt by increasing tilt of platform and/or shortening vertical top beam height screws (see Adjustments - Suspension and Leveling section).

Crop material under center draper building up at sump pan.

Remove sump pan.

Center belt slipping.

Increase belt tension.

Belt splice joint too high.

Trim off excessive material.

Friction of crop on feed floor surface is too high.

Remove paint or rust underneath feed drum to provide a smooth surface for crop flow.

Combine not removing material from platform.

Lower feeder house front drum (see Combine Operators Manual).

Set drag chain to high speed (see Combine Operators Manual).

Properly tension drag chain and drive chain (see Combine Operators Manual).

Set combine feed accelerator to high speed (see Combine Operators Manual).
