Header Shattering of grain ahead of cutter bar Possible Cause Correction Reel speed not coordinated with Change reel speed to coordinate with ground speed. ground speed. Ground speed too fast for condition of Decrease ground speed. crop. Reel height too low. Raise reel.
Page 16
Header Crop bunching on cutter bar Possible Cause Correction Reel too high. Lower reel. Reel too far forward. Set reel back. Reel speed too slow. Increase reel speed. Sticky header pan. Remove dirt, gum or rust. Conveyor too high. Lower header conveyor. Worn conveyor flighting.
Page 17
Header Reel wrapping in tangled and weedy crops Possible Cause Correction Place reel ahead and down. Make sure Incorrect location of pickup reel. reel tines clear the sickle with reel in lowest position. Reel speed too fast. Reduce speed of reel. Pickup reel tines pitched too much to Adjust tine pitch.

Header Header conveyor plugging or material not moving from center of conveyor into front feed chain (Flex Header) Possible Cause Correction Straw retarder clearance from conveyor Adjust straw retarder. flight too great. Adjust reel height. Adjust reel speed Reel not adjusted to provide smooth and flow of material into header flow of material into header conveyor.
Feed Conveyor Feeder chains plugging or wrapping Possible Cause Correction Refer to previous section on HEADER or CONVEYOR PLUGGING (PG. 15) Uneven feed from header. condition for header performance checks. Check feed chain drive sheave installation with grain header belts Improper feed chain speed.
Processor Slugging or overloading of cylinder Possible Cause Correction Adjust engine high idle to proper Engine not up to correct speed. speed. Check condition of belt and replace or clean if it becomes worn or oily. Check Cylinder drive belt slipping. and lubricate gearbox input torque sensor mechanism.

Processor Cylinder vibration Possible Cause Correction Dirt and material stuck to inside of Clean material from inside of cylinder cylinder bars. bars. Place cylinder drive gearbox in neutral and operate cylinder drive through its variable speed range to determine if vibration is still present.
Grain quality Excessive cracked grain in grain tank Possible Cause Correction Crop too damp or green. Wait for crop conditions to improve. Cylinder speed too fast for crop grain Decrease cylinder speed just enough to cracking but still do a good job. stop threshing.
Page 23
Grain quality Grain not threshed from heads or shelled from cob or pod Possible Cause Correction Decrease concave clearance and Concave clearance too great. adjust cylinder speed to prevent cracking. Increase cylinder speed enough to do good job of threshing. Do not increase Cylinder speed too slow.

Grain quality Sieves plugging with straw and chaff Possible Cause Correction Insufficient air blast from cleaning fan. Increase fan choke setting. Consider increasing air, then decrease Sieve opening too wide. sieve opening in 0.06” (1.6 mm) increments. Decrease chaffer opening in 0.06” (1.6 Chaffer opening too wide.
Grain loss Excessive tailings Possible Cause Correction Increase sieve opening in 0.06” (1.6 Insufficient sieve opening. mm) increments. Insufficient air blast from cleaning fan. Increase fan choke setting. Consider increasing air, then decrease Chaffer opening too wide. chaffer opening in 0.06” (1.6 mm) increments.

Grain loss Grain loss over cleaning shoe (cont.) Possible Cause Correction Round end, shallow tooth 1.125” (28.6 mm) shoe spacing - used in all crops except corn. Round end, deep tooth 1.625” (41.3 mm) spacing - generally used in corn but has also been found to provide Incorrect chaffer for crop being desired cleaning in some crops such...
Loss Calculation “Quick check” for combine grain loss Spreading discharge Grain loss calculated per square foot across the entire field. To perform a quick estimate for total grain loss from the combine, count the number of seeds found in a square foot behind the combine. Determine the quantity of loss in at least three places throughout the field to arrive at an average.
Rotor loss Remove the straw spreader, the chaff spreader and raise the shoe tailboard so that shoe and rotor discharge remain separate. Count the grain in a one-foot run of the rotor discharge path, which is 24 inches wide to ensure that all grain is counted. •...
“Advanced” grain loss calculation procedure For the most accurate determination of grain lost through the combine harvester, grain must be “caught” directly from the rotor discharge separately from grain “caught” from the shoe discharge, and weighed.
