Troubleshooting
Header
Ragged and uneven cutting of crop
Possible Cause Correction
Cutting mechanism not operating at
recommended speed.
Check basic speed of combine and
check header drives.
Reel speed too slow for ground speed. Increase reel speed.
Reel height too high. Lower reel.
Reel position is either too far forward or
too far back on reel arms.
Adjust reel position so reel bats hold
grain leaning slightly into sickle.
Header not level. Level header.
Guards are bent or broken. Straighten or replace guards.
Upper lips of guards bent causing poor
shearing action.
Adjust upper lips of guards so they are
parallel to lower shear edge of guard.
Sickle not contacting guards.
Adjust sickle so tips of sickle sections
rest lightly on guards.
Sickle hold down clips worn or not
adjusted properly.
Replace worn hold down clips and
adjust clips.
Too much fore and aft looseness
between sickle back and guards.
Adjust wear plates.
Bent or twisted sickle. Straighten or replace sickle assembly.
Ground speed too fast. Reduce ground speed.
Flex cutter bar hanging up.
Check flex arms, filler panels (at ends
of headers) and stabilizers for freedom
of movement and correct any binding.
Flex header height sensor on rockshaft
not set the same.
Readjust sensor as outlined in header
Operator Manual.
Rockshaft binding (flex header) Free rockshaft.
Insufficient ground pressure from flex
cutter bar.
Increase ground pressure by
decreasing spring tension on flex arms.
Flex cutter bar tilted up too much at the
front.
Tilt cutter bar down so skid pads are
parallel to the ground.
Intermittent signal for automatic header
height control flex header.
Clean corrosion and paint from
contacts on switches. Check for good
connectiion at harness disconnects.
Check for broken wires in harness.
