Cross auger wraps crop. Crop susceptible to
wrapping. e.g. flax • Remove auger beaters.
• Remove cross auger. 24
Crop backs up on feed
draper. Fluffy crop not aggress-
ively fed by auger. Extend auger beaters. 24
Heavy crop plugging
between auger & feed
draper Raise auger. 24
Crop back feeds on center
feed draper Excessive clearance
from combine feed drum
to adapter feed draper. Add feeder chain links as
necessary to achieve less
clearance between feed
drum and feed draper.
Ensure a 1-3” (25-75 mm)
clearance between the feed
drum and feed auger.
(Drum floated up). *
Side drapers back-feed. Side drapers running too
slow in heavy crop. Increase draper speed. 14
Side drapers improperly
set with respect to feed
draper. Center side draper drive
rollers over feed draper side
deflectors. ***
Crop is thrown across
opening and under opposite
side draper. Side drapers running too
fast in light crop. Reduce draper speed. 14
Excessive overlap of
feeder draper. Center side draper drive
rollers over feed draper side
deflectors. ***
Hesitation in crop flow at
feeder house. Rear deflector fins set
too wide. Set fins approximately 1/2"
(13 mm) inside feeder
house opening. 30
FLOTATION
Combine feeder housing
pushes dirt when trying to
pick up down crop. Feeder housing lowered
too far, eliminating
header float. Raise feeder housing until
float linkage bottoms,
change header to steeper
angle to pick up down crop. 16
Float too light, header
legs do not rest on stops. Adjust to heavier float. 15
Cutterbar does not float or
pushes dirt. Float set too heavy. Adjust to lighter float. 15
Float lockout not
disengaged. Raise header, disengage
float lockout. 7
Excessive vibration of
adapter and header. Feed pan clearance to
cutterbar is incorrect. Adjust feed pan clearance. 9
