or plug up with trash and
then push dirt.
Insufficient support for
header.
Excessive gap between
top of front of draper and
cutterbar.
Reel fingers (steel) bent
and hook plants from crop
flow on drapers.
Dirt accumulation on end
of fingers prevent plants
dropping off fingers onto
drapers.
Tire tracks or row crop
ridges.
Rolling land along length
of field.
Solution
Increase float.
Consider installing
optional stub guards.
Tip: Experiment with a
few guards on a section of
cutterbar to compare the
performance of the two
different styles of guards.
Re-adjust float to make
header lighter.
Decrease header angle
with lift cylinders.
Shorten the center-link.
Install stub guard kit.
Install center skid shoes
on header.
Adjust front deck supports
to obtain proper clearance
between cutterbar and
draper.
Raise header fully at each
end of field or as required
and shift decks back and
forth to help clean out
cutterbar.
Straighten fingers (steel).
Raise reel.
Adjust reel fore and aft
location to move fingers
out of the ground.
Cut at angle to ridges or
crop rows to allow knife
and guards to clean out
better.
Cut at 90° to undulations,
provided knife floats
across without digging in.
