Lift the header until the center of the rear draper
roller is 14" (356mm) above the ground. This is
an appropriate header operating height.

B) Pickup Operating Height
Depending on field conditions, it may be
necessary to either increase or decrease the
amount of clearance between the teeth and the
ground. Two general symptoms will indicate
that this adjustment is necessary:
a) The pickup leaves material unpicked in the
field. This is an indication that the teeth are
too high.
b) The pickup teeth are wearing quickly or are
picking up dirt and stones. This indicates
that the teeth are set too low.
NOTE: After adjusting tooth height, the
suspension system must be retuned for
optimal performance. See Suspension
Adjustment.
5.3 HOLDDOWN POSITIONING
Hold down position is important to the
performance of the pickup and must be
adjusted according to crop conditions. The
spring wires on the front of the pick up are
designed to keep the swath from forming a
ball or rolling sideways in front of the teeth.
Fiberglass rods hold the swath in contact
with belts and guide the crop under the
auger. Ideally, the spring wires should
touch the top of the swath to keep it in
contact with the pickup teeth. Constant
down pressure on the crop will assist in
pickup performance.
A) Hold down Height Adjustment
The hydraulic hold-down option allows you
to fine tune the hold-down position using the
combines reel height adjust.
NOTE: In the case of plugging the feeder
house, raise the hold-down out of the way
before using the reverser.
DANGER : Lower header to
the ground or engage feeder
house locks, shut-off combine,
remove ignition key, and wait for parts to
stop moving before performing this
adjustment
