SECTION 9. OPERATION
Form 169006 89 Revision D
9.11.1 Header Operating Variables
Satisfactory function of the header in all situations
requires making proper adjustments to suit
various crops and conditions.
Correct operation reduces crop loss and allows
cutting of more acres. As well, proper
adjustments and timely maintenance will increase
the length of service you receive from the
machine.
The variables listed below and detailed on the
following pages will affect the performance of the
machine. You will quickly become adept at
adjusting the machine to give you the desired
results.

9.11.2 Cutting Height
The D and FD Series of draper headers are
designed to allow an Operator to cut the crop
above the ground for a desired stubble height, or
to cut the crop at ground level with the header on
the ground.
Cutting height will vary, depending on factors
including whether windrowing or straight-cutting,
type of crop, etc.
9.11.2.1 Cutting Off The Ground
Cutting height is controlled with a combination of
header lift cylinder adjustment and a stabilizer
wheel system, or a stabilizer/slow speed transport
wheel system. Both systems are only available
on 30, 35, 40, and 45 FT headers.
The stabilizing wheel system in both options is
designed to minimize bouncing at the header
ends, and may be used to “float” the headers to
achieve an even cutting height when cutting
above ground level in cereal grains.
The system can provide very even stubble height
and greatly reduced operator fatigue.
The proper setting requires ‘balancing’ the
amount of header weight carried by the main float
and the stabilizer wheels.
CAUTION
Stop engine, and remove key from ignition
before leaving Operator's seat for any reason.
A child or even a pet could engage an idling
machine.
a. Raise the header so that the stabilizer wheels are
off the ground. Shut down engine, and remove
the key.
b. Check that the main float is working properly.
See Section 9.11.3 Header Float.
c. Set up the stabilizer wheels, if installed, as
follows: Otherwise, proceed to step d. on next
page.
IMPORTANT
Do not use the stabilizer wheel system
for header height control if your header
was manufactured prior to 2007. This
would result in damage to the wheel
suspension system.
CAUTION
Handle may be under tension, especially
when the wheels are on the ground. Raise
header so that wheels are off the ground
before making adjustments.
1. Support wheel weight by lifting slightly with
one hand on handle B. Pull up on handle (A)
to release lock.
2. Lift wheel with handle (B) and engage
support channel into center slot (C) in upper
support.
3. Push down on handle (A) to lock.
