OPERATION
3.7 Header Operating Variables
Satisfactory function of the header in all s ituations 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 get the desired results.

3.7.1 Cutting Height
The header is designed to allow you to cut the crop above the ground for a desired stubble height or to cut
the crop at ground level w ith the header on the ground. Cutting height will vary, depending on type of crop,
crop condition, etc.
Cutting Off the Ground
Th
e stabilizing wheel system is designed to minimize bouncing at the header ends and may be used to float the
he
aders to achieve an even cutting height when cutting above ground level in cereal grains. The system can
pr
ovide very even stubble height and greatly reduces operator fatigue.
C
utting height is controlled with a combination of t he comb in e header height control and a stabilizer wheel system,
o
r a stabilizer/slow speed transport whe e l system.
I
f stabilizer wheels are installed, refer t o Adjusting Stabilizer Wheels, page 5 4 to change the wheel position.
