OPERATION
4.7 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 get the desired results.

4.7.1 Cutting Height
The header is designed to allow a n 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 type of crop,
crop condition, etc.
CuttingOffTheGround
Th
e stabilizing wheel system is designed to m inimize 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 w ith a combination of the combine header height control and a stabilizer wh e el system,
o
r a stabilizer /slo w speed tran sp ort wheel system.
T
he stabilizer wheel system or a stabilizer/slow speed tra n sp ort wheel syste m are only available on 30, 35, and
4
0 ft. headers.
Adjusting Stabilizer/Slow Speed Transport Wheels
The proper setting requires balancing the amount of header weight carried by the float and the stabilizer/slow
speed transport wheels.
1. Raise the header so that the stabilizer wh ee ls are off the ground. Sh ut down eng ine and rem ove the key.
2. Check t hat the float is working properly. Refer to your windrower operator’s manual for instructions.
