3.7 Header Operating Variables
Satisfactory function of the header requires making proper adjustments to suit various crops and conditions.
Correct operation reduces crop loss and increases productivity. As well, proper adjustments and timely maintenance will
increase the length of service you receive from your machine.
The variables listed in Table 3.12, page 58 and detailed on the following pages will affect the performance of your header.
You will quickly become adept at adjusting the machine to achieve the results you desire. Most of the adjustments have
been preset at the factory, but the settings can be changed to suit crop conditions.

3.7.1 Cutting Height
The header design allows you to cut the crop above the ground at a desired stubble height or to cut the crop at ground
level with the header on the ground. Cutting height will vary depending on a range of factors including crop type and crop
conditions.
Cutting off the Ground
The stabilizer wheel system is designed to minimize bouncing at the header ends and may be used to float the header to
achieve an even cutting height when cutting above ground level in cereal grains. The system produces an even stubble
height and greatly reduces operator fatigue.
Cutting height is controlled using a combination of the windrower header height control and a stabilizer wheel system (or
stabilizer/slow speed transport wheel system).
The header stabilizer wheel system (or stabilizer/slow speed transport wheel system) is available for all header widths.
If stabilizer wheels are installed, refer to Adjusting Stabilizer Wheels, page 60 to change the wheel position.
If stabilizer/slow speed transport wheels are installed, refer to Adjusting Stabilizer/Slow Speed Transport Wheels, page 58
to change the wheel position.
Adjusting Stabilizer/Slow Speed Transport Wheels
A properly adjusted header will achieve a balance between the amount of header weight carried by the float and the
amount carried by the stabilizer/slow speed transport wheels.
Refer to 3.6.2 Header Settings, page 46 for recommended use in specific crops and crop conditions.
DANGER
To prevent injury or death from the unexpected start-up of the machine, always stop the engine and remove the key
from the ignition before leaving the operator
’
s seat for any reason.
