3.9 Header Operating Variables
Satisfactory function of the header requires making adjustments to suit various crops and conditions.
Correctly adjusting the header reduces crop loss and speeds harvesting. Proper adjustments, along with timely
maintenance, will also increase the service life of the header.
The variables listed in Table 3.15, page 120 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 settings below have
been configured at the factory, but the settings can be changed to suit various crops and harvesting conditions.

3.9.1 Cutting off Ground
The header
’
s design allows you to cut crop above the ground, which results in stubble being cut to a uniform height. Follow
these recommendations when configuring the header to cut above ground level.
When cutting above ground level:
•
Use the stabilizer wheels on the header (if this optional component is installed) to set the cutting height. 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.
NOTE:
The header wings must be locked when using the stabilizer wheel system.
•
The ContourMax
™
contour wheels provide consistent cutting height information back to the header so it can flex,
maintain accurate and consistent cutting height, and still use the combine
’
s auto height control seamlessly. The contour
wheels contact the ground, which allows the cutterbar to remain at a fixed height above the ground even through
rolling contours. There is no adjustment necessary to the factory auto height control settings.
NOTE:
The header wings must be locked when using the ContourMax
™
system.
