3.8 Header Settings
Satisfactory operation of the disc header in all situations requires making proper adjustments to suit various crops and
conditions.
Correct operation reduces crop loss and increases productivity. Proper adjustments and timely maintenance increases the
length of service of the machine.
The variables listed in the following table and detailed in this manual, affect the performance of the disc header. Most of
the adjustments have been set at the factory, but settings can be changed to suit your crop conditions.

3.8.1 Cutting Height
Cutting height is determined by a combination of the cutterbar angle and skid shoe settings. Adjust cutting height for
optimum cutting performance while preventing excessive build-up of mud and soil inside the disc header, which can lead
to poor crop flow and increased wear on cutting components.
Lowering the skid shoes and decreasing the cutterbar angle increases the cutting height, resulting in higher stubble that
helps material dry faster. This may be desirable in stony conditions to help reduce damage to cutting components.
Raising the skid shoes and increasing the cutterbar angle decreases the cutting height, resulting in a shorter stubble. Refer
to
Adjusting Cutting Height, page 68 .
To choose a header angle that maximizes performance for your crop and field conditions, refer to 3.8.2 Adjusting Cutterbar
Angle, page 69 .
To minimize cutterbar damage, scooping soil, and soil build-up at the cutterbar in damp conditions, the float should be set
as light as possible without causing excessive bouncing. Refer to
3.8.3 Header Float, page 69 .
