Revision A
3.7 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.

Conditioner Settings 3.8 Conditioner, page 54
3.7.1 Cutting Height
Cutting height is determined by a combination of the cutterbar angle and the optional skid shoe or gauge roller settings.
Adjust the cutting height for optimum cutting performance and to prevent build-up inside the disc header. Excessive build-
up of mud and soil can lead to poor crop flow and increased wear on cutting components.
Optional adjustable gauge rollers and skid shoes are available to provide different cutting heights. For instructions, refer to:
•
Adjusting Skid Shoe Height, page 48
•
Adjusting Gauge Roller Height, page 49
Lowering the skid shoes (or gauge rollers) 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 (or gauge rollers) and increasing also the cutterbar angle decreases the cutting height, resulting in a
shorter stubble.
To choose a header angle that maximizes performance for your crop and field conditions, refer to 3.7.2 Adjusting Cutterbar
Angle, page 52 .
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. For instructions, refer to
3.7.3 Header Float, page 52 .
