Cutting Height; Adjusting The Skid Shoe Height - MacDon R85 Operator's Manual

6.7 Cutting Height

Cutting height is determined by a combination of the angle of the cutterbar/header and the skid shoe settings. Cutting
height should be adjusted for optimum cutting performance without excessive mud build-up inside the header that
can lead to poor crop flow and increased wear on cutting components. Choose an angle that maximizes performance
for your crop and field conditions. Refer to
Optional adjustable skid shoes are also available to provide different cutting heights. Refer to:
•
9.1 Options and Attachments – Kits, page 163
•
Adjusting Gauge Roller Height

6.7.1 Adjusting the Skid Shoe Height, page 84
Lowering the skid shoes or decreasing header angle increases the cutting height. This may reduce damage to
cutting components in stony conditions. Also, a longer stubble length helps material dry faster.
Raising the skid shoes and increasing header angle allows the crop to be cut lower.
To minimize damage to cutterbar components, scooping soil, or soil build-up at the cutterbar in damp conditions, set
header float as light as possible without excessive bouncing.
A light float setting may require reduced ground speeds to avoid excess bouncing and a ragged cut.

DANGER
To avoid bodily injury or death from unexpected start-up or fall of raised machine: stop engine, remove
key, and engage safety props before going under machine for any reason.
1. Raise header fully, stop engine, and remove key.
2. Engage header safety props.
3. Remove bolts (A).
4. Raise or lower skid shoe (B).
5. Reinstall bolts (A).
6. Repeat for skid shoe at opposite end of header.
7. Check header float as described in
page 71.
8. Adjust header angle to desired working position using
the machine's header angle controls. If angle is not
critical, set it to mid-position. Refer to
Angle, page 83.
