Cutting Height - MacDon R85 Operator's Manual

6.10.7 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 allowing excessive
build-up of mud and soil 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.
Section 6.11.6 Header Angle.
Optional adjustable skid shoes are available to
also provide different
described below:
•
Lowering the skid shoes or decreasing
header angle increases the cutting
height. This may be desirable in stony
conditions, to reduce damage to cutting
components.
length helps material dry faster.
•
Raising the skid shoes and increasing
header angle allows the crop to be
"shaved".
To minimize damage to cutterbar components,
scooping soil, or soil build-up at the cutterbar in
damp conditions, header float should be set as
light as possible without causing excessive
bouncing. When the float setting is light, it may
be necessary to use a slower ground speed to
avoid excessive bouncing and leaving a ragged
cut.
Set up the header as follows:
DANGER
To avoid bodily injury or death from
unexpected start-up or fall of raised
machine; stop engine, remove key and
engage header lift cylinder stops before
going under machine for any reason.
a. Raise header fully, stop engine, and remove
key.
b. Remove lynch pin and remove adjuster pin (A)
from one side of skid shoe.
c. Hold skid shoe and remove lynch pin and
adjuster pin (A) from other side. Position shoe
at desired position and reinstall adjuster pins
(A). Secure with lynch pins.
d. Repeat for skid shoe at opposite end of header.

f. Adjust header angle to desired working position
using the machines' header angle controls. If
angle is not critical, set it to mid-position. Refer
