Form 169441 36 Revision B
7.12.1.2 Cutting On The Ground
Cutting on the ground is controlled with a
combination of skid shoes, header angle, and
float adjustment, and not with the header lift
cylinders. Having the header "ride" on the skid
shoes allows the float linkage to float header over
obstacles and follow ground contours, rather than
supporting the header with the cylinder.
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. Also, a longer stubble
length helps material dry faster.
Raising the skid shoes and increasing header
angle allows the crop to be “shaved”.
Set up the header as follows:
a. Fully raise the stabilizer wheels, or slow speed
transport wheels if installed. Refer to previous
section.
DANGER
To avoid bodily injury or death from
unexpected start-up or fall of raised machine,
stop engine, remove key and engage lift
cylinder stops before going under machine to
adjust skid shoes or for any reason.
b. Fully raise header, engage lift cylinder stops,
shutoff engine and remove key.
c. Adjust skid shoes to achieve desired cutting
height as follows:
Outer Skid Shoes
1. Remove lynch pin (A) at each skid shoe (B).
2. Hold shoe, and remove pin (C) by
disengaging frame, and then pulling away
from shoe.
3. Raise or lower skid shoe to desired position
using holes in support as a guide.
4. Re-install pin (C), engage in frame, and
secure with lynch pin (A).
Inner Skid Shoes
1. Remove lynch pin (D).
2. Hold shoe (E), and remove pin (F) by pulling
down to disengage frame, and then pulling
away from shoe.
3. Raise or lower skid shoe (E) to desired
position using holes in support (G) as a
guide.
4. Re-insert pin (F), engage in frame, and
secure with lynch pin (D).
d. Check that skid shoes are adjusted to the same
position.
e. Adjust header angle to desired working position
using the machines’ header angle controls. If
angle is not critical, set it to “mid-position”.
f. Check header float as described in the following
section.
7.12.2 HEADER FLOAT
Refer to the M100, M150/M200 or M205 Self-
Propelled Windrower Operator’s Manual to check
and adjust float on windrower headers.
