7.9.1.2 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.
NOTE
Skid shoes are standard equipment
on the D65 header.
Having the header ride on the skid shoes allows
the float linkage to float the header over
obstacles and follow ground contours, rather
than supporting the header with the cylinders.
Lowering the skid shoes or decreasing the
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 the
header angle allows the crop to be shaved.
Refer to Section 7.8.1 Header Settings for
recommended skid shoe positions in specific
crops and crop conditions.
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,
shut off 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 machine’s header angle controls. If
angle is not critical, set it to mid-position.
f. Check header float as described in the following
Section 7.9.2 Header Float.
