OPERATION
4. Remove the lynch pin (A) from each skid shoe (B).
5. Hold the shoe (B) and remove the pin (C) by
disengaging from the frame and pulling away from
the shoe.
6. Raise or lower the skid shoe (B) to achieve the desired
position using the holes in the support (D) as a guide.
7. Reinstall pin (C), engage in frame, and secure with
lynch pin (A).
8. Check that all of the skid shoes are adjusted to the
same position.
9. Check the header fl oat. Refer to
3.7.2 Header Float,
page 55
.
Figure 3.36: Outer Skid Shoe
3.7.2 Header Float
The header fl oat system reduces the ground pressure at the cutterbar allowing the header to more easily follow the
ground and quickly respond to sudden ground contour changes or obstacles.
Header fl oat is indicated on the fl oat indicator (A). The
values 0 to 4 represent the force of the cutterbar on
the ground with 0 being the minimum and 4 being
the maximum.
The maximum force is determined by the tension on the
fl oat module’s adjustable fl oat springs. The tension is
factory-set, but it can be changed to suit fi eld and crop
conditions. Refer to
Checking and Adjusting Header Float,
page 56
.
The FD1 combine header performs best with minimum
ground pressure under normal conditions. Readjust the
fl oat if adding optional attachments that affect the weight
of the header.
Figure 3.37: Float Indicator
1. Set the fl oat for cutting on the ground as follows:
a. Ensure the header fl oat locks are disengaged.
Refer to
Locking/Unlocking Header Float, page
61
.
b. Lower feeder house using the combine header
controls until the fl oat indicator (A) reaches the
desired fl oat value (cutterbar ground force).
Set the fl oat indicator to 2 initially and adjust
as necessary.
