Center 3-Point Link Adjustment
Refer to Figure 1-3 on page 9:
1.
Lower cutter deck to the nominal cutting height.
2.
Adjust length of center 3-point link so that the upper
pivot hitch rest at a slight downhill position. This
arrangement allows for optimum ground contour
following performance.
3.
Lock center link in this position once correct length is
achieved.
4.
The second set of holes on the upper pivot hitch
should be used when tractor’s center 3-point link is
too short.
Tailwheel Height Adjustment
Refer to Figure 3-3:
If deck slope is slightly lower at the front than at the back
and cutting height is not at the desired height, then the
tailwheel must be adjusted up or down as follows:
1.
Use tractor’s 3-point hydraulic control to lift cutter
until the tailwheel clears the ground.
2.
Remove carriage bolt (#1) and 5/8" flange nut (#2).
3.
Adjust tailwheel as follows:
•
To lower cutting height, adjust tailwheel up.
•
To increase cutting height, adjust tailwheel down.
4.
With tailwheel adjusted to the correct height, replace
5/8" x 1 1/2" long carriage bolt (#1) and 5/8" flange
nut (#2). Tighten flange nut to the correct torque.
5.
Readjust tractor’s lower 3-point arm height as
needed. See section titled “Deck Leveling From Front
to Rear” on page 15.
