Center 3-Point Link Length

Refer to Figure 1-3 on page 9:

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 Cutting Height” on

page 14.
