Tailwheel Height Adjustment
Refer to Figure 3-3:
If the front blade tip is set at the desired cutting height and
the back blade tip is at the same height or lower or is
higher than the front blade tip by more than 1", then
tailwheel (#1) must be adjusted up or down as follows:
1. Use tractor’s 3-Point hydraulic control to lift cutter
until tailwheels clear the ground.
2. Remove hex whiz nut (#2) and cap screw (#1).
3. Adjust tailwheel as follows:
• To lower rear blade height, raise tailwheel up.
• To increase rear blade height, lower tailwheel
down.
4. With tailwheels adjusted to the correct height,
replace 1/2"-13 x 4" GR5 cap screw (#1) and hex
whiz nut (#2). Tighten whiz nut to the correct torque.
5. Readjust tractor’s lower 3-Point lift arms as needed.
See “Deck Cutting Height” on page 18.
Center 3-Point Link Adjustment
Refer to Figure 3-4:
1. Lower cutter deck to preset cutting height.
2. Adjust length of center 3-Point link until the center
hitch pin is vertically above the lower 3-Point hitch
pins. The float chain should be hanging loosely when
adjusted correctly. This arrangement allows for
optimum ground contour following performance.
3. Lock center 3-Point link in this position.
NOTE: The lower bolted-on-bushing in the center
hitch is used with a quick hitch attachment.
