3. Shims
Note: When operating in 2-1/2 inch (64 mm) height
of cut or higher, the axle bolt must be installed in the
lower castor fork hole to prevent grass buildup between
the wheel and the fork. When operating in height
of cuts lower than 2-1/2 inches (64 mm) and grass
buildup is detected, reverse the machines direction to
pull any clippings away from the wheel/fork area.
3. Remove the tensioning cap from the spindle shaft
(Figure 16) and slide the spindle out of the castor arm.
Put the 2 shims (1/8 inch [3 mm]) onto the spindle
shaft as they were originally installed. These shims are
required to achieve a level across the entire width of
the cutting units. Slide the appropriate number of 1/2
inch spacers (refer to the chart below) onto the spindle
shaft to get the desired height-of-cut; then slide the
washer onto the shaft.
Refer to the following chart to determine the
combinations of spacers for the setting:

4. Push the castor spindle through the front castor arm.
Install the shims (as they were originally installed) and
the remaining spacers onto the spindle shaft. Install the
tensioning cap to secure the assembly.

5. Remove the hairpin cotter and clevis pin securing the
height-of-cut chains to the rear of the cutting unit
(Figure 18).

6. Mount the height-of-cut chains to the desired
height-of-cut hole (Figure 19) with the clevis pin and
hairpin cotter.
Note: When using 1 inch (25 mm), 1-1/2 inch (38
mm), or occasionally 2 inch (51 mm) height-of-cut,
move the skids and gage wheels to the highest position.
Wing Cutting Units
To adjust the height-of-cut on the side cutting units, add
or remove an equal number of spacers from the castor
forks, position the castor wheel axles in the high or low
height-of-cut holes in the castor forks, and secure the pivot
arms to the selected height-of-cut bracket holes.
1. Position the castor wheel axles in the same holes in all
of the castor forks (Figure 20 and Figure 22). Refer to
the following chart to determine the correct hole for
the setting.
2. Remove the tensioning cap from the spindle shaft
(Figure 20) and slide the spindle out of castor arm. Put
the two shims (1/8 inch [3 mm]) onto spindle shaft as
they were originally installed. These shims are required
to achieve a level across the entire width of the cutting
units. Slide the appropriate number of 1/2 inch spacers
