2. Spacers
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.
