castor forks, add or remove an equal number of spacers
from the castor forks, and secure the rear chain to the
desired hole.
1. Start the engine and raise the cutting units so that
the height-of-cut can be changed. Stop the engine
and remove the key after the cutting unit is raised.
2. Position the castor wheel axles in the same holes
in all castor forks. Refer to the following chart to
determine the correct holes for the setting.

2. Tensioning cap
3. Spacers
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 14) 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
4. Shims
5. Axle mounting holes
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 16).

6. Mount the height-of-cut chains to the desired
height-of-cut hole (Figure 17) with the clevis pin
and hairpin cotter.
