2. Position the castor wheel axles in the same holes in
all castor forks. Refer to the chart (Figure 22) to
determine the correct holes for the setting.

mounting holes

mounting holes
Note: When operating at 2-1/2 inch (64 mm)
height of cut or higher, the axle bolt should be
installed in the bottom castor fork hole to prevent
grass buildup between the wheel and the fork.
When operating at heights of cut 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 castor shaft
(Figure 23). and slide the shaft out of the castor
arm. Put 2 shims (1/8 inch [3 mm]) onto the castor
shaft as originally installed. Slide the appropriate
number of 1/2 inch spacers onto the shaft to get
the desired height-of-cut.
Note: The shim washers may be used in any
combination above or below the castor arm hub
as required to achieve the desired height of cut or
deck level.
Refer to the chart (Figure 22) to determine the
combinations of spacers for the setting:
4. Push the castor shaft through the front castor
arm. Install the shims (as originally installed) and
the remaining spacers onto the shaft. Install the
tensioning cap to secure the assembly (Figure 23).
