3. Shims
Note:
When operating in 64 mm (2-1/2 inch)
height of cut or higher, install the axle bolt in the
lower caster-fork hole to prevent grass buildup
between the wheel and the fork. When operating
at heights of cuts lower than 64 mm (2-1/2
inches) and grass buildup is detected, reverse
the machines direction to pull any clippings
away from the wheel/fork area.
5. Remove the tensioning cap from the spindle
shaft and slide the spindle out of the caster arm
(Figure 23).
6. Install 2 shims onto the spindle shaft as they
were originally installed.
Note:
These shims require a level across
the entire width of the cutting units. Slide the
appropriate number of 13 mm (1/2 inch) spacers
(refer to the chart below) onto the spindle shaft
to attain 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
