6. Mount the height-of-cut chains to the desired
height-of-cut hole (Figure 25) with the clevis pin
and hairpin cotter.
Figure 25
Note: When mowing at height-of-cuts below
2–1/2 inches (51 mm), move the skids, gage wheels
and rollers to the highest holes.
7. To attain the 5 to 6 inch (102 to 153 mm) height of
cut settings, remove the mounting bolts securing
the deck hanger brackets to the height of cut castor
arms and remount the deck hanger brackets to the
height of cut castor arms using the lower set of
holes (Figure 26).

Side Cutting Units
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 chart (Figure 27)
to determine the correct holes for the height of
cut setting.
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 spindle
shaft (Figure 28) and slide the castor shaft out of
the castor arm. Put 2 shims (1/8 inch [3 mm]) onto
the 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.
