Operation
Note:
Determine the left and right sides of the
machine from the normal operating position.
CAUTION
If you leave the key in the ignition switch,
someone could accidently start the engine
and seriously injure you or other bystanders.
Remove the key from the ignition before you
do any maintenance.
Adjusting the Height of Cut
The height of cut is adjustable from 25 to 127 mm (1
to 5 inches) in 13 mm (1/2 inch) increments. To adjust
the height of cut, position the castor wheel axles in
the upper or lower holes of the castor forks, add or
remove an equal number of spacers from the castor
forks and secure the height of cut collar to the desired
holes in the height of cut rod.
1.
Start the engine and raise the cutting unit off the
floor 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 both castor forks. Refer to
Figure 7
to determine the correct holes for the
setting.

Note:
When operating in 64 mm (2–1/2 inch)
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 64
mm (2–1/2 inch) 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

castor arm. Put the 2 shims (1/8 inch) 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 onto
the spindle shaft to get the desired height of cut;
then slide the washer onto the shaft.

4.
Push the castor spindle through the 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.
