Before Operating
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.
Caution
Checking the Lubricant in the
Gear Box
The gear box in designed to operate on SAE 80–90 wt. gear
lube. Although the gear box is shipped with lubricant from
the factory, check the level before operating the cutting
unit.
1. Position the machine and cutting unit on a level surface.
2. Remove the dipstick/fill plug from the top of the gear
box (Fig. 9) and make sure that the lubricant is between
the marks on the dipstick. If the lubricant level is low,
add enough lubricant until the level is between the
marks.

Adjusting the Height-of-Cut
The height-of-cut is adjustable from 1 to 5 inches (25 to
127 mm) in 1/2 inch (13 mm) 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 11 to determine the correct
holes for the setting.
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
(Fig. 10) and slide the spindle out of the 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.
Refer to figure 11 to determine the combinations of spacers
for the setting.
