Before Operating
Checking the Lubricant in the
Gear Box
The gear box is 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 1-1/2 to 4-1/2 in. (38 to
114 mm) in 1/2 inch (13 mm) increments, by adding or
removing an equal number of spacers from the front and
rear castor forks. The height-of-cut chart below gives the
combinations of spacers to use for all height-of-cut settings.

Start the engine and raise the cutting unit so that the
height-of-cut can be changed. Stop the engine after the
cutting unit is raised.
A 1 in. (25 mm) height-of-cut can be attained by modifying
the castor forks as follows:
1. Remove the front and rear castor forks from the cutting
deck and remove the wheels from the forks.
2. Drill out the 0.438 in. diameter holes (Fig. 10 and 11) in
each side of the castor forks to 0.50 in. or 0.516 in.
diameter.
3. Using the new holes, install the castor wheels on the
forks and install the forks on the deck.
Note: The height-of-cut decal will now be off by 1/2 in.
(13 mm) for spacer placement and the height-of-cut will be
1 to 4 in. (25 to 102 mm).
Front Castor Wheels
1. Remove the tensioning cap from the spindle shaft and
slide the spindle out of the front castor arm. Remove the
washer from the spindle shaft. Slide the spacers onto the
spindle shaft to get desired the height-of-cut, then slide
the washer onto the shaft (Fig. 10).
2. Push the castor spindle through the front castor arm,
install the other thrust washer and remaining spacers
onto the spindle, and install the tensioning cap to secure
the assembly (Fig. 10).
