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.
25 mm (1 inch) 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 inch diameter holes (Figure 11 &
Figure 12) in each side of the castor forks to 0.50 inch
or 0.516 inch 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
13 mm (1/2 inch) for spacer placement and the
height-of-cut will be 25 to 102 mm (1 to 4 inches).
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 (Figure 11).
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 (Figure 11).

Rear Castor Wheels
1. Remove the tensioning cap from the spindle shaft
(Figure 12).
Note: The rear castor fork assembly does not need
to be removed from the castor arm to change the
height-of-cut.
2. Remove or add the C-shaped spacers at the narrow
portion of the spindle shaft, below the castor arm, to
get the desired height-of-cut (Figure 12). Make sure
that the thrust washers-not the spacers-contact the top
and bottom of the castor arm.
3. Install the tensioning cap to secure the assembly
(Figure 12).
4. Ensure that all four castor wheels are set at the same
height-of-cut.
