Height of Cut Adjustment
The height–of–cut is adjustable from 1–1/2 to 4–1/2 in-
ches in 1/2 inch 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 combina-
tions of spacers to use for all height–of–cut settings.
2. Remove or add ”C” shaped spacers at the narrow
portion of the spindle shaft, below castor arm, to get de-
sired height–of–cut. Make sure thrust washers – not the
spacers – contact the top and bottom of the castor arm.
3. Install tensioning cap to secure assembly .

Note: 1” height–of–cut can be attained by modifying the
castor forks as follows:
A. Remove front and rear castor forks from cut-
ting deck and remove wheels from forks.
B. Drill out .438” dia. holes (Fig. 1 & 2) in each
side of castor forks to .500” or .516” dia.
C. Using new holes, reinstall castor wheels to
forks and install forks to deck.
Note: Height–of–cut decal will now be off by 1/2”
for spacer placement and height–of–cut will be 1”
to 4”.
Front Castor Wheels
1. Remove tensioning cap from spindle shaft and slide
spindle out of front castor arm. Remove washer from
spindle shaft. Slide spacers onto spindle shaft to get de-
sired height–of–cut, then slide washer onto shaft.
2. Push castor spindle through front castor arm, install
other thrust washer and remaining spacers onto spindle
and install tensioning cap to secure assembly .
Rear Castor Wheels
1. Remove tensioning cap from spindle shaft.
Note: Rear castor fork assembly does not need to be re-
moved from castor arm to change height–of–cut.
