Height of Cut Adjustment (Fig. 6, 7, 8)
The height of cut is adjustable from 1 to 4 inches in
1/2 inch increments, by adding or removing an equal
number of spacers on the front and rear caster forks.
The height of cut chart below gives the combinations of
spacers to use for all height of cut settings.

NOTE: A more optimum cutting appearance in the 1 inch
height of cut setting can be achieved by lowering the
rear of the cutting unit. Do this by relocating the rear
caster wheel axles in the upper holes of the caster forks.
Install the axles into the lower caster fork holes for
settings above 1 inch.
IMPORTANT: The rear caster wheel mounting hole
in use must be towards the rear of the deck. This is
necessary to provide adequate clearance between
the caster wheel and the mechanical door. If neces­
sary, the caster fork assembly should be removed
from the square tube and turned around so that the
mounting hole with the axle through it is toward the
rear. The caster wheel grease fittings should always
face outward.
IMPORTANT: Do not attempt to cut off more than
one inch of the grass blades in the one (1) inch
height of cut setting with the rear of the cutting unit
lowered, as this may cause the engine to labor
excessively.
1. Start the engine and raise cutting unit so height of cut
can be changed. Stop engine after cutting unit is raised.
2. Squeeze back of wire and rotate wire on lynch pin.
Pull pin out of caster spindle. Slide spacers onto the
caster spindle to get desired height of cut. Then slide
washer onto caster shaft (front only).
3. Push caster shaft through caster arm. Slide any
remaining spacers onto spindle. Install lynch pin to
retain parts in place. Always have the same number of
spacers on each caster when adjusting height of cut.
