3. Moving position of MOWER DECK on power unit.
WARNING
DO NOT attempt any maintenance, adjustments or
service with the engine running. Stop engine. Stop
blades. Lock Traction
Disconnect spark plug wires from spark plugs and
secure wires away from spark plugs. Engine and

ADJUSTING CASTER WHEELS

The Caster Wheel Assembly has four (4) 1/2" and one
(1) 1/4" thick spacer. The 1/4" thick spacer always stays
on the stop side of the caster support tube. The 1/2"
thick spacers are used to adjust the cutting height. When
placed above or below Caster Support Tube, they raise
or lower cutting height in 1/2" increments, thus providing
a "Quick-Adjust" method. The deck mounting has to be
changed to correspond to the caster repositioning. Refer
to Section, "ADJUSTING FIXED DECK ATTACHMENT".
1. Remove Retainer Pin from Caster Shaft. See Figure
3.10.

3.11 ADJUSTING BLADE ON CUTTER
SPINDLE
To change cutting height of Blades, move the Spacers from
under the Cutter Housing to above the Cutter Housing
Pulley. Each Spacer moved above the Cutter Housing
Pulley will provide an additional 1/4" of cutting height. DO
NOT put any Spacers below Blade. See Figure 3.12.

NOTE: Changing cutting height of blades does not
change the deck ground clearance. If an undesirable
cutting pattern results, then cutting height adjustment
must be made by adjusting mower deck height and
caster wheels.
Install Blades (Air Lift Up) with retaining hardware as
shown below and tighten to 60 to 75 ft. lbs. of torque. See
