SECTION 3 - OPERATING INSTRUCTIONS
3.10 CUTTING HEIGHT ADJUSTMENT
(Fixed Decks)
Mower has three methods of adjusting cutting height:
1. Moving position of BLADE on cutter spindle shaft.
2. Moving position of CASTER WHEEL on support.
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. Latch Traction Lock Levers. Remove key.
Disconnect spark plug wires from spark plugs and
secure wires away from spark plugs. Engine and
components are HOT. Avoid serious burns by
allowing all parts sufficient time to cool before
working on machine.
3.11. ADJUSTING CASTER WHEELS
The Caster Wheel Assembly has four (4) 1/2" and one
(1) 1/4" thick spacer. 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 as described in ADJUSTING
FIXED DECK ATTACHMENT.
3.12 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 3.14.

3.12.1 ADJUSTING BLADE ON CUTTER SPINDLE
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.-Ibs. See Figure 3.15.
