SECTION 3 - OPERATING INSTRUCTIONS
3.8 CUTTING HEIGHT ADJUSTMENT
(Fixed Decks)
The Mower has three methods of adjusting cutting
height listed as follows:
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 Controls in neutral. Move
Speed Control lever to SLOW. Remove key.
Disconnect spark plug wires from spark plugs and
secure wires away from spark plugs. Engine and
components are HOT. Avoid serious burns, allow all
parts to cool before working on machine.
3.9 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 the Retainer Pin from Caster Shaft. See
Figure 3.12.

3.10 ADJUSTING BLADE ON CUTTER PINDLE
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.

NOTE: Changing the 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 70-80 ft. Ibs.
See Figure 3.15.
