SECTION 3 - OPERATING INSTRUCTIONS
3.8 ADJUSTING CUTTING HEIGHT (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
Before making any cutting height adjustments, move
ignition key to STOP position, remove key from key
switch, close fuel shut-off valve and disconnect
spark plug wire(s) from spark plug(s).
3.9 ADJUSTING CASTER WHEELS
The Caster Wheel Assemblies have four (4) 1/2" and
one (1) 1/4" thick Spacer. When placed above or below
Caster Support Tube, the Operator can raise or lower
the cutting height in 1/2" increments, thus providing a
"Quick-Adjust" method. The deck mounting has to be
changed to correspond with the Caster repositioning as
described in ADJUSTING FIXED MOWER DECK
ATTACHMENT.
1. Remove the Retainer Pin from Caster Shaft. See
Figure 3.12.

3.10 ADJUSTING BLADE ON CU'R'ER 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.
NEVER 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.
