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. Lock Traction 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, allow all
parts 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. 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
3.11.
FIGURE 3.11
2.
Lift Caster Support while adding or removing bottom
spacer. See Figure 3.12.
NOTE:
Remove (or add) spacers by rotating slots to
align with flat area on caster shaft.
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
Figures 3.13 and 3.14.
FIGURE 3.12
FIGURE 3.13
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. See Figure 3.14.
