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.
