3.10.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 3.10.

3.11 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 3.12.

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. of torque. See Figure 3.13.
