3.10CUTTING 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”.

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.

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.
