Cutting Height Adjustment, Fixed Decks | Snapper SPLH141KWE, SP400

SECTION 3 - OPERATING INSTRUCTIONS

3.8 CUTTING HEIGHT ADJUSTMENT

(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

DO NOT attempt any maintenance, adjustments or service with the engine running. Stop engine. Stop blades. Latch Traction Controls in neutral. Move Speed Control lever to SLOW. Remove key. Disconnect spark plug wires from spark plugs and secure wires away from spark plugs. Engine and components are HOT. Avoid serious burns by allowing all parts sufficient time to cool before working on machine.

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 Section “ADJUSTING FIXED MOWER DECK ATTACHMENT”.

1.Remove the Retainer Pin from Caster Shaft. See Figure 3.12.

3.10 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 3.14.
