SECTION 8: MAKING ADJUSTMENTS
WARNING: Disconnect the spark plug
wire(s) and ground against the engine
before performing any adjustments,
repairs or maintenance.
LEVELING THE DECK
The sides of the deck should be the same distance from
the ground. The front of the deck should be 1/4" to 3/8"
lower than the rear of the deck. If adjustment is
required, refer to “Leveling the Deck” in Assembly
Instructions.

SPEED CONTROL ADJUSTMENT
(See Figure 21)
NOTE:
When operating the unit initially or after
replacing the belts, there will be little difference
between the highest two speeds until after the belts
have gone through a break-in period and have seated
themselves into the pulleys.

control links as follows. (A 3/4" shim or suitable spacer
is required.)

After engine stops completely, release the clutch-
brake pedal.
•
Remove the transmission cover by removing the
parking brake knob, shift knob and two truss
machine screws.

variable speed torque bracket by removing the
cotter pin and flat washer.
