ADJUSTMENTS
I_iiK eep hands, feet, hair, and loose clothing 1
away from any moving parts on engine or
lawn tractor when making any adjustments
that require engine to be running. DO NOT
carry passengers.
Located beneath the main frame are two v-belts. One v-belt
(lawn tractor drive belt) transmits power to the transaxla, which
in turn transmits power to the rear wheels. The other v-belt
transmits power to the mower blades.
Located on the mower deck is a clutch that disengages power
to the blades and a deck leveling adjustment.
Before any adjustments are made, it is necessary that you un-
derstand the function ofthe brake, clutch, and the brake-clutch
pedal. The pedal disengages the clutch when partially de-
pressed and applies the brake when fully depressed.
Adjustment of the lawn tractor drive belt and brake must be
synchronized so brake does not grab before clutch
disengages. An incorrect adjustment causes brakes to grab or
holdwhile power is being transmitted to the rear wheels. Lawn
tractor will try to move with brake applied; this will cause diffi-
culty when shifting from one speed range or direction to an-
other.
To replace drive belt, you must remove mower deck.
Removal of deck isn't necessary for other adjustments, but if
several adjustments are needed, it will be more convenient ff
deck isremoved.
At no time during the adjustment or repairs _
can the lawn tractor be lifted more than 20
Inches from level position without taking the
following precautions:
1. Remove gasoline from tank and run en-
gine until carburetor is dry.
2. Remove battery. (see BA'rrERY REMOVAL
paragraph in MAINTENANCE section of this
manual.)
3. Remove oil from crankcase.
