BELT-DRIVE WALK BEHIND MOWER
30
ADJUSTMENTS
Note: Disengage PTO, shut off engine, wait for all
moving parts to stop, engage parking brake, and
remove key before servicing, cleaning, or making
any adjustments to the unit.
WARNING
POTENTIAL FOR SERIOUS INJURY
Certain procedures required the vehicle engine
to be operated and the vehicle to be raised off
of the ground. To prevent possible injury to the
servicing technician and/or bystanders, insure
the vehicle is properly secured.
CAUTION
Raising the mower for service or
maintenance relying solely on mechanical
or hydraulic jacks could be dangerous. The
mechanical or hydraulic jacks may not be
enough support or may malfunction
allowing the unit to fall, which could cause
injury.
Do Not rely solely on mechanical or
hydraulic jacks for support. Use adequate
jack stands or equivalent support.
TRANSMISSION DRIVE BELT TENSION
Adjust sliding idler to obtain 1/2" belt deflection
midway between engine and transmission pulleys.
DRIVE WHEEL BELT TENSION
Self adjusting.
MOWER DECK DRIVE BELT TENSION
Adjust eye bolt to obtain spring length of 3 1/2" to 3
3/4" measured over 19 coils (1/32" gap between
coils).
STEERING LEVER ADJUSTMENT
Steering characteristics are affected by the
relationship between the drive wheel clutching and
braking positions. The greater the distance the
steering lever must travel between these two
positions, the slower the turning response time will
be, resulting in increased operator effort.
Remove the hairpin cotter pin from the 5/16" swivel
in the engagement bracket and adjust the effective
length of the steering lever rod so that the end of
the steering lever is 2” - 3" below the handlebar as
in Fig. 1 on page 18. Keep in mind that the smaller
this dimension, the shorter the distance between
clutching and braking functions.
Reinstall the 5/16" steering rod swivels and secure
with the hairpin cotter pins.
PARK BRAKE ADJUSTMENT
If the parking brakes do not hold securely,
adjustment is required:
1. Remove the hairpin cotter pin from the 3/8"
swivel at the top end of the brake adjusting rod.
2. Shorten the effective length of the brake
adjusting rod by turning the 3/8" swivel until the
desired amount of braking force is obtained.
3. Reinstall the 3/8" brake rod swivel and the
hairpin cotter pin.
FORWARD TRACKING ADJUSTMENT
Although there is no actual adjustment for forward
travel tracking, if the machine tends to turn right or
left while traveling forward on level terrain, you
should:
1. Check tire pressure to ensure equal pressure
between drive tires. The correct pressure for
the drive tires is 12 psi.
2. Check adjustment of steering levers and park
brakes.
3. Check and replace worn wheel drive belts
(must be replaced in pairs).
