Brake Maintenance
Adjusting the Service
Brakes
Adjust the service brakes when there is more than
13 mm (1/2 inch) of free travel of the brake pedal, or
when the brakes do not work effectively. Free travel
is the distance the brake pedal moves before braking
resistance is felt.
1.
Park the machine on a level surface, lower the
cutting units, engage the parking brake, shut off
the engine, and remove the key.
2.
Disengage the locking latch from the brake
pedals so that both pedals work independently
of each other.
3.
To reduce free travel of the brake pedals, tighten
the brakes as follows:
A.
Loosen the front nut on the threaded end of
the brake cable

1. Brake cable
B.
Tighten the rear nut to move the cable
backward until the brake pedals have 0 to
13 mm (0 to 1/2 inch) of free travel.
Note:
Make sure that there is no brake
tension when you release the pedal.
C.
Tighten the front nuts after the brakes are
adjusted correctly.

Belt Maintenance
Servicing the Alternator
Belt
Service Interval: Every 100 hours
1.
Proper tension allows 10 mm (3/8 inch) of
deflection when you apply a force of 45 N (10 lb)
on the belt midway between the pulleys.
2.
If the deflection is not 10 mm (3/8 inch), loosen
the alternator mounting bolts

3.
Increase or decrease the tension of the
g009721
alternator belt and tighten the bolts.
4.
Check the deflection of the belt again to ensure
that the tension is correct.
