Brake Maintenance

Adjusting the Service Brakes

Adjust the service brakes when there is more than 1 inch
(25 mm) 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. Disengage the locking latch from the brake pedals so
that both pedals work independently of each other.
2. To reduce free travel of the brake pedals, tighten
the brakes:
A. Loosen the front nut on the threaded end of the
brake cable.
B. Tighten the rear nut to move the cable backward
until the brake pedals have 1/2 to 1 inch (13 to
25 mm) of free travel.
C. Tighten the front nuts after the brakes are
adjusted correctly.

Belt Maintenance

Servicing the Alternator Belt

Service Interval: After the first 10 hours
Every 100 hours
Check the condition and tension of the belts (Figure 63)
after every 100 operating hours.
1. Proper tension will allow 3/8 inch (10 mm)
deflection when a force of 10 lb is applied on the
belt midway between the pulleys.
2. If the deflection is not 3/8 inch (10 mm), loosen
the alternator mounting bolts (Figure 63). Increase
or decrease the alternator belt tension and tighten
the bolts. Check the deflection of the belt again to
ensure that the tension is correct.

Belts
Service Interval: After the first 10 hours
Every 50 hours
Check the condition and tension of the cutting unit drive
belts initially after 8 hours of operation and every 50
operating hours thereafter.
When properly tensioned, the extension spring (hook
to hook) measurement should be approximately 3.50
±.25 inch (inside). Once the correct spring tension is
attained, adjust the stop bolt (carriage bolt) until there is
approximately .125 +.060/-.000 inch clearance between
the head of the bolt and the idler arm (Figure 64).
