Adjust Brakes

CAUTION
Before and after adjusting the brakes, always
check the brakes in a wide open area that is flat
and free of other persons and obstructions.
1. Check brake adjustment as follows:
A. Park machine on a level surface, lower cutting
units, stop engine, and remove key from the ignition
switch.
B. Rotate by- pass valve on the piston pump 90 de-
grees to allow front wheels to turn freely (Fig. 2).
CAUTION
Before jacking up the machine, review and follow
Jacking Instructions in Chapter 1 - Safety.
C. Chock rear wheel. Jack up both front wheels and
safely support the machine.
D. Apply the parking brake. The force to actuate the
brake lever should be from 30 to 40 lbs (133 to 178
N).
E. With the parking brake applied, use a torque
wrench on the wheel hub lock nut to identify the
break away torque at each front wheel. The mini-
mum break away torque with the parking applied
should be 300 ft- lb (407 N- m).
2. If adjustment is necessary, adjust brakes as follows:
A. Remove both front wheel assemblies from the
machine (see Front Brake and Wheel Removal in
this section).
B. Adjust brakes by turning clevis to increase or de-
crease shoe pressure on the brake drum (Fig. 3).
Make sure that brake shoes do not drag against
drums with the parking brake lever released.
