General. Hydrostatic service and parking brake systems share the same oil-bathed, multiple-disc arrangements
located within the final drive assemblies. Both brake systems, while controlled and operated separately, are spring-
applied, hydraulically released.
Service Brakes. A foot pedal is used for reducing engine speed, allowing machine to slow down. Depressing foot
pedal provides hydraulic braking and when pressed beyond detent spring, applies brakes to stop machine.
Parking Brakes. Parking brakes are applied under three conditions: by means of a parking brake switch controlled
by operator, when brake/deceleration pedal is fully depressed past the detent spring, and when engine is shut off.
Parking brakes are released when brake/deceleration pedal is released or if applied via parking brake switch,
pushing right side of parking brake switch.

operate the machine, including a NATO slave receptacle.
3. The major systems comprising the electrical system are:
