STEERING AND BRAKE SYSTEM

NOTE

Refer to WP 0144 00 for more detailed steering and brake system theory of operation information.

Control Valve. The valve is connected mechanically to the steering control levers. The valve directs the flow of pressur-

ized oil in response to the movement of the control levers.

Steering Clutch. One for each track, it controls the steering of the tractor. Hydraulically operated, it is controlled by the

steering lever in the operator station. When turning left, the left clutch is released. This causes the left track to stop mov-

ing and act as a pivot for the tractor to turn on. The reverse happens when turning right.

Brakes. The tractor has two band-type brakes (one on each steering clutch drum) which are used to stop the movement of

the tractor and to assist with the steering of the tractor. When the steering levers are pulled completely out, or the brake

pedals are depressed, the bands tighten around the steering clutch drum.
