Introduction
Power Steering
The Groundsmaster® 300 Series traction units are
equipped with power steering. The power steeringvalve
is enclosed in the steering tower at the front of the
traction unit. As the steering wheel is turned, the steer•
ing valve meters hydraulic fluid to the double-acting
steering cylinder on the rear axle and turns the wheels.
Hydraulic fluid flow for power steering is supplied by the
charge pump on the hydrostatic transmission. The im-
plement/steering hydraulic circuit is designed so priority
flow is provided for steering.
The Model HGF Hydraguide
TM
steering valve (Fig. 1) is
manufactured by TRW, Ross Gear Division.
NOTE: Because the steering cylinder has different dis•
placements when extended and retracted, the steering
wheel will not return to its original position after making
a turn.
NOTE: The steering system will operate with the engine
off if necessary (with increased effort).

Brakes
The Groundsmaster® 300 Series traction units are
equipped with 7 inch diameter x 1-3/4 inch wide
mechanical drum brakes on the front wheels.
Two pedals are used to control the brakes. When used
separately, the pedals can control each wheel brake to
assist steering or traction on side hills. The two pedals
may be locked together with the brake lock arm. When
the lock arm is engaged both wheels will brake equally
and act as a service brake or parking brake.
The brake pedals operate the brakes through a cable
system to a strut and lever on the brake shoes.
