2. HYDRAULIC CIRCUIT

This model is provided with a full hydrostatic power
steering.
In the full hydrostatic power steering, the steering
controller is connected to the steering cylinder (1) with
only the hydraulic hoses. Accordingly, it does not have
mechanical transmitting parts such as steering gear,
pitman arm, drag link, etc. Therefore, it is simple in
construction. This steering system consists of the power
steering oil tank (3), hydraulic pump (4), steering
controller (2), steering cylinder, etc..
An oil tank dedicated for power steering is located
below the operator's seat. The oil in this tank is fed by the
hydraulic pump driven by engine to the steering
controller (3.5 to 8.4 L/min., 0.93 to 2.2 U.S.gals/min.,
0.77 to 1.8 Imp.gals/min.). With the steering wheel at
neutral, the oil returns through the controller to the oil
tank. Turn the steering wheel, and just a required
amount of oil is sent to the steering cylinder. The oil at
the side opposite to the cylinder flows back to the tank.
This power steering controller is of non-load reaction
type.
