1. HYDRAULIC CIRCUIT

[1] G23 MECHANICAL PTO CLUTCH MODEL

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 with only the
hydraulic piping. 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 oil strainer (2), the hydraulic pump
(3), the flow priority valve (7), the steering controller (11), the steering cylinder (12), etc..
The flow priority valve (7) located in the hydraulic control valve assembly (6) divides the oil into two directions.
One is the control flow to power steering (constantly 9.5 L/min., 2.5 U.S.gals/min., 2.1 Imp.gals/min.), and the other
is excessive flow to control valve of implement lift control.
By operating the power steering body, the required amount of oil is fed to the steering cylinder (12).
