Hydrostatic Power Steering System

A. Neutral Oil Flow When Tractor is Moving Straight :
This is the neutral position of the steering unit. In this position the oil flows from the
hydraulic pump to the steering unit, and because of the oil spool and sleeve hole being in
straight position the oil returns to the steering pump. In this system two shock valves and
two suction valves are fitted on the right and left sides of the steering unit. Shock valves
are used between the steering rim cylinder and steering ring control unit to protect this
system, whereas the suction valves are used to compensate any shortage of oil in the
system.
