ABSTRACT:
An apparatus for controllably actuating at least two hydraulic actuator is provided. The apparatus controllably provides pressurized hydraulic fluid to the hydraulic actuators through closed center spool valves. The apparatus receives operating signals and a pump pressure signal and responsively controls the output of a variable flow pump. In a first mode, the output flow of the pump is a function of the operating signals and the pump pressure signal. In a second mode, the output flow of the pump is a function of the operating signals alone.
