Abstract

See full text

Disclosed embodiments of power machines, implements and hydraulic systems utilize a hydraulic flow control circuit and method to implement multiple modes of operation while optimizing hydraulic fluid flow to either or both of primary and secondary function actuators. In a first mode the hydraulic flow control circuit is configured to receive pressurized hydraulic fluid flow from a first conduit and to provide the pressurized hydraulic fluid to the primary and secondary function actuators. In the first mode, the circuit is configured to direct return flow from the primary and secondary function actuators through the second conduit for return to the power machine. In a second mode, the circuit receives flow from the second conduit, provides the flow only to the secondary function actuator, and directs the return flow to the power machine through the first conduit.
