Abstract:
1. A hydraulic system for selectively providing pressurized hydraulic fluid flow to actuators on an implement configured to be hydraulically coupled to a power machine, the implement having a primary function actuator and at least one secondary function actuator, wherein the hydraulic system comprises: a hydraulic interface including first, second and third conduits to couple to the power machine, wherein each of the first and second conduits are configured to selectively receive pressurized hydraulic fluid from the power machine; a hydraulic flow control device positioned to selectively control pressurized hydraulic fluid flow from the primary function actuator and to at least one secondary function actuator; wherein in a first mode of operation the hydraulic flow control device is positioned to direct pressurized hydraulic fluid flow returned from the primary function actuator out of the implement through the second conduit; and wherein in a second mode of operation, the hydraulic flow control device is positioned to prevent pressurized hydraulic fluid flow returned from the primary function actuator out of the implement through the second conduit via the hydraulic flow control device.
