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.

Hydraulic control circuit for implement

A snow blower implement for a power machine includes a power machine interface having a machine mount configured to engage the implement interface of the power machine. A tool of the implement is coupled to the power machine interface. The tool includes a frame forming an auger housing, and the auger housing includes apertures formed in the housing and arranged to proved an operator of the power machine with visibility, through the apertures, of an implement workspace within or in front of the auger housing while operating the power machine.

Snow blower implement

Power machine bucket implements include a rear wall structure, a bottom wall structure adjoining the rear wall structure at a bend region, and a two-piece brace. The two-piece brace includes a first piece attached to and extending along a portion of the bottom wall structure and a second piece, separate from the first piece, attached to the back side of the rear wall structure.
