In the operation of a work machine attachment of the type utilizing fluid cylinders, it is desirable provide a way to conveniently operate each of the fluid cylinders while locating any hydraulic conduits required to operate the fluid cylinders away from the operator cab. The present invention provides for a hydraulic positioning system for use with a work machine attachment of the type having a frame, a tool, and a plurality of fluid cylinders coupling the tool with the frame. A fluid deflection device is coupled to at least one fluid cylinder and is in fluid communication with an auxiliary hydraulic circuit having a fluid source. A primary hydraulic circuit is in fluid communication with the fluid deflection device and operable to selectively deflect the fluid source of the auxiliary hydraulic circuit to at least one of the fluid cylinders.
