Abstract: The present invention is directed to a control circuit for automatically bringing a hydraulically operated work arm into a particular position without having to manually reverse the direction of the hydraulic operating system.

Abstract: A system for supplying an implement with hydraulic fluid includes a first hydraulic pump generating a first flow, a second hydraulic pump generating a second flow and a valve assembly adapted to be coupled to the implement and coupled to the first and second flows. The valve assembly couples the first flow to the implement. The valve assembly also selectively adds the second flow to the first flow to provide a low flow or a high flow. The valve assembly couples the first flow to the implement via a first coupling in response to a first signal and via a second coupling in response to a second signal. The system further includes a manually operable control coupled to the valve assembly and movable between the first position which the first signal is generated, a second position in which the second signal is generated and a third position in which a third signal is generated. The system also includes a foot pedal control coupled to the manually operable control and to the valve assembly.
