Abstract: A dozer blade attachment control system for a work machine comprises a dozer blade attachment coupled to the attachment coupler, a hydraulic circuit, and an electronic controller. The hydraulic circuit comprises a hydraulic pump, a diverter valve operable in a first position and second position, and a pressure compensated directional control valve. The electronic controller is communicatively coupled to the hydraulic circuit. The electronic circuit may modify the hydraulic circuit to one or more of a first configuration with the diverter valve in the first position for tilt, a second configuration with the diverter valve in the second position for angling, and a third configuration with the diverter valve in the second position and the pressure compensated directional control valve creating a shuttle flow path from a higher and a lower side of the hydraulic circuit for simultaneously tilting and angling.

Abstract: A work vehicle is disclosed. The work vehicle comprises an attachment comprising a cutting edge. The attachment is configured to move from an operating position to a dump position. An operator input device is configured to receive a grade command. A grade control system is communicatively coupled to an operator input device and configured to receive the grade command and define a cutting plane. A controller is configured to receive a boom position signal, an attachment position signal, and the grade command. The controller is configured to maintain the cutting edge on the cutting plane in both the operating position and the dump position.
