Dozer blade attachment control system and apparatus for a compact track loader

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.
