Abstract (en)
[origin: WO2020033278A1] A method of stabilizing a small to mid-sized skid steer vehicles (12) used to grade earth using a dozer blade (46) in conjunction with GPS (42) automatic grade control equipment. The main arm (48) of the skid steer is retained at a specific height and the hydraulic (32) controlling the main arm is limited. The height of the dozer blade is raised and lowered by affecting the pitch axis of movement of the blade (46) and not by raising and lowering the main arm (48). The device is most suited to skid steer vehicles capable of using a variety of interchangeable front end accessories in addition to a dozer blade.
