Patent attributes
A scraper blade assembly for a vehicle such as a tractor or skid-steer vehicle has a frame having a socket with a pivotable ball for connection to the vehicle. The pivotable ball permits pivoting movement of the frame about a longitudinal axis, a transverse axis and a vertical axis of the vehicle. Tilt of a scraper blade mounted on the frame is controlled by left and right hydraulic cylinders and angle of the scraper blade is controlled by a third hydraulic cylinder. A control system has a single joystick which is capable actuating the left and right hydraulic cylinders independently or simultaneously. The combination of the pivotable ball mount to permit three degrees of freedom of movement of the frame and the ability of a single joystick to independently or simultaneously control the left and right hydraulic cylinders results in smooth and accurate blade placement for finer control over earth moving operations.
