Abstract
An attachment apparatus which can be detachably mounted to a self-propelled vehicle, such as a skid-steer front end loader. The apparatus includes a frame which can be attached to the lift arms of the front end loader, and an axially rotatable work implement. The work implement may be positioned in at least two dimensions with respect to the frame by hydraulic cylinders. Secondary hydraulic lines which extend from each of the hydraulic cylinders, and a primary hydraulic line are hydraulically joined by a manifold. Electrically actuated valves connected to the manifold selectively provide communication between the primary hydraulic line and one of the secondary hydraulic lines to thereby control movement of the apparatus in each of the available dimensions. The control system requires that only one set of hydraulic cables be connected to the hydraulic pressure source of the vehicle, which simplifies attachment and removal of the apparatus, and provides safer operation, and reduced manufacturing costs.
