ABSTRACT:
A method and means for power mounting and dismounting a materials handling apparatus on a tractor. The apparatus comprises a first U-shaped frame which is adapted to be connected adjacent the rearward end thereof to the tractor rearwardly of the forward end thereof. The forward end of the U-shaped frame is adapted to be secured to the tractor adjacent the forward end thereof. A second U-shaped frame is pivotally secured adjacent its rearward end to the first frame and has a third frame pivotally secured to the forward end thereof. In one embodiment, a dozer blade is pivotally secured about a horizontal axis to the third frame. Power cylinders are provided for: (1) raising and lowering the dozer blade; (2) angling the dozer blade in two directions; and (3) raising one end of the dozer blade with respect to the other end. The method of mounting the apparatus on the tractor comprises the steps of: (1) driving the tractor adjacent the first frame so that the forward end of the tractor is disposed forwardly of the rearward end of the first frame; (2) actuating a power cylinder to pivotally move the forward end of the first frame upwardly relative to the second frame and to the tractor; (3) driving the tractor forwardly to effect a connection between the forward end of the tractor and the forward end of the first frame; and (4) actuating the power cylinder to raise the rearward end of the first frame for connection to the tractor.
