ABSTRACT:
A forklift assembly for use with tractors having a conventional three point hitch includes a frame mounted to the tractor via the three point hitch. Raising and lowering the three point hitch raises and lowers the frame. A tine assembly slides along the lateral sides of the frame. A roller is rotationally mounted between the lateral sides near their upper ends. One end of a first cable is attached to the roller and the cable is wrapped around it in a first direction and the other end is attached to a stationary point on the tractor at a point below the roller. Second cables are each attached to the roller at one end and wrapped in a second direction around the roller and the opposite ends are attached to the tine assembly. Movement of the frame upwardly unwinds the first cable from the roller and winds the second cables onto the roller to raise the tine assembly along the frame. The height the tines are raised is equal to the height travelled by the frame plus the additional height the tine assembly moves relative to the frame.
