ABSTRACT:
A tractor-mounted forklift comprising a first frame having its rearward end secured to the underside of the tractor and having its forward end secured to the forward end of the tractor about a longitudinally extending pivot axis. A second frame is pivotally secured, about a transverse axis, to the forward end of the first frame and has a pair of ground-engaging wheels mounted at the opposite sides thereof. A hydraulic cylinder is pivotally connected to and extends between the first and second frames to pivot the second frame upwardly and downwardly with respect to the first frame. A materials handling attachment, such as a bale grapple, is mounted on a vertically movable lift which is secured to the forward end of the second frame. When the hydraulic cylinder is extended the second frame is pivotally moved downwardly with respect to the first frame so that the weight of the product being handled is transmitted to the second frame and to the ground by means of the wheels at the outer ends thereof, rather than to the tractor.
