ABSTRACT:
A self-loading machine capable of transporting several round bales at a time has an overhead frame from which a pair of transversely spaced clamping jaws are suspended. The two jaws are elongated fore-and-aft and outwardly bowed so as to present a generally cylindrical container that is open at its front and rear ends. The machine is towed behind a tractor or other vehicle but can be hydraulically shifted to an offset position relative to the line of draft of the vehicle during pickup and discharge operations. When a bale is to be picked up, the machine is advanced with the jaws spread wide apart until the machine is disposed over the bale straddling the latter. By hydraulically lowering the machine into a pickup position, the jaws are then disposed to be closed together, causing long beams at the bottom of the jaws to be forced transversely under the bale and within the grip of the container. The machine is then elevated to raise the bale off the ground for transport to the next bale, whereupon the sequence is repeated until the container is full of a line of bales to be transported over-the-road or to another location.
