Abstract
An elongated horizontal wheeled frame is provided for receiving hay bales thereon and the frame is adapted to be moved longitudinally over the ground. One end of an elongated generally horizontal arm is pivotally supported from one side of the frame for horizontal swinging of the arm about an upstanding axis relative to the frame between a first position with the arm projecting outwardly from the corresponding side of the frame and a second position with the arm swung forwardly to a position closely paralleling the frame. The free end portion of the arm includes a hay bale engaging structure which projects outwardly from the side of the arm opposing the frame when the arm is in the second position thereof and the hay bale engaging structure is adapted to supportively engage a ground supported hay bale toward which the arm is laterally advanced when it is in the first position thereof as the frame is forwardly advanced over the ground. The hay bale engaging structure is supported from the arm for vertical shifting of at least the outer portion of the hay bale engaging structure relative to the arm and the frame, at a point spaced forwardly from the axis of oscillation of the arm a d…
