  • Patent number: 5150999
    Abstract: Apparatus for lifting round bales of hay including a pair of arms which project forwardly from the front end of a tractor. These arms support a pivotal structure which includes a spear for impaling a round bale of hay and thereafter tilting the bale up off the ground. Another embodiment includes a device similarly attached to the forward end of a tractor; however, the latter embodiment involves a spear which can be elevated with respect to the ground while remaining parallel to the ground. A third embodiment involves a bale lifting device which is similar to the second embodiment but which can be attached to a conventional 3-point hitch on a tractor or to the rear of a flatbed trailer. A still further embodiment includes a square frame supported from a tractor by means of a 3-point hitch connection. The square frame rotatably supports an elongated rectangular frame which has impaling spears at the opposite ends thereof.
