  • Patent number: 4248561
    Abstract: The device includes a bed which is pivotally attached to a transverse axle supported by a pair of wheels. The bed is pivotable on the axle for lowering either end to a position proximate the supporting, ground surface. The bed contains a pair of parallel beams, the free ends of which are attached to laterally diverging bale guides for surrounding a bale to be lifted onto the beams. The beams also contain downwardly converging bale contacting surfaces each of which includes a recessed conveyor chain having protruding spikes for engaging the bale. The beams are spaced so as to cradle the bale between them while the spikes slide the bale upwardly along the beams. A pivotal tongue is attached to the transverse axle for towing the device directly behind a tow vehicle or towing the device behind and laterally to one side of the tow vehicle.
