  • Patent number: 5664924
    Abstract: A new Round Bale Handling System for offering a simple inexpensive device for lifting and unrolling round bales. The inventive device includes a frame, a lifting shaft, two tow chains, and a roll shaft. In use, the farm tractor 4 is backed up and the lifting shaft 30 is forced longitudinally axially into a round bale 2. The farm tractor's hitch is then used to lift the round bale 2 and the round bale 2 can be hauled by the farm tractor 4 to any desired location. When the round bale 2 has been placed, the farm tractor 4 is then relocated around and backed up to the round bale 2 so that the farm tractor 4 is normal to a rolling axis of the round bale 2. The roll shaft 50 is then pushed through the round bale 2 along its rolling axis and the tow chain 40 is rotatably attached to the roll shaft 50 by use of the retaining pin 56 and the hair clip pin 58. The farm tractor 4 then pulls the roll shaft 50 and the round bale 2 rotates about the roll shaft 50 and unrolls as it does so.
