-17- "BALE UNROLLER" ABSTRACT OF THE DISCLOSURE Round hay bales usually weigh up to 2,000 lbs. and are difficult to unroll so that cattle can obtain ac- cess to them for feed. The present invention comprises a frame attachable to a three-point hitch of a tractor. One fixed arm extends perpendicularly from one side of the frame and a hinged arm extends from the other side and is movable in a vertical plane by means of a hydraulic piston and cylinder assembly. Each arm is provided with a bale engaging spike or prong and when it is desired to unroll a bale, the hinged arm is opened and the two prongs are engag- ed axially of the bale whereupon the hinged arm is closed. The three-point hitch mechanism allows the bale to be ele- vated clear of the ground so that it may be transported by the tractor to the desired location. The three-point hitch assembly is then placed in the float position with the peri- meter of the bale engaging the ground. As the tractor moves forwardly, the bale rotates on the prongs and unrolls. As the three-point hitch is in the float position, the unroller gradually tips rearwardly due to the weight of the bale, thus keeping the periphery of the bale, which is decreas- ing in diameter, always in contact with the ground.
