  • Patent number: 5316427
    Abstract: A device and method are provided for unrolling spirally wound bales of hay which are moved by hydraulic or electric operated bale spikes mounted on a vehicle such as a truck or tractor. The device is comprised of a tubular axle sleeve which fits over the bale impaling spike and is impaled along with the impaling spike into the hay bale when the bale is to be transported by the vehicle. After the bale is moved, the impaling spike is withdrawn leaving the axle sleeve impaled in the center of the bale. Bearings are employed at opposed ends of the axle which are free to rotate on the axle and are connected to lines on opposite sides of the rear of the vehicle. Movement of the truck causes the lines to rotate the axis of the bale from an axial position in alignment with the axis of the truck 90.degree. in order that the bale can be unwound in the manner of a spool to leave a mat-like web of hay upon the ground for feeding livestock.
