ABSTRACT:
An apparatus designed to facilitate the unrolling of baled hay has a main frame mounted onto a tractor or other vehicle. An upstanding arm attached to the frame carries a hydraulic cylinder and piston assembly, which assembly supports and selectively positions an axle and wheel. The axle is positioned so that the wheel contacts a tire of a vehicle. As the vehicle causes the tire to rotate, the wheel is also rotated but in the opposite direction from that of the tire. The wheel is driven by the vehicle against a rolled bale of hay. As the vehicle is driven, the wheel abuts the bale of hay and causes it to unroll.
