ABSTRACT:
An unrolling device for cylindrical hay bales spikes the bale on its axis and pulls it along the ground to unroll it, when the device is pulled by a pickup truck, tractor, or the like. It comprises a transverse crossbar, two arms hinged at their ends to respective ends of the crossbar, and spikes insertable through the arm ends. The arms may swing out from the bar to a right angle; when both are swung out they lie parallel to one another. The spikes fit through the arm ends to protrude inwardly in the same plane as the plane formed by the crossbar and arms. Thus when set up for use the device has the general shape of a serif capital letter C. In use, the arms are set out on either side of a bale and the spikes are inserted through the arm ends to penetrate the hay bale on its axes. The device is pulled by chains on the crossbar to unroll the bale. When not in use, the device folds into a compact linear shape; the spikes are removed and the arms are folded down. The spikes are stored, lying alongside the arms, in special holders so as to be out of the way.
