ABSTRACT:
A hay roll bagging system for bagging a number of hay rolls as have been cut, harvested and dried in a hay field into a plastic sleeve that, is maintained in a stretched state during bagging and then tighten around each hay roll, which sleeve is tied at its ends forming a container. The system is preferably mounted onto a wheeled trailer to be moved into the hay field and includes a cradle structure to receive each hay roll, in turn, and includes a ram for urging a hay roll end off of the craddle and through a collapsing ring. The collapsing ring of the invention is mounted to the trailer across a craddle rear end and is formed to have, in an erected state, a greater diameter than that of a hay roll. The ring receives a folded plastic sleeve therearound when the ring is in a collapsed state. The collapsing ring includes an arcuate bottom section that is fixed to extend upwardly from the trailer frame, across the craddle, that hinge connects, across its ends, to respectively, ends of a pair of arcuate pivot sections, that, in turn, are hinge connected across their opposite upper ends to opposite ends of a folding section, completing the ring. A single double acting piston arrangement is mounted to urge the folding section radially into the collapsing ring and to pull it out therefrom, providing for a collapse of the collapsing ring to received the folded plastic sleeve positioned therearound and for pulling that folding section radially erecting the collapsing ring, and stretching the folded plastic sleeve thereon.
