Abstract
A machine for sheathing bales of material such as hay, straw and the like. The machine has radially adjustable posts mounted on a polygon frame to stretch a resilient sheath for the free insertion of the bales. The polygon frame is configured with vertical sides that closely conform to the width dimension of the largest sheath in its stretched condition. The machine width is dictated by the frame width, i.e., the distance between the vertical sides and accordingly the machine has a width only as needed to accommodate the designated bale size, the restricted width being desirable for shipping and towing. Tandem wheels are provided on each side of the machine with the wheels strategically mounted in relation to the polygon frame to resist the tilting forces on the machine resulting from the weight of the bales.
