Abstract

Abstract A machine adapted to be towed behind a tractor for loading, shredding, and feeding a cylindrical bale of hay of substantial size and weight. The machine includes a hopper within which a plurality of power driven shredders is disposed for shredding hay from a bale introduced into the hopper. A bale gripping and lifting apparatus is pivotally mounted for engaging a bale on the ground and raising the bale above the hopper. The gripping portion of the apparatus is released to permit the bale to move against the shredders by gravity for progressive shedding of the bale. An auger conveyor is disposed beneath the shredders for conveying the shredded hay out of the hopper. A discharge conveyor receives the hay from the auger and discharges it to the side of the machine for deposit in a windrow on the ground or into a feed bunk as the machine is moved by the tractor.
