ABSTRACT:
A round bale feeder for transporting and unwinding round bales of hay. The feeder includes wheeled frame carried on ground bearing wheels for towing behind vehicle, and tilting frame hinged to wheeled frame for tilting about hinge axis disposed normally to direction of travel. Front, mid and rear rollers journalled on tilting frame for rotation about axes parallel to hinge axis. Front and rear rollers are spaced apart sufficiently to support a complete round bale thereon, and mid-roller is sufficiently close to one of the remaining rollers to support bale when almost completely unwound. Tilting cylinder cooperates with tilting frame so that actuation of tilting cylinder rotates tilting frame to load bale thereon, and to support bale on rollers. Rollers are powered to rotate bale to unwind swath therefrom as feeder traverses distribution area. Rollers have resilient surfaces which deform under load to produce tooth-like projections to increase forces on bale and to reduce accumulation of unwanted matter thereon.
