  • Patent number: 4148174
    Abstract: A flail type shredder for farm crops employing an elongated frame which is adapted to be mounted at the front end thereof on the three point hitch of a conventional farm tractor and which travels along the terrain supported by a pair of wheels mounted at the rear end of the frame which are adjustable with respect to the terrain to adjust the distance between the terrain and the frame. The chopper has a central elongated flail type crop severing unit mounted on and below the frame at the rear thereof and two elongated wing flail type crop severing units extending outwardly from opposite sides of the frame. The two wing units have housings open at the bottom and provided with a top, and each of these units is mounted on one of the side rails of the frame by a hinge located at the top of the unit, and each of the wing units is provided with a rotatable wheel adjustably mounted at the rear thereof to determine the distance between the terrain and each of the wing units separately.
