ABSTRACT:
An apparatus for shredding debris from lawns and trees, such as twigs, leaves and like material has a housing in which a rotor is rotatably mounted about an upright axis. The plane of the rotor is thus generally horizontal and supported on a frame which permits movement across the ground. A vertical shaft engine is mounted on the upper side of the housing and supports the rotor within the housing cavity. The rotor has blades which generate an air flow as the rotor is rotating, to provide a vacuum in the center portions of the rotor. The vacuum draws material through a central opening in the bottom of the housing, and the blades impel the material outwardly toward pivotally mounted shredder blades at the outer periphery of the rotor. The rotor also mounts chipper blades in an upper surface thereof with an upwardly extending guide chute receiving limbs and guiding such limbs into the path of the chipper blades as the rotor is rotated, to chip branches, limbs and the like.
