ABSTRACT:
An apparatus for shredding/reducing the size of material yard waste and having: a housing defining an intake opening through which yard waste is to be drawn and an outlet opening through which yard waste drawn through the intake opening can be expelled; an impeller having a rotational axis and at least one vane for intercepting yard waste at the intake opening and propelling the yard waste intercepted by the impeller vane centrifugally to be expelled at the outlet opening; and a cutting structure/cutting attachment for reducing the size of yard waste drawn into the intake opening and advancing towards the impeller. The cutting structures includes at least one elongate blade having its length projecting substantially parallel to the rotational axis of the impeller. In one form of the invention, the blade rotates with the impeller.
