ABSTRACT:
A concrete breaking apparatus includes a non-circular multi-lobed impact roller connected via an axle to a wheeled frame such that the roller rolls upon the ground as the frame is towed by a tractor. Each lobe of the roller includes a ridge extending across the width of the roller and projecting outwardly from the impact surface of each lobe along a line parallel to the axle and generally centrally located within the dynamic impact region of the impact surface. The ridge may take various configurations, including a triangular cross-section, a semi-circular cross-section, and a plurality of spaced apart projections.
