1. A concrete breaking apparatus comprising:
- a non-circular multi-lobed impact roller connected via an axle to a frame so as to follow the frame when the frame is propelled;
each lobe of the roller including an impact surface with a dynamic impact region which intermittently contacts the ground as the roller rotates on the frame; and
a ridge projecting outwardly from the impact surface of each lobe and oriented along a line parallel to the axle and centrally within the dynamic impact region.

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.

8. A method for breaking concrete, comprising:
-
affixing a projecting ridge to each impact surface of each lobe of a non-circular multi-lobed impact roller; said impact roller of the type rotatably mounted on an axle connected to a frame; and moving the frame over a predetermined area of concrete such that each ridge impacts upon the concrete as the roller rotates on its axle.
