Abstract
An edger having a main frame that can be advanced controllably relative to subjacent terrain, a cutting assembly on the main frame, and a drive for rotating the cutting assembly around a first axis. The cutting assembly has a plurality of cutting teeth that dig into underlying terrain as the cutting assembly is operated to thereby cooperatively produce a trench in the underlying terrain. The plurality of cutting teeth includes a first cutting tooth that has an elongate configuration with a leading end and a length extending along a first line. The first cutting tooth is oriented on the cutting assembly so that the length of the first cutting tooth traces a path with a circumference that has a radial extent with respect to the first axis that is substantially less than the length of the first cutting tooth. The length of the first cutting tooth is aligned generally in a circumferential direction.
