Abstract
A cutter tooth assembly for impingement of a material (e.g., a stump, wood, brush or earth strata). The assembly attaches to a driven member (e.g., a rotatable wheel). The assembly includes a cutter tooth which has an elongate body with a leading end and a trailing end, as well as a hard insert at the leading end of the tooth. The assembly also includes a pocket which has a base portion and a holder portion. The pocket attaches to the wheel at the base portion thereof. The cutter tooth is retained to the pocket at the holder portion thereof. The base portion of the pocket has a leading surface and a trailing surface. The cutter tooth is retained by the holder portion of the pocket so that the hard insert extends circumferentially past the leading surface of the base portion of the pocket.
