ABSTRACT:
The present disclosure relates to a cutting tooth for a trencher chain. The tooth includes a base portion aligned along a first plane. The base portion includes structure for allowing the cutting tooth to be connected to the trencher chain. The tooth also includes a distal portion that is generally obliquely aligned with respect to the first plane. A curved transition is located between the distal portion and the base portion. The curved transition curves away from the first plane and at least partially forms a cupped portion that extends from a leading end to a trailing end of the cutting tooth. The tooth also includes a hardened tip positioned at a region of the leading end that is located farthest from the first plane.
