ABSTRACT:
A non-rotatable excavating tooth has a forward ground engaging portion, a rearward shank portion which is cylindrical in cross-section, and a shield assembly. The shank has a keeper removably positioned thereon for releasably capturing the shank of the digging tooth within a tooth receiving pocket. The tooth receiving pocket preferably is welded to a bucket lip of a digging or trencher machine. The shield includes two opposed sidewalls which abuttingly engage the opposed sidewalls of the pocket, thereby rendering the tooth non-rotatable respective to the pocket. The non-rotatable digging tooth is interchangeable with and can be substituted for a rotatable type rock bit without any modification of the pocket.
