Abstract
A digging tooth and holder therefor for use with an excavating machine including trenchers and backhoe buckets. The tooth holder is suitably attached to the excavating machine, and includes a tooth receiving pocket formed therein for removably receiving the shank of a digging tooth in an improved manner therein. The digging tooth shank rearwardly extends from the tooth and is made into a special configuration which enables power applied thereto from the excavating machine to be transferred into the working end of the tooth in a new and unusual manner. The working end of the tooth inculdes an elongated, concave upper surface, a cylindrical lower surface, and a plurality of longitudinal extending reinforcing ribs which are formed on the cylindrical lower surface, all of which cooperate together to impart great strength into the tooth and also enables the tooth to dig in hard formations in an improved manner.
