Abstract: A unitary digging tooth is removably mounted to an excavating machine. The tooth has a cutting face formed at a working end which is opposed to a trailing end thereof. An upper end of the tooth is removably attached to the excavating machine. A plurality of discrete teeth are made integral with and extend forward of the cutting edge. The upper marginal end of the tooth is relatively flat, and the lower marginal end of the tooth is a segment of a cone, and therefore curves when viewed in lateral cross-section. The individual teeth are spaced apart, and arranged parallel to one another, and form part of a digging face at the forward end of the tooth. The tooth is oriented in a vertical plane.
