<p>A digging tooth (10) including a body portion (12) and a plurality of hard wear resistant conical inserts (14). The body portion includes a generally planar distal portion (16), a medial portion (18), and a bifurcated proximal portion (20) having at least two prongs (22, 24) separated from each other to form a slot (28). The conical inserts are secured to and spaced along said distal portion and have a generally cylindrical body portion (38) and a top portion (40) which tapers to a point to form a tip (42), wherein the ratio of the diameter of the cylindrical body portion to the spacing distance between the tips of the conical inserts is between 0.50 and 0.80 and, preferably, 0.72.</p> |
