ABSTRACT:
A one-piece digging tooth having a socket opening to a rear end of the tooth for receiving and accommodating at least a lengthwise portion of a nose portion of an adapter extending forward from earth working equipment. The digging tooth has a top surface and a bottom surface which angularly diverge from each other between a forward end and the rear end of the tooth and two side surfaces. The tooth further includes a longitudinally elongated and centrally disposed tine with another longitudinally elongated tine outwardly cantilevered from and disposed to opposite lateral sides of and extending generally parallel to the central tine. To enhance their penetration capability, a width and thickness of all the tines constantly diminishes as the tines longitudinally extend toward the forward edge of the tooth. Opposed side surfaces on each tine are separated from each other by a longitudinally cleft whereby providing the digging tooth with at least two channels for directing materials, worked free by the tines, rearwardly toward and into the earth working equipment.
