Patent ID: 7114272

Claim:
A digging tooth adapted to extend forward from a digging implement having a transversely extending edge, said digging tooth defining a longitudinal centerline and has a forward end portion, with a cutting edge extending thereacross and a rear end portion configured for attachment to the edge of said implement, said digging tooth further including upper and lower angularly diverging surfaces having opposed side surfaces therebetween, and with said digging tooth further including a wing projecting laterally outwardly from each side surface on said tooth, with each wing having upper and lower planar surfaces each extending in a direction generally paralleling the cutting edge extending across the forward end portion of the digging tooth and with the upper surface of each wing being disposed in other than a planar relationship relative to the upper surface of the digging tooth, and wherein each wing has a laterally widened rear portion, a laterally narrowed forward portion, and an outer edge extending therebetween for providing said tooth with a progressively widening ground fracturing zone whereby yielding significant wear protection for the edge of the implement.
