Abstract
A digging tooth and bucket combination. The bucket has a V-shaped leading edge. Digging teeth are arranged vertically spaced from one another on the leading edge to cause the bottom of the excavation to be V shaped, with each side of the V being formed by a plurality of ledges. This causes the bottom of the excavation to have a stair-step configuration. Each digging tooth has a cutting edge arranged thereon to cut away material from a vertical side and a bottom of the ledge as the teeth penetrate the formation. The digging teeth are removably mounted to a shank, while the shank is rigidly attached to the V-shaped bucket lip. Forces imposed on the cutting edge of the teeth are transferred into the shank and then into the bucket lip in an improved manner.
