ABSTRACT:
A bucket system which includes a bucket having a bottom with a digging edge. An impact-type penetration member projects beyond the digging edge to penetrate the surface of a body being excavated. The free edge of the penetration member is continuous and is at least as long as the bucket is wide. Bearing surfaces and restraint surfaces enable the penetration member to be driven by an impact member with reduced wear, and with the ability to respond to irregularities in the surface being penetrated. Preferably the penetration member includes a pair of deflector wings spaced apart farther than the sides of the bucket.
