A tool for attachment to the end of the articulated arm of a backhoe or other power shovel is disclosed. The tool provides a forwardly directed blade, i.e. a blade directed away from the tractor unit of the power shovel. The blade is usable to excavate soil from under a buried pipeline and allows an operator to see the blade while in use. The blade of the invention is substantially planar in structure and is formed from a larger flat bottom plate welded to a smaller flat top plate. The tool additionally provides left and right ears, each ear having an upper and a lower pin hole for attachment to the end of the articulated arm. Each pin hole provides a reinforcing collar. Braces reinforce the connection between the blade and the ears.
