ABSTRACT The present invention is a double-headed hammer slidingly encompassing a ground rod driving shaft having a single anvil affixed thereto which can be selectively engaged by either hammer. The driving shaft has a recess in each end to receive the ground- ing rod, depending upon whether the action is to initiate and con- tinue the insertion of grounding rod into the ground or to complete the insertion of the rod in accordance with the provisions of the Code. The present invention does not require the operator to take a position above the ground or to use any other instrument to make the complete and proper insertion of the grounding rod in- to the ground.
