Abstract

A socket drive adapter for retrofitting to a solid hub earth anchor to convert the solid hub earth anchor into a socket drive earth anchor. The socket drive adapter is formed from a trapezoidally shaped steel plate by a series of 90.degree. bends. The bends create square, bore-defining adapter that can be welded to the top surface of the helical blade around the solid hub. A drive wrench fits in the socket drive adapter and engages both the socket drive adapter and the solid hub to enhance the torque strength of the anchor while retaining the better ground penetrating aspects of the solid hub design.
