ABSTRACT:
An ground rod driver including a tubular ground rod receiver engaging a prime mover at one end and having a ratcheting ground rod driving member and a clamping setscrew disposed at an opposite end wherein a ground rod may be inserted, clamped at an initial position and subsequently be driven by releasing clamp forces and operating the prime mover in a repetitive series of downward thrusting moves whereby the ground rod is installed. The clamping setscrew of the ground rod driver may be additionally employed to remove embedded ground rods by clamping an exposed end of an embedded ground rod to the ground rod receiver wherein the prime mover extracts the ground rod from the earth by repetitively performing an upward motion followed by clamp release, and a downward motion followed by reclamping until the ground rod is freed from the earth.
