An apparatus includes a support attachment to couple a ground rod grabber to a top support; an upper line coupled to the support attachment; a hoist unit coupled to the upper line; a rod attachment to couple the ground rod grabber to a ground rod; and a lower line coupled to the rod attachment and threaded through the hoist unit. A method includes coupling a ground rod grabber to a ground rod; coupling the grabber to a top support while retaining at least two dimensions of freedom; and operating the hoist unit to exert pulling force on the lower line. A device includes a tube having a length-wise window; a threaded shaft disposed within the tube; a nut threaded on the threaded shaft within the tube; and a lifting lug coupled to the nut, extending through the window, and having a hole sized to fit a ground rod.
