A portable apparatus for driving a post into the ground is provided in an embodiment. The apparatus has a base removably attachable to the post as well as a hammer module tethered to the base to permit vertically reciprocating motion of the module relative to the base and post. The apparatus may be motor driven with rotating, eccentrically mounted cams providing the mechanism for creating a hammering force through reciprocating motion. The hammer module has a face which imparts the hammering force to the top of the post. A method for using such an apparatus is provided in a further embodiment.
