Abstract
Abstract A post anchor (A) is disclosed for anchoring a post (18) and the like in ground soil which comprises an elongated shank (10) having a boring end (14) and a bracket end (16). An auger (B) is carried at least near the boring end of the shank for boring a hole in the soil. A bracket (C) is carried near the bracket end of the shank for attaching the post to the shank. A compactor plate (D) is carried by the shank near the bracket end for compacting the soil between the compactor plate and the auger. A drive coupling (F) attaches to the bracket for connecting to a power drive for rotating the coupling and elongated shank. The drive coupling has a first position for connecting to the bracket for screwing the anchor into the ground and a second position for connecting it to the bracket for screwing the anchor out of the ground.
