ABSTRACT:
A ground anchor has an auger fluke defined by a lower leading and upper trailing beveled cutting edges, the shape of the edges being at a non-radial or oblique angle, the disc being vertically separated in the shape of a helix and attached to an axial anchor rod. The rod is set in the ground with a socket tool that is coaxially positioned over the rod. The tool includes a helical slot engagable with the helix of the anchor fluke to rotate the anchor into the ground, to pull test the anchor, and in one embodiment cpable to reverse rotate the socket tool for its removal.
