Abstract
An earth anchor apparatus adapted to be driven by a source of rotational driving force into unbroken soil includes a longitudinally extending hub having first and second axial ends. A recess is provided in one axial end of the hub by which the anchor may be driven, and a radially extending, load-bearing element is affixed to the hub between the axial ends. An earth engaging lead tip extends axially from the second end of the hub and includes a first cutting edge extending in a direction generally transverse to the longitudinal axis of the hub and arranged to cut into and break soil encountered thereby, a front surface extending between the hub and the first cutting edge, and a second cutting edge extending between the first cutting edge and the leading edge of the load bearing element. The second cutting edge is adapted to both cut soil and guide it from the first cutting edge toward the load-bearing element along the front surface so that as soil is cut it is moved away from the unbroken soil.
