ABSTRACT:
A ground anchor includes a planar drive head with a shank extending therefrom. The shank includes a plurality of inline segments with each segment including a cylindrical shaft portion and a cone-shaped tapered portion. The tapered portion of each upstream segment is connected to a shaft portion of an adjacent downstream segment. This relationship presents a plurality of indentations along the length of the shaft. Upon penetration of the shank into the ground, the earth collapses into the indentations which resist withdrawal of the anchor from the ground due to forces acting on the structure secured to the anchor such as a tarpaulin or the like. The planar drive head lies adjacent the ground to preclude above ground interference.
