ABSTRACT:
A post and ground support is illustrated utilizing a helical member forming an auger for digging the ground support into the earth, and easily removing the ground support from the ground and reusing said support in another location. The ground support includes a ground engaging stabilizing member affording resistance to a force having a component at right angles to the post, and a breakaway connection is provided between the ground support member and the post, together with a connection for retaining the post in a position near the ground after separation therefrom. The breakaway connection positions the post upon the ground support above the ground and separates in response to a force coming from any direction about the post. A shear pin having longitudinally flat surfaces extending circumferentially thereabout prevents turning of the post with respect to the ground support and a groove extending about said flat surfaces assure uniformity of shearing from any direction in which the force is applied.
