Abstract:
The subject matter of this specification can be embodied in, among other things, a system for securing a solar tracking device support member to a ground surface. A receiving member is adapted to receive the solar tracking device support member, and an anchor member including an elongate anchor shaft having a longitudinal axis, at least one ground pull-out restraining member disposed on a lower portion of the anchor shaft, and an expanded portion of the anchor shaft disposed longitudinally on an upper portion of the anchor shaft and adapted to support the receiving member. An uppermost portion of the upper portion of the anchor shaft is adapted to pass through an opening in the solar tracking device support. A biasing member is disposed about the uppermost portion of the anchor shaft, and a fastener is removably received on a distal end of the upper portion of the anchor shaft.
