An earth anchor of the pivoting type having an essentially cylindrical
body, a blind bore extending therein to from a trailing axial end of the
cylindrical body and a leading edge projecting from a leading end of the
body, the leading edge chisel shaped for ease of penetration into the
ground, guiding surfaces extending substantially normal to the leading
edge and forward of the main body portion, the guiding surfaces having a
plurality of leading chisel edges stepped back from the leading edge and
from one another as the guiding surface leading edges are spaced further
away from a center of the leading edge, the guiding surfaces terminating
in final leading edge spaced axially from the leading edge and laterally
from each of the stepped leading edges and having at least a portion
which extend radially beyond the main body, guide ridges extending from
the final leading edges to the trailing axial end projecting radially
from the body substantially no further than the maximum width of the
guiding surface leading edges.
