A deadman ground-anchor comprises a heavy steel rod with several inches of machine threading at a back end, and an arrowhead with a pair of wedge-shaped wings at a front end. The wedge-shaped wings are welded to the steel rod. A pivotable fluke is hinged to the shaft with a lateral pin. The whole unit is driven into the soil, e.g., with a jack-hammer, until the threads at the back end are almost completely buried. A stabilizer vane and interlocking cap are then placed over the end flat on the ground. Nuts are put over the threaded end and tightened so that the whole unit is drawn back out a few inches. The fluke folds out perpendicular to the shaft and locks compacted soil between it and the cap. The stabilizing vane braces the top end of the anchor against lateral forces.
