Summary:An auger-like apparatus for boring planting holes includes an elongate shaft carrying a spiral blade or screw flight at its lower end. Means are provided at the outer end of the cutting edge to protect a sprinkler conduit or hose which may be contacted by the apparatus. In one embodiment, the outer end of the cutting edge is rounded and tapered into the peripheral edge of the screw flight. In a second embodiment, a guard extends between the outer edge of the cutting edge and a subsequent spiral of the screw flight. The shank may be graduated and support a slidable snap ring. A graduated tape mechanism is also provided to gauge the spacing of the plant bores.
