ABSTRACT:
A portable, hand-held apparatus or implement employing various interchangeable soil working assemblies, wherein the latter rotate about an axis oriented substantially normal to the soil surface, i.e., the assembly rotates in a horizontal plane parallel to the soil surface. The soil working assemblies selectively include soil engaging tine, auger, drill, etc., members which depend via integral support bases from a central guide rod. The guide rod extends along the axis of rotation of the soil working assembly, wherein the tip thereof engages the soil prior to contact therewith by the rest of the assembly. The apparatus contemplates various power source configurations, mutually interchangeable with the various soil working assemblies, dependent upon the operation to be performed, the existing soil conditions, etc. Thus the apparatus may include manual, electrical, gas, etc., power sources and may employ cultivating, mulching, weeding, boring, etc., assemblies.
