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.

A soil working assembly and a torque producing output shaft adapted for rotating said assembly by a power means, said assembly comprising; a guide rod demountably secured coaxially to the output shaft for rotation therewith about an axis substantially normal to the soil surface, said guide rod having an internally threaded hub means integral with the mounting end thereof, with the depending end being formed at a selected angle to define a soil boring tip; a soil engaging member formed of a flat length of metal to define a support base from which depends at least a pair of tines, each having a tip at the ends thereof, with the guide rod extending axially therebetween beyond the tine tips and rotatable about the same axis; wherein the flat tines are disposed with a sharpened leading edge and a trailing edge, the tips of the tines being formed at an angle to their direction of motion with the leading edges being longer than the trailing edges thereof; a reinforcing member secured to the pair of tines immediately below the support base to strengthen the assembly against torsional forces produced by contact of the tines with the soil; and the assembly further including, said support base having a square hole formed therein, a square shank formed along an end portion of the output shaft, a shoulder formed in the output shaft and terminating the square shank, threads formed along the end of the output shaft, wherein the square hole of the support base fits over the square shank, and the soil engaging member is demountably secured to the output shaft for positive rotation therewith by threading the hub means onto the threaded end of the output shaft to confine the soil engaging member therebetween.
