Implements for attaching to a hand-held, powered "Weed-Eater" type device to perform various work or chores (filament cutting, blade cutting, brushing, blowing, mixing, etc.). After disconnecting the device's original implement typically a spool of filament (6) with a bumper feed (7), an initial, cultivator/cutter implement (10), cylindrical in shape with a substantially solid, circular top (12) and a relatively thin, continuous wall of constant thickness, is attached by an appropriate threaded member (e.g. a nut or bolt, usually with one or more washers) to the bottom end of the powered device (FIGS. 1A-D) through a central opening (13). The cultivator's top includes a series of circumferentially spaced, "snap-in" openings (14; e.g. two or more) through and into which other implements (e.g. those of FIGS. 3-20) can be attached (FIGS. 2A & B) with the use of a like number of upwardly extending, "snap" legs (21a & b), the adapter then functioning as a "universal" adapter for changing in and out various work implements as desired by the user, with a quick and easy removal and addition of an implement with "snap-out"/"snap-in," twist actions. The cultivator/adaptor also includes a series of circumferentially spaced, inwardly offset protrusions (16) extending down from the circular side wall bottom (15), which protrusions dig into and cultivate the ground, removing undesirable vegetation when rotated by the powered device. Side hole sets (17) are provided for adding cutting filament sections (18) for supplemental or alternative filament cutting.
