Disclosed herein is a powered cultivating tool or the like which includes a prime mover disposed within a housing, an output shaft extending from said housing having a pinion fixed thereto, said pinion being placed in meshing engagement with a gear having a first roller thereon offset from the axis of rotation of the gear which engages a cam follower operatively connected to a cultivating implement such as a tine so that the implement displays an oscillatory pendulum-like motion about a vertical radial line extending from an axis rotation of the gear. It is contemplated that the gear has extending therefrom an axle whose opposed extremity from the gear is provided with a disc hub having a similar roller, cam follower and the like for accommodating either a terminal portion of the first cultivating implement, or a second cultivating implement so that the sychronization of the two cam followers can be beneficially altered as is required by gardening constraints and the like. |
