Abstract
A hand-held powered ground and soil cultivation device includes a handle, a first end of which includes a holding zone and/or a holding member for the user, and the opposite end of which includes a head to which a working tool is rotationally or pivotally attached. During operation of the device, the working tool performs a reciprocating oscillating movement along a portion of a rotation and about a predetermined central angular position under the effect of the movement transmitted by a drive unit including at least an electric actuator or a heat engine. The hand-held powered device is characterized in that the working tool is releasably attached to the head, the working tool being mounted on a drive shaft that performs a reciprocating oscillating rotational movement and forms a vertical or horizontal axis of oscillation for the tool. The central angular position of the working tool can be adjusted.
