    Abstract: Gardening tool. A blade adapted to work the ground constitutes one side of a frame which is pivotably mounted on the housing of the tool about a shaft forming the opposite side of the frame. Drive elements within the housing are connected to a third side of the frame through transmission elements within the housing so as to impart to the blade a continuous pivotal vibratory movement. A detachable handle connected to the housing enables the latter to be handled. A cooling fan in the housing discharges air through orifices in the upper end of the handle.
