  • Publication number: 20060070751
    Abstract: A gardening tool extracts a weed along with a plug of soil. A plurality of blades are circumferentially spaced about an axis of a shaft and extend downwardly beyond the lower end of the shaft for insertion into soil about the roots. Each blade includes a trailing edge and a leading edge that leads the trailing edge during rotation in a selected rotational direction about the axis. An ejector body is positioned between the blades and is axially movable from an upper position to a lower position to eject soil from between the blades. An ejector control member at least substantially surrounding the shaft is axially movable by hand. A plurality of connecting members are circumferentially spaced about the shaft and connect the ejector control member to the ejector body, such that axial movement of the ejector control member causes axial movement of the ejector body.
