  • Patent number: 5386681
    Abstract: A tool for use to remove weeds, especially dandelions, which comprises an open rectangular frame having an upper rod-like member defining a handle and a lower rod-like member of a length sufficient to receive the foot of an operator. This open rectangular frame gives room not only to the foot of the operator, but also to his or her knee, thereby making the tool much easier to use. The tool also comprises a tapered extraction tube externally secured to a lower lateral side of the frame. This particular positioning of the extraction tube is of particular importance, since, thanks to its eccentric position, a rotational force may be applied to it by both the hand and foot of the operator which holds the frame, respectively. Thanks to its structure, the taperated extraction tube is also self-cleaning, as it empties automatically when another plug of soil or earth containing a weed to be extracted is inserted therein.
