  • Patent number: 4585072
    Abstract: An improved tool for removing weeds and for planting plugs of grass is provided with an elongated, upright sleeve having a hollow chamber at the lower extremity thereof. A plunger is operated to pass through the chamber by means of an elongated handle extending upwardly through the sleeve. The plunger is positioned over weeds or other undesirable vegetation and the walls of the chamber are pushed into the soil to surround the root system of the weeds and to define a plug of soil. The tool is then lifted from the soil, carrying with it the weed with the plug of soil containing the root system of the weed intact. The handle is operated to push the plunger through the hollow chamber to eject the plug of soil and the weeds carried therewith.
