<p>An electrically powered earth coring device may be used to removeweeds from lawns or flowers beds. The device comprisesa hollow shaft (3) having a handle (1) and a hollow cylindrical cutter (5), extensible from the lower end of the shaft to penetrate the ground around the root of a weed (34) and create a core of earth. When a preset depth has been reached, the cutter (5) is retracted in order to remove the core of earth and the weed from the ground. A plunger (16), mounted inside the shaft (3), pushes the core of earth out of the cutter as the latter is retracted. Opposing claws may be mounted pivotally at the lower end of the cutter (5) in order to grip the root of the weed. The coring device may also be used for planting bulbs.</p> |
