摘要:
A weed removal device having a handle and a frame through which a rod extends. The rod has a mechanical lock near one end that connects the rod mechanically to the frame, and a base portion near the opposite end. The base portion includes pins that extend into soil around the weed to grasp the weed, and a foot pedal on which the user rests his weight to drive portions of the device into the soil. A spring is compressed when the pins are driven into the soil and grasp the weed, and upon removal of the weed and a plug of soil the mechanical lock can release the spring to expand and thereby eject the weed and soil with force sufficient to propel the weed many feed into a receptacle.
