A weed extractor is designed with a shaft (100) having a handle end and a distal end. A foot piece (116) has a first end and a second end. The first end is slidely attached to the shaft proximal to the distal end. The foot piece extends laterally from the shaft. A bit assembly (118) has a plurality of pivotally mounted opposed spikes. The bit assembly has an open position and a closed position, and moves between the open position and the closed position in response to movement of the foot piece with respect to the shaft. At least two opposed spikes are spaced apart from a plane bisecting an angle between the at least two opposed spikes in the open position. A part of each of the at least two opposed spikes intersects the plane in the closed position.

[ What is claimed:] [1.] An extractor, comprising:a shaft having a handle end and a distal end;an elongated foot piece having a first end and a second end, the first end slidely attached to the shaft proximal to the distal end;a bit assembly attached to the distal end of the shaft, the bit assembly having a plurality of pivotally mounted opposed spikes, the bit assembly having an open position and a closed position, the bit assembly moving between the open position and the closed position in response to movement of the foot piece with respect to the shaft;a detent stop connected to one of the shaft and the foot piece; anda detent piece connected to the other of the shaft and the foot piece, the detent piece having a first position and a second position, the detent piece engaged with the detent stop in the first position, thereby holding the bit assembly in the closed position, the detent piece disengaged from the detent stop in the second position, thereby permitting movement of the bit assembly between the open position and the closed position.
