Abstract
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.
