ABSTRACT:
An apparatus (10) for rotary extraction of weeds and other vegetation by hand or by using a power driver. The apparatus includes a hollow guide tube (20) in which a shaft (16) is slidably disposed. An extraction head having a plurality of pointed rods (12) or prongs (62) is coupled to shaft (16), and can be extended or retracted by movement of shaft (16) within the guide tube (20). The rods (12) or prongs (62) are extended and inserted into the soil over the vegetation to be removed. Rotation of the apparatus winds the vegetation and its root around the rods (12) or prongs (62) and removes it from the soil. The vegetation is then ejected from the apparatus by retracting the rods (12) or prongs (62) and, if necessary, sliding the vegetation off of the tapered sleeve (30).
