Abstract
Abstract A weed extractor device has an elongated member with a crank at its upper end portion and an extractor head at its lower end portion, the head having at least one blade, and preferably two, for insertion and rotation in soil. The blades have leading edge portions adapted for movement through soil and preferably define teeth adapted to facilitate movement and to retain weeds wrapped about the head. A weed ejector may be provided and has an ejector plate on a rod slidable relative to the elongated member for manual operation to eject weeds wound about the head.
