  • Publication number: 20150313075
    Abstract: A high performance tool for weed removal and transplanting small plants comprises a blade, foot step and elongated handle. The blade is attached to one handle end and the foot step is attached to the blade at the handle end. The blade tip is driven into the earth near a plant root or transplant location with operator foot pressure on the foot step. The operator then pushes downward on the opposite handle end and the tool operates as a lever with fulcrum at blade or foot step contact with the earth surface, causing the blade tip to lift upward and remove a plant or soil portion. A narrow flat blade with sharpened tip presents a small profile for easy earth penetration. A long handle allows the operator to work from a beneficial standing position, and leverage produced by handle to blade relative length amplifies blade tip lifting force.

  • Patent number: 9095087
    Abstract: A high performance weed pulling tool for removing the entire weed including the root comprises a rigid frame with a foot, two opposing jaws, a pivoting lever arm and an elongated handle. One jaw is attached to the frame in fixed position and the other jaw is attached to the lever arm. The handle operates the lever arm to close the jaws together and grip the weed stem. The greater handle length relative to the lever arm length below the frame pivot point provides a large gain in gripping and lifting forces. The rear jaw also pivots on the lever arm to conform the jaw surfaces to the taper of the weed stem for maximum surface contact while textured jaw surfaces maximize grip stability. The jaws self-retract when the handle is released allowing tool operation to be repeated rapidly for long periods of time with low fatigue for the operator.
