摘要： The plant puller is a hook attached at one end of a pole or handle. The hook is used to grip a plant to be pulled from the soil. While a standard circular hook may be used, a tapered hook which causes a compression of the plant as it is drawn into the tapered toe end of the hooks provides a firm grip for pulling the plant from the soil. The tapered hook may have a beveled inner surface with a stop in the toe tip to provide additional griping force when the plant is pulled. The weed puller may be used to pull plants at or above the soil surface or be forced into the soil and pulled to grip the plant roots below the surface.
