ABSTRACT:
A lawn weeder in which the weed lifting prong is thrust downwardly by the foot at right angles from one end of the ground engaging the bottom lifting lever and thrust into the ground beside the weed by foot pressure upon the top of the prong end of the lifting arm and with a fulcrum structure over which the lifting lever is pivoted to effect lifting action of the prong and a curved handle extending upwardly from the rear end of the lifting lever to the waist of the user and a strut depending from the upper end of the handle to the bottom lifting lever to provide a complete quadrant-shaped operating handle. As the curved handle is grasped by the user at the waist height and passed across the front of the body, the weed will be easily lifted without effort and with the user not having to bend his back at any time. A ground-engaging fulcrum means is provided at the prong end of the lifting lever, which by foot pressure applied thereto, the prong is thrust into the ground beside the weed root. A ground-engaging foot plate carrying the fulcrum is hinged to the prong end of the lifting lever according to other forms of the invention to limit in movement whereby the foot can be easily kept upon the weeder during the lifting action and the weeder fulcrum provided upon the foot plate itself. If according to further forms, a curved handle and strut parts are so provided that the weeder can be collapsed for shipment and storage purposes. The weeder is shown made out of either tubing or a rod bent to the desired shape. The weeder can be made from a single rod length, the prong end swaged from the rod and a fulcrum made laterally coiling the rod adjacent to the prong and provided with further laterally extended fulcrum positions to provide for adequate ground contact.
