  • Patent number: 5154399
    Abstract: A tool for removing or raising landscape edging strips has a rigid main frame including two parallel and spaced apart bars, and an elongate upright lever. The lever is pivotally mounted to the main frame near its lower end, by a pivot pin extending through the bars and lever. A base pad is mounted to the main frame at an end remote from the pivot pin. Mounted to the main frame on the opposite side of the pivot pin, are a platform and a downwardly depending arm that supports a first clamp. A second clamp is mounted to the bottom of the lever, and moves arcuately as the lever pivots, to close both clamps about an enlarged upper border portion of the landscape edging material. Further pivoting of the lever, with the base pad against the ground, applied a vertical lifting force to the landscape edging strip, either to elevate and reposition the edging material, or to completely remove the edging material from the ground.
