  • Patent number: 3946815
    Abstract: The present application discloses an invention whereby the common gardening tasks of sod cutting and lawn edging may be performed by a single tool. By providing a structural member of thin cross section and generally rectangular shape with a reinforcing member along its top edge, a suitable handle, and a pair of removable wheels, one on each side of said member, with one of said wheels being a larger lawn edging wheel and the other being a smaller sod cutting wheel, a dual-purpose lawn and garden tool is provided.With the small sod cutting wheel mounted in the appropriate position, the sharpened leading edge of the structural member will easily cut sod, and with the smaller wheel removed and the larger wheel mounted, the lawn edging operation can be performed. Removable spacer members of varying widths, and a deflector member, combine to determine the width of cut and direct the pieces of sod away from the trench produced.
