ABSTRACT:
A lawn edger attachment for tractors consisting of a base member adapted to be mounted at the side of a tractor, a boom universally pivoted to the base and angling laterally outwardly from the base, and a generally vertical rolling circular blade mounted beneath the outer end of the boom for rotation both on its own axis and about a generally vertical axis. A single manual operating handle operates to pivot the boom horizontally to position the blade directly above a division line between the grass of a lawn and an adjacent paved area, as the tractor is driven in a direction parallel to the division line, and to pivot the boom vertically, as may be necessary to rest the blade on the ground surface at the division line, and a foot pedal then supplies a mechanically multiplied force to press the blade downwardly to penetrate the ground.
