Abstract
A lawn edger attachment for power driven vehicles consisting of a rolling coulter blade carried for rotation on a horizontal axis transverse to the line of travel of the vehicle at one end of an arm pivoted at its opposite end to the vehicle on a parallel axis. Power means are provided for pivoting the arm. The blade is cup-shaped in order that earth pressure thereagainst will force it to follow the edge of a paved surface. The blade may be reversed so that the vehicle may operate either on the grass or on the pavement. The arm may be extended either forwardly or rearwardly from its pivot, for convenience in various situations. The arm is a horizontal parallelogram linkage, so that the blade can follow the pavement edge even if the vehicle is not steered precisely parallel to this edge.
