ABSTRACT:
A vertical drive shaft lawn edger has an arbor which allows the cutting blade to extend outwardly from the lawn edger, yet still be rigid and stable. The arbor is located at an angle .alpha. with respect to a longitudinal axis running perpendicular to the rear axle and lying within the same plane. The angle .alpha. is preferably 5.degree. or less. The arbor is mounted to a frame of the lawn edger by a bracket and screws. A pivoting assembly enables the arbor to pivot thereby increasing or decreasing the angle .alpha..
