Abstract
A vertical drive shaft lawn edger is disclosed having a curb support roller system. A support roller is mounted directly behind the blade of the lawn edger. A height adjustment mechanism controls the height of the front wheel and the support roller in unison. The support roller has a smaller outer diameter than the front and rear wheels. Therefore, when edging along side a curb the support roller contacts the curb thereby providing support when the front wheel is suspended above the ground.
