ABSTRACT:
This invention is for a lawn edger. The edger has a strong unitary base mounted on a middle row of wheels and may be tilted backwards onto a rear roller. A motor is mounted on top of the base and a handle connects to the rear of the base. A cutter extends forward of the base and is held into position by a pair of forwardly extending rods. The cutter, which turns in a direction to throw any debris forward of the edger, is driven by a belt from the motor. A spring operating against one of the rods keeps a constant tension on the drive belt. A shield surrounds the cutter and has a guide with a lower rear position extending below the cutting blade. The edger may be run on a flat solid surface without the blade striking the surface. The edger is balanced with the middle row of wheels being the approximate center of gravity. The edger can tilt forward to the cutting position or rearward against the rear roller.
