Abstract
An electric lawn mower including an A.C. motor and a D.C. motor connected through a gearing and clutch arrangement for operation of either motor separately or concurrently. The gearing arrangement includes a mower blade drive gear acted upon by either of the respective driven gears associated with the A.C. and D.C. motors. The mower may be operated by either the A.C. motor or the D.C. motor separately, or by both motors combined to provide increased power to the cutting blade for mowing of dense areas of vegetation.
