Abstract
A unique motor for powering a cutting unit in an electric mower is disclosed. The motor is mounted above the cutting unit. A second motor is provided to drive one or more accessories and is also mounted above the cutting unit. The motors are symmetrically placed toward opposite ends of the cutting unit. The second motor acts as a counterbalance to the first, so the cutting unit has similar weight on both of its ends. This eliminates the need for a torsion spring counterbalance system, allows increased mobility of the cutting unit, and facilitates servicing of the cutting unit.
