Abstract
A lawn mower includes a chassis, a cutting deck, a chore motor, and a blade. The chassis supports several wheels. The cutting deck is supported by the chassis and defines a cutting chamber. The chore motor is electrically coupled to the battery. The chore motor includes a housing containing a coil assembly, a rotor, and a drive shaft extending out of the housing. The chore motor is attached to the cutting deck so that at least a portion of the housing and the drive shaft are positioned within the cutting chamber. The blade is coupled to the drive shaft and is configured to rotate within the cutting chamber when the chore motor rotates the rotor and drive shaft.
