Zusammenfassung:A lawn mower includes a chassis supporting a wheel, a cutting deck supported by the chassis and defining a cutting chamber, a battery supported by the chassis, and a chore motor electrically coupled to the battery. The chore motor includes a housing with 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 in the cutting chamber. The lawn mower further includes a blade coupled to the drive shaft so that the blade rotates within the cutting chamber when the chore motor rotates the drive shaft, and a spring washer coupled between the drive shaft and the blade. Relative rotation between the blade and the drive shaft occurs in response to a torque on the blade exceeding a threshold value.
