摘要： 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.

摘要： 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.

摘要： Outdoor power equipment including a frame, a battery, multiple wheels, a cutting deck, multiple chore motors, and multiple blades. The cutting deck is coupled to the frame and has a discharge opening. The electric chore motors are attached to the cutting deck and are selectively powered by the battery. Each of the blades is powered and rotated by one of the multiple electric chore motors. A first blade of the multiple blades is rotated in a first direction and a second blade of the multiple blades is rotated in a second direction opposite the first direction.
