Lawn mower

A lawn mower comprising:

• at least one cutting blade motor that drives a cutting blade;
• a mode selector that selects one of modes including a lawn mowing mode and a grass removal mode in which grass accumulated at the cutting blade is brushed away;
• a driving wheel;
• a driving wheel motor that drives the driving wheel;
• and
• processing circuitry configured to control the cutting blade motor in the mode selected by the mode selector, wherein:
• in the lawn mowing mode, the cutting blade motor is controlled so as to rotate in a normal rotation direction at a predetermined rotational frequency or with a predetermined torque;
• in the grass removal mode, the cutting blade motor is controlled such that a rotational frequency or a torque of the cutting blade motor pulsates, or the cutting blade motor rotates in a reverse rotation direction;
• the at least one cutting blade motor comprises cutting blade motors that drive corresponding cutting blades;
• the processing circuitry controls any one of the cutting blade motors in the grass removal mode;
• and
• when the lawn mowing mode is switched to the grass removal mode, the processing circuitry maintains the grass removal mode and stops or decelerates the driving wheel motor.
