Abstract

A lawn mower includes: a cutting blade motor that drives a cutting blade; a mode selector that selects one of modes including a normal lawn mowing mode and a grass removal mode in which grass accumulated at the cutting blade is brushed away; and processing circuitry configured to control the cutting blade motor in the mode selected by the mode selector. In the normal 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 the rotational frequency or torque of the cutting blade motor changes more significantly than the rotational frequency or torque of the cutting blade motor in the normal lawn mowing mode, or the cutting blade motor rotates in a reverse rotation direction.
