The invention relates to a lawn mower, including: a housing; a walking mechanism, supporting the housing and driving the housing to walk, and including a drive wheel; a motor, used to drive the drive wheel to rotate; and a control apparatus, preset with a first torque threshold and a second torque threshold, where as the motor is switched from a stopped state to a running state, the control apparatus controls a difference between a maximum actual output torque of the motor and the first torque threshold to be within a predetermined range, when the motor is in the running state, the control apparatus controls an actual output torque of the at least one motor to at most increase to the second torque threshold, the first torque threshold is less than or equal to a maximum output torque of the motor, and the second torque threshold is less than the first torque threshold. In the foregoing the lawn mower, an actual torque acting on the drive wheel from the motor increases but does not exceed the second torque threshold, so that the drive wheel is prevented from overcoming the resistance to rotate, the drive wheel is prevented from rotating during a collision, and grass bruising is avoided.
