A riding lawn mower includes a running assembly, a power output assembly, a power supply device, a driver circuit, an operating device, and a control module. The running assembly includes running wheels and a first motor for driving the running wheels. The operating device is configured to set at least one of target torque or a target rotational speed of the first motor. The control module is configured to output a control signal to the driver circuit to make an input current or an input voltage of the first motor vary with a rotor position of the first motor and make an actual torque of the first motor reach or basically reach the target torque within a preset time.
