Abstract
A lawn mower includes a blade configured to cut grass, a chassis, configured to accommodate the blade, and front and rear wheels connected to the chassis. A motor is configured to drive at least the rear wheel to rotate. A detection apparatus detects the rotational speed of the front wheel and a controller controls the motor. Accordingly, the speed of a front wheel is detected to control a moving speed of the lawn mower, thereby enhancing the performance of the lawn mower and improving the user's experience.
