This paper aims at developing a new type of electrical brush cutter. The mechanical power of the conventional intern al combustion engine-type brush cutter is replaced by a DC brush motor. Moreover, a rechargeable battery is supplied with the necessary electrical energy when the electrical brush cutter normally works. A lot of advantages are then obtained such as low vibration and acoustic noise, free of air pollution, wider operating range and cheaper using cost and soon. The system controller is composed of a buck converter and a very friendly operating interface. For convenience, an electrical brush cutter with experiment al scale has been established in the laboratory. Finally, in order to verify the feasibility and function of the electrical brush cutter, lots of experiments were done through the established prototype. According to the experimental results, the anticipated feasibility and operating function of the proposed electrical brush cutter were confirmed.
