Discussion of Key Technologies for Applying Motorcycle on Light-duty Agriculture Power Machines

The designing requirements of light-duty agricultural machines for mountainous regions are characterized by simple power unit, modularization, multifunction, easy operation, and convenient to move in fields. As the main transport facilities in rural and mountain areas of China, the motorcycle which possesses lightweight, low cost, high quality, well maintenance conditions, is suitable to be modified to a light-duty agriculture machine. A three-wheel structure is constructed by replacing the original rear wheel of motorcycle with two impellers wheels for comfortable and stable control in field operation. In order to get differential, low speed, large working torque in field operation, a hydrostatic differential device which is composed of a constant flow pump and two variable displacement motors is designed. A general hanging mechanism is installed on the rear body of the modified motorcycle for connecting agricultural implements.
