Abstract: In order to accelerate the popularization and application of special harvesters for ratooning rice and increase the yield of ratooning rice, a comprehensive test was carried out on four special harvesters for ratooning rice organized by China Agricultural Mechanization Center, Ministry of Agriculture and Rural Affairs. Compared with the conventional rice harvester, the yield loss rate, impurity content and crushing rate of the specialpurpose harvester could meet the requirements of the industry standard, the directrolling rate was reduced by about 50%, the minimum ground clearance was higher than that of the conventional rice harvester, the average grounding pressure was slightly higher than the requirements of industry standard. In the aspect of operation economy, operation efficiency, fuel consumption and operation cost were basically equal to those of conventional rice harvesters. The second rice heading rate of the plots harvested by special harvester was slightly higher. In addition, in view of the development of the integration of machine and technology, the paper puts forward specific measures to speed up the whole machine structure optimization, reduce the rolling rate and enhance the information technology.

Key words: ratooning rice harvester, operation effect, performance test, production assessment
