摘　　要：统计分析了近10年来国产拖拉机的年产量和保有量。对国内7家拖拉机制造企业生产的35种新开发的拖拉机的性能进行了检测,统计了国产拖拉机比质量、油耗、振动、噪声和牵引性能的技术现状,并与欧美国家拖拉机进行了对比分析。分析结果表明,国产拖拉机在燃油经济性、振动和噪声方面与欧美发达国家还存在较大的差距,建议对电喷发动机、无级变速传动系、驾驶室和悬架系统进行系统研究,以尽快提高国产拖拉机的性能。The annual production and quantity of domestic tractors in recent 10 years are analyzed. The performances of 35 kinds of tractors produced by 7 domestic tractor manufacturing enterprises are tested. The key performance index such as the specific dry mass ,fuel economy, vibration, tractive performance are not only counted and analyzed, but compared with the developed countries. The analysis results show that domestic tractor has wide gap with the developed countries in fuel economy, vibration and noise. To improve the performance of domestic tractor, the electronic fuel injection engine, continuously variable transmission system,the cab and suspension system should be studied.
