Agricultural machinery chassis is an important part of agricultural equipment, and its technological development reflects the degree of mechanization and intelligent development of agricultural equipment. Based on the analysis of the agricultural machinery chassis technology development worldwidely, the chassis of transmission system, driving system, steering system, braking system and chassis remote controlling were proposed. The latest researches on agricultural machinery chassis in fourwheel drive, continuously variable transmission, adjustable wheelbase, air suspension and suspension drive axle, steerbywire, braking and antiskid were summarized. Meanwhile, the basic principles and characteristics of the relevant technologies of each system were expounded combining with the agricultural machinery chassis of different application environments. Finally, considering the research progress and application demand of agricultural machinery chassis technology in China, the future research emphasis and development direction were as following aspects: strengthening basic theoretical research and key parts performance optimization, enhancing chassis platform and lightweight design, and realizing chassis intelligent control and information management.
