Research projects designed to improve the level of agricultural machinery and the technological level of agricultural mechanization is important. Application of agricultural mechanics, tractor automotive science, mechanical design, mechanical and other principles of the theory of the chassis of the crawler drive operating systems running a theoretical analysis and research, the main chassis plete the track work and mechanical parameters of the calculation. The use of Auto CAD, Pro E, such as engineering software plete the overall design of the chassis to the technical requirements of the task book. The main findings are as follows: (1) to track the overall structure of the chassis were analyzed bya number of special structure and installation method, which assumed bandwidth 353mm, track length of around 4300mm, gauge 1300mm, wheelbase 1600mm, track 468mm, such as high; (2) the design of the tracked vehicle's basic puting, including the driving force for , traction for 21kw, the average speed of movement in the 2~5km / h, etc.; (3) the design of tension on the track and its related terms, including the effective coil springs for 7, pitch 12mm, pitch 7mm, etc.; (4) calculated a relatively simple and their related hydraulic systems, including hydraulic pumps and hydraulic motor
