With the development of China's agricultural mechanization and rural economy, small tractors have become the main driving force for agricultural operation and rural transportation, and their ownership has increased year by year. From the Eighth Five Year Plan period to the end of 1994, there were more than 8.18 million small tractors in China. During the Ninth Five Year Plan period and for some time thereafter, small tractors still increased at an annual rate of 2.7%. How to ensure that such a large number of small tractors can give full play to their due efficiency and make new contributions to the development of rural economy is an urgent problem to be solved.

Small tractors are welcomed by farmers because of their small size, flexibility, low price and wide application. Most of them are owned by individuals, so improving the user's use level has become a key factor to ensure the normal operation of small tractors. In order to help small tractor users and professional maintenance personnel correctly maintain and repair the locomotive, we have compiled this small tractor maintenance diagram, which uses the physical operation diagram instead of the lengthy text description to visually guide various maintenance operations. Intuitive and clear.

Due to the different models of small tractors and many places of origin, it is impossible to introduce them one by one in this book. Fortunately, the maintenance methods and principles are the same, so we can only replace the surface with points, select representative common models and introduce them by analogy.
