From "feeding on the sky" or even "slashing and burning cultivation" to "all-round and whole-process mechanization", China's agricultural mechanization has developed continuously, and has taken a road with Chinese characteristics.

From 1949 to 1980, the central government put forward clear agricultural mechanization development goals and corresponding guidelines and policies. Agricultural machinery stations were set up in qualified societies and teams to support the mass agricultural tool reform movement. China's agricultural machinery industry starts from manufacturing new agricultural machinery and tools, and develops gradually from scratch.

From 1981 to 1995, the household contract responsibility system was implemented in rural areas. Collective farm machinery stations were gradually disbanded. The state began to allow farmers to buy and operate farm machinery independently. Farmers gradually became the main body of investment and operation of agricultural machinery. In order to adapt to the major changes in agricultural production organization, the agricultural machinery industry began the first round of large-scale structural adjustment, focusing on the production of small-scale agricultural machinery, walking tractors, agricultural by-products processing machinery, agricultural transport vehicles and so on. Large and medium-sized tractors and supporting farm tools have stagnated, the matching ratio of machines is out of balance, the utilization rate of field machinery is low, and the level of mechanization of farm operations has been slowly improved.

By the mid-1990s, a large number of rural labor force began to shift, and the trend of seasonal labor shortage in rural areas continued to emerge. Relevant ministries and commissions of the state began to organize large-scale cross-regional wheat harvesting services. The utilization rate and operating efficiency of combine harvesters were greatly improved. Effective ways to solve the contradiction between small farmers'production and large-scale operation of agricultural machinery were explored, and the road of development of characteristic agricultural mechanization was initially formed. Agricultural machinery industry has also ushered in a new round of product restructuring, high-efficiency large and medium-sized agricultural machinery began to recover growth, the growth rate of small agricultural machinery slowed down, combined harvester emerged, once became the pillar industry of agricultural machinery industry development.

In fact, the renewal and replacement of agricultural machinery is a microcosm of the development process of agriculture in China. Only from scratch, and the gradual diversification of tractors, have confirmed the development and changes of agricultural machinery in China, even the whole of China's agriculture from one side.

Since the Eighteenth National Congress of the Communist Party of China, the pace of agricultural scientific and technological innovation has obviously accelerated, and the Rural Revitalization has inserted the wings of science and technology. Take tractors as an example. At present, domestic self-driving and unmanned tractors have been developed successfully. The Chinese Artificial Intelligence Association predicts that by 2030, unmanned tractors will be popularized in rural areas of China. Compared with the era when tractors were "rare things" 70 years ago, the development of Agricultural Mechanization in China can only be described as "great changes".
