The origin of agricultural machinery can be traced back to the era when simple farm tools were used in primitive society. In China, during the Yangshao culture period of Neolithic Age (about 5000 ~ 3000 BC), there was a primitive tool for farming-Leigang. In the 3rd century BC/KLOC-,people in Niu Geng used copper plowshares. By the Spring and Autumn Period and the Warring States Period in the 3rd century BC, there had been a series of iron and wooden farm tools for farming, sowing, harvesting, processing and irrigation. Around 90 BC, the three rows of cymbals invented by Zhao Guo, that is, three rows of drills, are still in use today. By the 9th century, a fairly complete animal-drawn plough share had been formed. In ancient books such as Qi Yaomin's Book (about 540), Jing Lei Jing (about 880), Wang Zhennong's Book (about 13 10) and Heavenly Creations (1637), it was used in agricultural production in various periods. In the west, the original wooden plow originated in Mesopotamia and Egypt, and the iron plow head was used around 1000 BC.

19 to the beginning of the 20th century is the era of the development and wide application of new animal-drawn agricultural machinery. 183 1 year, American C.H. McCormick successfully manufactured the horse-drawn harvester. 1836, the first horse-drawn grain combine appeared. During the period of 1850 ~ 1855, grain seeder, lawn mower and corn seeder were manufactured and popularized successively. At the beginning of the 20th century, tractors driven by internal combustion engines began to gradually replace livestock. As traction power, tractors are widely used in various field operations to drive various fixed agricultural machinery.

At the end of 1930s, H.G. Ferguson of Britain successfully created the tractor's farm tool suspension system, which made the tractor and farm tools form a whole and greatly improved the use and operation performance of the tractor. The suspension system of farm tools controlled by hydraulic system also makes the operation and control of farm tools more portable and flexible. Agricultural machinery and tools matched with tractors gradually changed from traction type to suspension type and semi-suspension type, which reduced the weight and simplified the structure of agricultural machinery and tools. Since the 1940s, combine harvesters in Europe and America have gradually changed from traction to self-propelled. In 1960s, harvesting machinery for fruits and vegetables was developed. Since 1970s, electronic technology has been gradually applied to the monitoring of agricultural machinery operation process, and gradually developed to automation of operation process.

In the early days of People's Republic of China (PRC), new animal-drawn agricultural tools were widely developed, such as step plows, hoes, seeders, harvesters and waterwheels. At the end of 1950s, China began to establish tractors and its supporting agricultural machinery manufacturing industry. Luoyang No.1 Tractor Factory was completed and put into operation on 1959. 1972 The boat tractor (tractor) successfully manufactured provided multi-purpose traction power for paddy fields in southern China, especially in hot fields where water accumulated all the year round. By the end of 1984, there were 854,000 large and medium-sized tractors, 3.298 million small and walking tractors, 350,000 agricultural vehicles, 6/kloc-0.50 million agricultural irrigation and drainage power machines, 5 15.7 million agricultural pumps and 655,438+057,000 large and medium-sized tractors. 2918,000 small tractors, 3,586/kloc-0 grain combine harvesters, 0/39,000 feed pulverizers, 388/kloc-0 rice mills, cotton ginning machines and oil presses, and 68/kloc total agricultural power. 1984, the mechanized farming area reached 524 million mu, accounting for 39% of the cultivated land area. The electromechanical irrigation area reached 376 million mu, accounting for 56.4% of the irrigation area.
