The development of the agricultural machinery is directly related to the economic conditions of the country and the countryside. In the economically developed countries, especially in the United States, where the agricultural labor force is very small, agricultural machinery continues to develop in the direction of large, wide, high speed and high productivity, and in the realization of mechanization on the basis of the gradual transition to the production process automation.
Electronic Technology, computer technology and other advanced science and technology in agricultural machinery products and its design and manufacture are increasingly widely used. In the animal husbandry industry, especially the chicken industry has entered the stage of continuous factory production, the closed henhouse with automatic microclimate control is a new development of animal husbandry machinery. In field machinery, the combination of hydraulic and electrical control, or direct use of electrical or electromagnetic control of automatic control devices have begun to apply, such as the Grain Combine Harvester on the platform of the lifting control and the reel speed, such as stepless. There are a growing number of electronic monitoring instruments, such as the uniformity monitor on the planter, the grain loss monitor and the drum speed monitor on the combine harvester, and the spraying and spraying monitors on the sprayer. Electronic technology is increasingly used in automatic classification of vegetables and fruits, automatic management of field irrigation and other mechanical equipment.
