Abstract: Intellectualization is the orientation of tractors products. Intelligent agricultural tractors have become a research hotspot in agricultural machinery. Based on the research of intelligent agricultural equipment, this paper puts forward the definition of intelligent agricultural tractors and expounds the key characteristics of intelligent agricultural tractors. This paper analyzes the research progress of key technologies such as automatic navigation, automatic shift, control system and intelligent farming system, and points out that driverless technology, networked cloud control, precision control and intelligent terminal will be the orientation of intelligent agricultural tractors. Also, intelligent agricultural tractors are the key carrier of intelligent agricultural technology. There are many researches on intelligent tractors in China, but the research level of intelligent control terminal, remote networked control, control accuracy and reliability of intelligent tractors in China lags far behind that in foreign countries. Domestic tractors manufacturers should speed up the research on key technologies, seek breakthroughs in the development of intelligent tractors, and promote the development of highquality and efficient agricultural mechanization.

Key words: intelligent agricultural equipment, tractor, satellite positioning；automatic driving, precise control
