Abstract: Tractor is one of the important agricultural machinery in agricultural production,is to ensure that the agricultural production operations are carried out smoothly one of the agricultural machinery,and other agricultural machinery to cooperate to complete the various operations in the field link. Driverless tractor is installed on the tractor through the positioning system,through the global positioning system can accurately determine the location of the tractor,the tractor on the camera to send back the picture displayed on the monitor,the operator can achieve remote control by watching the screen. This study introduces the development status and key technologies of driverless tractors at home and abroad,and analyzes the specific advantages of driverless tractors in agricultural change,and finally,proposes the promotion measures and methods of driverless tractors in agricultural applications to provide technical basis and development strategies for the application of driverless tractors in agricultural production.
