The humanized and less humanized operation is still the main working mode of the current mechanized operation. As the core common component of the highend agricultural machinery, the integrated intelligent console is widely used in tractors, sprayers, harvesters and other large agricultural machinery equipment. As a medium of direct contact with the driver, it has a direct impact on the physical and mental health of the driver. Aiming at the problem of high strength and high psychological load of manual operation, and the requirements of operators’ active health, the domestic typical console was selected. Based on Kansei engineering theory,the psychological load index system was constructed, and the static manmachine semiphysical test of tractor intelligent console was carried out. The principal component model of psychological load was established, and the console based on minimum psychological load was optimized. Firstly, the psychological load evaluation system was constructed, and the manmachine semiphysical test bed was built based on the domestic large tractor. The actual driving video of ploughing condition was selected and the test scheme was designed. Secondly, totally 10 drivers with tractor driving experience were selected to test and record the psychological load index data. Thirdly, the principal component model of psychological load was established according to the experimental data, and the design defects of the psychological load of the console before optimization were analyzed. Finally, based on the results of principal component analysis, in order to minimize the psychological load, the manmachine engineering theory was applied to optimize the console from the aspects of interface element distribution, element color and shape. The optimized console was obtained and then verified by experiments.The results showed that the psychological load of the driver was mainly composed of fatigue perception factors and fatigue mitigation factors. The average psychological comfort score of the console before optimization was 0.403. The main fatigue perception factor was visual and neck fatigue (weight: 0.458), and the main fatigue mitigation factor was job selfefficacy (weight: 0.578). The average score of the optimized console psychological comfort was increased to 2.048, which can significantly alleviate the psychological load. The research results can provide some reference for the design of comfort of intelligent tractors, and it can help to improve the design theories of agricultural machinery equipment active health.
