Abstract: [Objective] To realize the reasonable adjustment of tractor tire pressure under different working conditions and operating environment, to solve the problem that tire pressure cannot be adjusted during the current tractor operation, to slow down tire wear, and to prolong tire service life. [Method] The research team designed an inflation and deflation system to meet different tire pressures through statistical analysis of the ideal tire pressure state of the tractor under different working conditions. Among them, the working principle and implementation of the tractor tire pressure polymorphic control system were focused on the analysis, and the installation verification was completed. [Result] The system has four tire pressure modes: transport mode, medium tillage mode, rotary tillage mode and plow and harrow mode, which can meet the user’s demand for reasonable adjustment of tractor tire pressure. The system is simple and convenient to operate, the driver in the cab through the polymorphic switch can select different operating patterns corresponding to the standard value of tire pressure, under the control of the controller automatically adjust the tire pressure to adapt to the current operating pattern. Different operating environment to choose the corresponding reasonable tire pressure can improve the traction power 6%~8%, give full play to the tractor power, so as to play the tractor maximum traction, and can improve operating efficiency, reduce fuel consumption.
