The utility model relates to a tractor steering mode control equipment, which belongs to the control equipment of the steering mode for a vehicle. The utility model is characterized in that: the utility model comprises a programmable controller, an electromagnetic valve and a control circuit positioned in the oil supplying pipe of the tractor. The control circuit comprises a switch circuit and an implementing circuit controlled by the steering mode. The input end of the programmable controller is connected with the switch circuit which can send the steering dictate, and the output end is connected with the implementing circuit controlled by the steering mode, which is used for completing the steering mode changing. The utility model has simple structure, which adopts the programmable controller to realize the automatic control for the steering mode of the tractor, making the choosing correct for the steering mode of the tractor with simple operation, moreover, the working efficiency of the tractor is improved. 一种牵引车转向模式控制装置，它属于一种机动车的转向模式的控制装置，其特征在于它包括一个可编程控制器、设在牵引车的供油管道中的电磁阀和控制电路；所述的控制电路包括一个开关电路和一个转向模式控制执行电路，在所述的可编程控制器的输入端连接有发出转向指令的开关电路，在所述的可编程控制器的输出端连接完成转向模式转换的转向模式控制执行电路。本实用新型结构简单，采用了可编程控制器实现了对牵引车转向模式的自动控制，使得牵引车的转向模式选择准确，操作简单，也提高了牵引车的工作效率。
