The invention discloses an unmanned agricultural machine steering system. The system comprises a steering oil cylinder, a reversing solenoid valve, a solenoid valve control module and a processor, andfurther comprises a motor control module, a servo motor, an oil filter, a hydraulic oil tank and a gear pump, wherein an input end of the motor control module is electrically connected with an outputend of the processor, an output end of the motor control module is electrically connected with an input end of the servo motor, an output end of the servo motor is electrically connected with an input end of the gear pump, an output end of the hydraulic oil tank is connected with an input end of the gear pump; specific operation steps of the steering system are as follows, S1) receiving a steering command, and then entering a S2); and S2) judging whether an instruction angle value is received or not, if so, entering a S3), if not, returning to the S1) to wait for a steering command. The unmanned agricultural machine steering system achieves the effect of a proportional valve through cooperation of a servo motor and a gear pump, so steering control is more accurate, cost is low, the systemstructure is simplified, and maintenance is convenient.
