<p>Disclosed are an automatic gear-shifting system of an agricultural vehicle and an automatic gear-shifting method using the same. An automatic gear-shifting system according to an embodiment of the present invention includes a driving lever switch manipulating the a shuttle gear-shifting unit, which is for gear-shifting to move forward or backward, to move forward and backward and to be in neutral; a main gear-shifting switch to gear-shift a main gear-shifting unit for a primary gear shift; a position sensor to detect a manipulation position of a mechanical sub gear-shifting lever to gear-shift a sub gear-shifting unit for a secondary gear-shift; an automatic/manual mode selecting switch selecting a gear-shifting mode to control the gear shift in either an automatic or a manual mode; a control unit controlling the gear shift corresponding to a corresponding signal combination based on signals inputted from the driving lever switch, main gear-shifting switch, position sensor, and the automatic/manual mode selecting switch; and an actuator receiving the signals from the control unit when the automatic gear-shifting mode is selected and generating power to change a position of the sub gear-shifting lever.</p> |
