The present invention relates to a steering apparatus for an agricultural transport vehicle having an automatic alignment function and, more specifically, to a steering apparatus for an agricultural transport vehicle, which includes driving motors provided to be connected to front wheels and rear wheels of a chassis frame, respectively, to separately drive the front wheels and the rear wheels, and axle bodies provided at the front and rear portions of the chassis frame to rotate the front wheels and the rear wheels, respectively. The present invention provides the steering apparatus for the agricultural transport vehicle, comprising: front and rear side cylinders provided to be fixed in the chassis frame; cylinder rods provided to enter and exit both sides of the cylinders and having both ends connected to both front wheels and both rear wheels, respectively; a chain bracket fixed to the front side or the rear side cylinder rod to move along with the cylinder rod; a chain provided to fix both ends to the chain bracket; a driving wheel rotatably provided in the chassis frame and provided to get the chain to be caught on the outer circumferential surface; an encoder provided in the chassis frame to sense the rotating direction and the rotation amount of the driving wheel; and an ECU reading a value sensed and detected by the encoder to reversely operate each of the cylinder rods such that the front wheels and the rear wheels are automatically aligned in a straight driving state.
