PROBLEM TO BE SOLVED: To improve traveling performance in a field, to simplify a transmission structure and to improve transmission efficiency by enabling the drive of steering wheels in a combine harvester equipped with a wheel travel apparatus.SOLUTION: A first output shaft 20 connected to a transmission system to one of wheel pairs positioned right and left and a second output shaft connected to a transmission system to the other of the wheel pairs are supported on a transmission case of the transmission 3. A drive transmission tool 24 for transmitting power from the second output shaft to the other wheel pairs is arranged at a position off the lower side of an open area in the lower face side of a thresher in a plan view and in the back and forth direction along a lateral side face at a closer side to the central position of a vehicle body in the right and left direction of the thresher. |
