PURPOSE: To prevent the damage of a reaping section, etc., by restricting to raise the reaping section above a prescribed range when an automatic rolling control switch is switched-on and the reaping section is tilted on the traveling frame.
CONSTITUTION: The tilting state of a reaping section 5 is detected with a sensor 6 and a hydraulic driving mechanism for rolling operations is controlled. An upper limit switch SU is disposed at an intermediate position between the highest limit position and lowest limit position of the reaping section. When a switch for controlling automatic rolling operations is switched-on and the reaping section is tilted in the direction approaching the side of a cockpit 8 on the basis of the traveling frame, the combine is constituted so that the raising of the reaping section is stopped at the upper limit-restricting position on the switching-on of the upper limit switch.
