PROBLEM TO BE SOLVED: To stabilize posture and behavior of a machine body in turning travel. SOLUTION: The combine harvester has a travelling device 2 comprising a right and left pair of crawlers 3 installed on the machine body frame 1 at least through a rolling means L. The travelling device 2 acts to keep the machine body horizontal against to the slope of the travelling face detected by a slope sensor of a rolling means L. The leveling control is stopped when a steering means 32 which controls the travelling direction of the machine, is operated to either one of the right and left direction when a main shift lever which operates the travelling rate of the travelling device 2, is in a high speed range, and the level controlling is set to hold the height of the right and left crawlers 3 equal to the machine body frame 1 by actuating the rolling means L.
