PROBLEM TO BE SOLVED: To provide a traveling crawler for a combine having less vibrations. SOLUTION: In the combine controlling rolling of a vehicular body by ascending/descending adjusting a right side traveling crawler alone, when a horizontal state that a left side traveling crawler 3 provided in fixed state at a specified position and the right side traveling crawler 3 are in the same level is made by ascending/descending the right side traveling crawler 3 to the specified position, right and left first front rolling wheels 30b, 30a following right and left driving sprockets 28, 28 on which the right and left traveling crawlers 3, 3 are wound are structured to be shifted in a back-and-forth direction at a specified interval. The deviation in the back-and-forth direction at the specified interval is structured to be same as an interval between reinforcing cores 35 provided on the right and left crawlers 3, 3 at specified intervals. The right and left first front rolling wheels 30a, 30a alternately run on the cores 35, 35 of the right and left crawlers 3, 3, thereby decreasing vibrations at traveling on a road.
