TRAVELING DEVICE FOR WORK WAGON

PROBLEM TO BE SOLVED: To optimally cope with backward driving reactive force, to simplify an operation and to improve operability and work efficiency. SOLUTION: The traveling frame 5 of a traveling device 2 where a pair of right and left crawlers 7 is provided in the lower part position of a machine body frame 1 so as to be freely rolling possible by elevating/lowering and also a pitching means 26 which elevates/lowers the front or the rear side of the machine body frame 1 is provided in the traveling device. The device is constituted by providing an ill-drained paddy state selecting means for changing a control mode into an ill-drained paddy mode in a control part and by elevating the advance direction front side of the machine body frame 1 so as to correct foreward and backward inclination with backward driving reactive force. Controls is executed so as to permit a cutting part provided at the front side of the traveling device 2 to be positioned in the neighborhood of the most upper part position.
