PROBLEM TO BE SOLVED: To facilitate the changing of inclination and an absolute horizontal posture by the manual operation of an operator during agricultural work by presetting only a car height. SOLUTION: A set car height value is stored beforehand in a car height setter (S1) and, when an operation lever is operated (S2: yes), left and right inclining posture control values at the end of this operation are stored in an inclined value storing means, inclining posture control is executed according to the left and right inclining posture control values stored at the end of the operation, and a car height is changed (S3). When a horizontal setting switch is turned ON while the operation lever is not operated (S2: no, S4: ON), horizontal posture control is executed for setting a traveling machine to be horizontal left and right (S5), and when the horizontal setting switch is OFF (S4: OFF), control is executed to hold the inclining posture at the end time of the operation of the operation lever, and priority is placed on the control of a horizontal or inclining posture (S5, S6) rather than on car height control (S8).
