PROBLEM TO BE SOLVED: To provide a posture control device of an agricultural working vehicle capable of quickly performing a posture changing operation. SOLUTION: This device is provided with four driving means capable of freely changing a space between a grounding part of each traveling device and each of a left side front part, a left side rear part, a right side front part and a right side rear part of a machine main body. Target driving speed for correcting front and rear inclination and target driving speed for correcting left and right inclination are determined for each of the driving means in a form that each of the driving speed is increased as the deviation of a front and rear inclined angle from a left and right inclined angle becomes larger, while maintaining a state in which each of the four grounding parts is located on imaginary plane so that target front and rear inclined angle and target left and right inclined angle may be provided, while simultaneously correcting the front and rear inclined angle and the left and right inclined angle. By summing up the driving speed, total target driving speed for each of the driving means is determined. A driving operation processing for driving each of the driving means at the total target driving speed is executed. COPYRIGHT: (C)2006,JPO&NCIPI
