PROBLEM TO BE SOLVED: To provide a turning control device for a working vehicle such as a tractor as improvement of a conventional arrangement configured so that the turning mode is set by a setting device, in which once the turning mode is set, an excessive steering is made owing to functioning of the turning mode even when the vehicle avoids an obstacle or meanders largely along the shape of a field, presenting a problem on the easiness in operability. SOLUTION: The turning control device of the working vehicle is equipped with a sensor to sense the height of the working vehicle, a transmission device to change over the turning mode of the tractor into a mild turn in which the rotation of a running device inside of turning is decelerated, a lock turn in which the rotation of the running device inside of turning is stopped, and a spin turn in which the rotation of the running device inside of turning is reversed, and the turning mode setting device to set the turning pattern appearing when a steering handle is turned to the maximum. A controller changes the turning mode set by the mode setting device in accordance with the height of the working machine. COPYRIGHT: (C)2006,JPO&NCIPI
