PROBLEM TO BE SOLVED: To solve problems such that in a rolling-controlling device of a tractor, for detecting the inclination of an implement by the height difference of left and right lower links, a detection error (twist) of the link mechanism appears markedly caused by the height of the implement, a power exceeding the acting range of a rolling cylinder 6 is required, hydraulic or electric controlling parts are damaged, or a hydraulic pressure to the another actuator becomes insufficient. SOLUTION: This rolling-control device for maintaining a prescribed angle for the vehicle of the tractor has a constitution for correcting the values of the lower link height difference sensors for detecting the height difference in accordance with the height of the implement, and also regulating the setting range of an inclination setting tool for setting the left and right inclination of the implement as narrower than a stroke amount of the rolling cylinder 6.
