Abstract

PURPOSE:To enlarge the scope of correction of inclination of a tractor body, by providing a mechanism which can automatically change one of cylinders that has attained the stroke end to be used as a posture control reference so that other cylinders are controlled. CONSTITUTION:In the cylinders 10A through 10D that move vertically the tractor body and are attached to respective wheels, A through D are provided in mechanism for detecting the stroke end. The signal from the detecting mechanism 12 is transmitted to a standard selection mechanism 13. The mechanism 12 changes automatically one of the cylinders that has attained the stroke end to be used as a posture control reference and transmits it to a controlling mechanism 14. The controlling mechanism 14 together with a signal from an inclination detecting mechanism 11 judges the inclination of the tractor body and controls the particular hydraulic cylinder through one of control valves V1 through V4. Since the cylinder that has attained the stroke end is used as the posture reference, the scope of control of the inclination becomes double of the prior art.
