PROBLEM TO BE SOLVED: To provide a working vehicle equipped with a control device capable of stopping the vehicle without damaging a clutch disk, when detecting abnormal decline of an oil pressure in an oil pressure circuit without stopping an engine. SOLUTION: When a pressure of a hydraulic oil supplied to each operation cylinder 85, 87, 88, 91, 92, 95 of a forward/backward movement clutch D, a clutch E for switching a main transmission and a clutch F for switching a Hi-Lo transmission, which is detected respectively by each pressure sensor 112a-117, is lowered to the first set value P1 or lower as long as a prescribed time T1 or longer, it is determined that an abnormal state is generated, and traveling is stopped by stopping supply of the hydraulic oil to each operation cylinder 85, 87, 88, 91, 92, 95 of each clutch D, E and/or F.
