A work vehicle having a hydraulic control device, , comprising: a hydraulic pump that supplies pressure oil ; an arm drive actuator that drives, with pressure oil supplied from the hydraulic pump , an arm attached to the work vehicle so as to swing the arm; a bucket drive actuator that drives, with pressure oil supplied from the hydraulic pump , a bucket attached to a front end of the arm , so as to swing the bucket ; an arm drive pressure oil control valve that controls drive of the arm drive actuator by controlling pressure oil supplied from the hydraulic pump to the arm drive actuator ; a bucket drive pressure oil control valve that controls drive of the bucket drive actuator by controlling pressure oil supplied from the hydraulic pump to the bucket drive actuator ; an arm operation unit that controls the arm drive pressure oil control valve ; a bucket operation unit that controls the bucket drive pressure oil control valve ; an operating state detection unit that detects operating states of the arm drive actuator and the bucket drive actuator ; a flow control valve that restricts pressure oil to be supplied to the arm drive actuator as combined operation of the arm drive actuator and the bucket drive actuator is detected via the operating state detection unit ; an angle detection unit that detects an angle of the arm relative to the front body of the work vehicle ; and an angle setting unit that sets a specific angle for the arm , characterized in that once the operating state detection unit detects an operation of the bucket drive actuator combined with an operation of the arm drive actuator along an arm raising direction, the flow control valve starts restricting a quantity of pressure oil supplied from the hydraulic pump and flowing into the arm drive actuator only after the angle of the arm , detected via the angle detection unit, reaches the angle set at the angle setting unit. a hydraulic pump that supplies pressure oil ; an arm drive actuator that drives, with pressure oil supplied from the hydraulic pump , an arm attached to the work vehicle so as to swing the arm; a bucket drive actuator that drives, with pressure oil supplied from the hydraulic pump , a bucket attached to a front end of the arm , so as to swing the bucket ; an arm drive pressure oil control valve that controls drive of the arm drive actuator by controlling pressure oil supplied from the hydraulic pump to the arm drive actuator ; a bucket drive pressure oil control valve that controls drive of the bucket drive actuator by controlling pressure oil supplied from the hydraulic pump to the bucket drive actuator ; an arm operation unit that controls the arm drive pressure oil control valve ; a bucket operation unit that controls the bucket drive pressure oil control valve ; an operating state detection unit that detects operating states of the arm drive actuator and the bucket drive actuator ; a flow control valve that restricts pressure oil to be supplied to the arm drive actuator as combined operation of the arm drive actuator and the bucket drive actuator is detected via the operating state detection unit ; an angle detection unit that detects an angle of the arm relative to the front body of the work vehicle ; and an angle setting unit that sets a specific angle for the arm , characterized in that once the operating state detection unit detects an operation of the bucket drive actuator combined with an operation of the arm drive actuator along an arm raising direction, the flow control valve starts restricting a quantity of pressure oil supplied from the hydraulic pump and flowing into the arm drive actuator only after the angle of the arm , detected via the angle detection unit, reaches the angle set at the angle setting unit. <EOS>
