PROBLEM TO BE SOLVED: To reduce a load in a hydraulic system of a working vehicle.SOLUTION: A working vehicle comprises: a lifting/lowering mechanism (3) that is supported by a vehicle body (2) so as to be able to lift/lower a working device (4) that is supported by the lifting/lowering mechanism (3) and performs work in a field a lifting/lowering hydraulic actuator (33) that lifts/lowers the lifting/lowering mechanism (3) an oil tank (12) that stores hydraulic oil an oil feed pump (56) that feeds the hydraulic oil from the oil tank (12) to the lifting/lowering hydraulic actuator (33) a lifting/lowering detection member (SN1) that detects lifting of the lifting/lowering mechanism (3) and oil feed control means (C9) that increases an amount of the oil to be fed by the oil feed pump (56) to the lifting/lowering hydraulic actuator (33) when the lifting/lowering detection member (SN1) detects lifting of the lifting/lowering mechanism (3).
