Provided is a working vehicle configured so that, when starting up the working vehicle, the temperature of operating oil for a clutch can be increased without using a torque converter. A working vehicle is provided with a transmission, an operating oil supply circuit, an operating oil warming circuit, and a control unit. The operating oil supply circuit supplies operating oil to the transmission. The operating oil warming circuit warms the operating oil. The control unit controls the transmission, the operating oil supply circuit, and the operating oil warming circuit. The transmission includes a hydraulic clutch and a clutch control valve. The clutch control valve controls the pressure of the operating oil supplied to the hydraulic clutch, the control being performed according to a command from the control unit. Upon determining that the temperature of the operating oil is low, the control unit outputs a warming command for operating a warming function. The operating oil warming circuit causes pressure loss to be generated in a flow passage for the operating oil and warms the operating oil. |
