Provided is a work vehicle that does not have any torque converter, and that can raise the temperature of the hydraulic oil of a clutch when the work vehicle starts. The work vehicle includes a transmission, a hydraulic oil supply circuit, a hydraulic oil warming circuit, and a control unit. The hydraulic oil supply circuit is configured to supply hydraulic oil to the transmission. The hydraulic oil warming circuit is configured to warm up the hydraulic oil. The control unit is configured to control the transmission, the hydraulic oil supply circuit, and the hydraulic oil warming circuit. The transmission includes a hydraulic clutch and a clutch control valve. The clutch control valve is configured to control the pressure of the hydraulic oil supplied to the hydraulic clutch according to a command from the control unit. When the control unit determines that the temperature of the hydraulic oil is low, it is configured to output a warming up command for operation of a warming up function. And the hydraulic oil warming circuit is configured to warm up the hydraulic oil by causing the pressure loss in a flow path for the hydraulic oil. |
