A work vehicle has a hydraulic source; a control valve that controls a flow of the hydraulic oil discharged from the hydraulic source; and an engine starting device for starting an engine, in which a control device has: a low-temperature state determination unit that determines whether a temperature state of a working fluid of a torque converter is a low-temperature state; and a clutch control unit that when it is determined by the low-temperature state determination unit that the temperature state of the working fluid is not the low-temperature state, controls the control valve in order to switch a lock-up clutch to a non-engagement state, and when it is determined by the low-temperature state determination unit that the temperature state of the working fluid is the low-temperature state, controls the control valve in order to switch the lock-up clutch to a engagement state.
