PROBLEM TO BE SOLVED: To provide a traveling vehicle which can surely perform restart of an engine by reducing a load of a hydraulic continuously variable transmission in the case of restarting the engine from an idling stop state, so as not to lower the durability of the engine 20.SOLUTION: In this working vehicle, an unload valve 84 for switching a direction of hydraulic oil between a direction of feeding to hydraulic circuits Y, Z and a direction of returning to an oil tank 12 is disposed in an oil passage between a main pump 86 and the hydraulic circuits Y, Z and when a control device 100 restarts an engine from an idling stop state, the unload valve 84 is actuated so that the working fluid is returned to the oil tank 12 during a predetermined time, and further after the lapse of a predetermined time, the working fluid is fed to the hydraulic circuits Y, Z.
