ABSTRACT:
With a hydraulic traveling vehicle, a controller is configured and arranged to switch a merging/diverging valve to a merging state when a working equipment is driven with the merging/diverging valve being in a diverging state and with turning of the hydraulic traveling vehicle being carried out, and when a required flow rate parameter for pressurized oil of the working equipment is greater than or equal to a prescribed threshold value, and to maintain the merging/diverging valve in the diverging state when the required flow rate parameter is less than the prescribed threshold value.
