PROBLEM TO BE SOLVED: To provide improved reliability of a working vehicle by enabling the working vehicle to travel at crawling speed that is slower than the usual minimum traveling speed without changing any structures in a conventional traveling power transmission system and external power extraction system. SOLUTION: In the working vehicle V in which working equipment 15 is mounted, a motor 20 for crawling speed traveling is driven by a hydraulic pump 14 for crawling speed traveling that is driven by an engine 1 through a flywheel PTO 12, thus enabling the working vehicle V to travel at the crawling speed by the hydraulic motor 20 through a transmission 4.
