Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a working vehicle capable of improving reliability to performance of a servo control device, and capable of easily operating a continuously variable transmission.SOLUTION: The servo control device 3 has a shuttle arm 33 for controlling a servo valve 13 by mechanically transmitting an operation position of a shuttle lever to the servo valve 13, a shift arm 37 for controlling the servo valve 13 by mechanically transmitting an operation position of a shift lever to the servo valve 13, and a feedback mechanism 14 for stopping a servo cylinder by mechanically controlling the servo valve 13 in a neutral position, when the servo cylinder reaches a position corresponding to the operation position of the shift lever in the travel direction set by the shuttle lever, by mechanically transmitting operation of the servo cylinder to the servo valve 13.
