PROBLEM TO BE SOLVED: To largely reduce power loss in a traveling vehicle formed to transmit the power of an engine mounted on a traveling frame to left and right traveling parts through a hydraulic continuously variable transmission 50 and having a main shift lever 13, a steering wheel 10, and an auxiliary shift lever 14. SOLUTION: This traveling vehicle comprises electric motors 151, 161 for regulating the transmission output of the hydraulic continuously variable transmission 50, a controller 170 for controlling the driving of the electric motors 151, 161, and a PROM 172 in which a transmission output pattern is stored beforehand. The controller 170 regulates the transmission output of the hydraulic continuously variable transmission 50 by so driving the linear traveling electric motor 151 and the rotating electric motor 161 that the speeds of left and right traveling crawlers are equal to the values obtained from the information detected by a steering position sensor 117 and a main shift position sensor 135 and the transmission output pattern selected according to the operating state of the auxiliary shift lever 14.
