To provide a working vehicle capable of adding a driving speed difference between right and left traveling devices to the speed of an operating vehicle, and suppressing the manufacturing cost to a low level, concerning a working vehicle which includes a control part for operating the vehicle speed of a traveling machine body having a pair of right and left traveling devices.

The working vehicle includes the traveling machine body 6 which is travelled and driven by the pair of right and left traveling devices 1, 1. The vehicle is provided with each transmission formed by combining a hydraulic pump with a hydraulic motor 30, respectively on each of the right and left traveling devices 1, 1, and with each operation lever for performing speed-change operation of the transmission respectively on each transmission. The working vehicle also has the control unit for operating the vehicle speed of the traveling machine body 6. The vehicle is further provided with each operation position detection means for detecting then operation position of the operation lever, respectively on each of the pair of transmissions, and the control unit operates the vehicle speed of the traveling machine body 6 from the engine rotation frequency and the operation position of the operation lever.
