A working vehicle includes front wheels Wf steered by a steering wheel , and rear wheels Wr driven through a transmission system T incorporating static hydraulic pressure type continuously variable transmissions. A speed change operating device M for controlling speed change of the transmission system T accelerates or decelerates right and left rear wheels Wr at same rotating speed by operation of a change lever , and also generates a difference in rotating speed between the right and left rear wheels Wr by operation of the steering wheel . The steering characteristic on the basis of operation of the steering wheel varies depending on the vehicle speed set by the change lever , so that an appropriate steering characteristic may be obtained if the vehicle speed is changed.

A working vehicle includes an engine in the rear of a passenger seat, and a working machine vertically movably disposed in the rear of the engine, wherein an upper end of the working machine which is lifted to the highest position is set lower than an upper end of the engine. As a result, a ventilation in the vicinity of the engine is improved and a cooling effect of the engine is enhanced. Also, a maintenance of the engine can be conducted without being interfered by the working machine. Further, with this arrangement, a center of gravity of the working machine is low, thereby enhancing a stability of the working vehicle, and a driver or a passenger of the vehicle can visually check backward much easier.
