A working vehicle 1 includes front wheels Wf steered by a steering wheel 8, 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 10, and also generates a difference in rotating speed between the right and left rear wheels Wr by operation of the steering wheel 8. The steering characteristic on the basis of operation of the steering wheel 8 varies depending on the vehicle speed set by the change lever 10, so that an appropriate steering characteristic may be obtained if the vehicle speed is changed.
