Abstract
A working vehicle such as an agricultural tractor includes a control device having an accelerating drive mode to accelerate front wheels automatically to rotate faster than rear wheels when the front wheels are steered in excess of a fixed amount. When the rotating speed of an engine falls below a predetermined value, a shift to the accelerating drive mode is inhibited to avoid an engine stall.
