Abstract
A working vehicle is provided for improving safety and work efficiency by changing a travel speed limit appropriately depending on forms and conditions of work. The working vehicle is driven with an engine, and a working machine such as a working pump is mounted on the vehicle. Fuel supplied to the engine is regulated by an injector. Travel speeds of the working vehicle are detected with a vehicle speed sensor. A control unit is provided with a high speed travel mode which limits vehicle speed at or below a predetermined high speed limit and a low speed travel mode which limits vehicle speed at or below a low speed limit which is set below the high speed limit. In this way, either the high speed travel mode or the low speed travel mode is set according to a changeover signal from a travel mode changeover switch.
