Abstract
A working vehicle is provided which can be smoothly started with a large driving force, and uniformly conducts a various types of works even if a travel speed varies. A working machine such as a working pump, which is also driven by an engine for driving the vehicle, is mounted on the working vehicle. The power is transmitted from a crank shaft of the engine to wheels through a torque converter provided with a lock-up clutch and an automatic transmission. The crank shaft is also connected to a driving unit for driving the working pump through gears. A transmission ratio of the automatic transmission is set to a predetermined value corresponding with work modes J -J . In such a way, the work modes J -J are set according to characteristics of the work, in which there exists a predetermined relationship between a work amount and a vehicle speed. Therefore, fertilizer, sand, and chemicals can be appropriately and uniformly spread through a changeover of the modes.
