Abstract
A working vehicle that uses the output of an internal combustion engine () as a working power and a traveling power includes an accelerator pedal () that increases a rotation speed of the engine () when depressed and a transmission () that shifts a rotation of the engine () and applies the shifted rotation to the traveling power. A speed ratio control device of the transmission () calculates a first target vehicle speed (Wne) according to the rotation speed of the engine (), calculates a second target vehicle speed (Wu) according to a depression amount of the accelerator pedal (), and controls the speed ratio of the transmission () on the basis of the smaller of these target vehicle speeds. As a result, a vehicle speed according to the depression amount of the traveling accelerator pedal () is obtained even when the internal combustion engine () rotates at high speed.
