PROBLEM TO BE SOLVED: To provide a working vehicle performing a turn excellent in improved work efficiency and work uniformity. SOLUTION: The working vehicle includes an angle detection means 51 detecting a rotation angle of a steering wheel 7 making a straight motion direction as reference, an angle-threshold setting means 61 setting a threshold A of the rotation angle of the steering wheel 7 that is the reference of the start and/or end of control of working speed and turning speed, a turning-vehicle-speed setting means 62 setting the set-turning-vehicle speed V when the steering wheel 7 is positioned at the threshold A of the rotation angle or more, a transmission actuator 24 of a hydraulic continuously variable transmission 23, and a control means 81. The control means 81 operates the transmission actuator 24 to make the speed the set-turning-vehicle speed V when the value detected by the angle detection means 51 becomes the threshold A of the rotation angle or more, and controls the transmission actuator 24 to make the speed the working speed when the value detected by the angle detection means 51 is less than the threshold A of the rotation angle.
