To provide a relatively inexpensive working vehicle capable of making a small turning circle in a simple structure.

The working vehicle is provided with two running wheels 3, 3a and two floating wheels 4, 4a arranged at front and rear and left and right of a machine body 2 on which a working machine is mounted and supporting the machine body 2, an engine 5 for driving the running wheels 3, 3a, a power transmitting mechanism 6 for interlockingly connecting the engine 5 with the running wheels 3, 3a, and a steering handle 7 for steering the machine body 2. The running wheels 3, 3a, the engine 5, and the power transmitting mechanism 6 are formed into a unit A capable of turning the engine 5 and the power transmitting mechanism 6 with respect to the machine body 2, and the unit A is pivoted to the machine body 2 to be turnable around a vertical axis 8, so that the small turning circle can be made.
