Abstract:
[Problem] To provide a working vehicle in which a vehicle body can be turned at a turning radius according to the area of a turning location or the position of the vehicle body after turning. [Solution] A left-side HST33 and a right-side HST34 are provided corresponding to left and right-side travel devices 12, respectively. Power is transmitted from the left-side HST33 and the right-side HST34 to the corresponding travel devices 12, whereby a vehicle body 11 supported by the travel devices 12 travels in a straight line and turns. A steering lever 22 is provided to switch between straight-line traveling and turning of the vehicle body 11. In addition, a turning ratio changing trigger 28 is provided in the steering lever 22. When the steering lever 22 is manipulated from a straight-line traveling position to a turning position, a turning ratio is generated between the inside-turning travel device 12 and the inside-turning travel device 12, and the vehicle body 11 turns at a turning radius according to the turning ratio. When the turning ratio changing trigger 28 is manipulated during the turning of the vehicle body 11, the turning ratio changes to a value according to said manipulation.
