Abstract:
To provide a working vehicle capable of achieving further improvement of steering performance while suppressing enlargement and complexity of a structure thereof.SOLUTION: A steering device 10 provided on a working vehicle 1 includes: steering bodies 18R, 18L capable of being grounded on a ground surface G; a right steering mechanism 10R and a left steering mechanism 10L rotatably supporting the steering bodies 18R, 18L and making a braking force work on the ground surface G. The steering device 10 is structured to be changeable between a 'contact mode' of bringing the steering bodies 18R, 18L into contact with the ground G to such a degree as not to change a steering direction of the working vehicle 1 and a 'braking mode' of changing a traveling direction of the working vehicle 1 by making a braking force work on the ground surface G through the right steering mechanism 10R and the left steering mechanism 10L.SELECTED DRAWING: Figure 2
