Abstract:
A work vehicle in which a driving force is transmitted to left and right travel crawlers (2) through a transmission member (25) for changing the traveling speed continuously by operating a travel transmission lever (73), and a steering member (28) is controlled by a steering wheel (19) to change the difference between the driving speeds of the left and right travel crawlers (2) continuously. The vehicle speed determined by the control input of a travel transmission lever (73) is decelerated in proportion to the control input of the steering wheel (19), and the reduction ratio of the vehicle speed to the control input of the steering wheel (19) can be changed.
