摘要： The work vehicle is provided with an operation section having a steering wheel for steering the traveling sections mounted through a steering wheel support shaft coupled operatively with a steering link mechanism system built in a link box that in turn is operatively coupled with a trunnion arm member of a cornering non-stage shift system for accelerating or decelerationg a rotational velocity of a cornering power transmission system to associate an operation of the steering wheel for left-hand or right-hand rotation with an operation fo the cornering non-stage shift system for normal rotation or reverse rotation. With the structure and action, the work vehicle can ensure a favorable operating performance.
