ある農作業車のクローラ走行装置。 Of the plurality of three groups of grounding wheels that guide the crawler belt 4 to the ground, the intermediate portion in the longitudinal direction is configured as a movable grounding roller 3a of an internal rolling type that can move up and down, and the rest are fixed external rolling wheels. Wide anti-derail members 5, 5 are provided at the front and rear of the movable earth-contacting roller 3a, respectively, and engage between the core protrusions 4a, 4a of the crawler belt 4. In a crawler traveling device for an agricultural vehicle in which the end of the wheel preventing member 5 on the movable ground rolling wheel side is curved upward to allow upward bending of the crawler belt 4, the width of the lower surface of the curved portion 5a is A crawler traveling device for an agricultural vehicle, which is formed to be narrower than the width of the lower surface of the substantially linear guide portion 5b where fixed ground wheels are present.
