Abstract
An arrangement is provided in which the durability of an operation changing means is improved when this means is provided to the suspension mechanism in a suspension structure for a work vehicle. A maximum position (A) and minimum position (A) of the operation of the suspension mechanism are detected, and an intermediate position (B) between the maximum and minimum positions (A) and (A) is detected. When the intermediate position (B) departs from the target range (H), the operation of the suspension mechanism is changed to the body raising side or body lowering side so that the intermediate position (B) moves toward the target range (H).
