PROBLEM TO BE SOLVED: To provide a combine harvester easy/sure in route-changing operation with a route-changing means set on a rotation type steering operation implement and capable of preventing misoperation by switching spin rotation. SOLUTION: The rotational output of a hydraulic non-stage transmission (40) for rotation is formed to be able to control by a steering operation implement (16) having a monitor at the center. Wherein, when rotating the steering operation implement (16) right or left, a wheel shaft (30) in the rotating operation side is decelerated to turn and when more rotating the steering operation implement (16) in a state of spin rotation operated by operation of a steering other than the steering operation implement (16), right and left wheel shafts (30, 30) are each reversely rotated to perform spin rotation and the rotating operation state of the steering operation implement (16) is displayed on a display (22). And a route changing means (17) capable of adjusting the body right or left without rotating operation of the steering operation implement (16) is provided. COPYRIGHT: (C)2007,JPO&INPIT
