PROBLEM TO BE SOLVED: To manually actuate a grain discharge auger in such a manner that fine adjustment can be performed safely. SOLUTION: An operating lever 52 for an operation box is placed at the front end part of a lateral auger cylinder in a grain discharging auger of a combine, as a manual operation-directing means. A vertical auger cylinder is horizontally rotated with a turning actuator 28 by operating the operation lever 52. The lateral auger cylinder is vertically rotated by the action of a hydraulic cylinder 34. When these augers are directed to rotate in these ways, the action speed of the operation lever 52 is controlled by a controller 41 so that the speed is slow at the start of action, and it becomes rapid when the duration of the action becomes long.
