PROBLEM TO BE SOLVED: To provide a combine effective for preventing grains on a first grade grain screw from dropping on a tailing screw. SOLUTION: A feed chain of the combine is connected to the downstream of a culm transporting apparatus to transport reaped culms while controlling the threshing depth. The feed chain is attached in a state turnable and openable around a rotary shaft relative to the machine body. The threshing apparatus 15 contains a shaking shelf 51 to shake the treating object containing threshed grains and separate the object. A dust exhaustion rack 107 placed on the swinging shelf 51 is made to be attachable and detachable, to and from the shaking shelf 51 when the culm transporting apparatus is opened relative to the body. The dust exhaustion rack 107 is attachable to both side walls of the shaking shelf 51 when the feed chain is opened to facilitate the attaching and detaching work of the dust exhaustion rack 107 to the shaking shelf 51 and the maintenance and inspection of the dust exhaustion rack 107, etc.
