PROBLEM TO BE SOLVED: To provide a combine harvester effective for preventing accumulation of straw dust and weed at an inlet part of a thresher and preventing transportation failure and clogging of culm at the inlet part of the thresher. SOLUTION: The combine harvester is provided with an inlet funnel 20 at the culm inlet part of the thresher 5, a rake-in device 21 having a lug belt 29 passing through an opening 20a opened at the side end of a culm tip transporting part of the inlet funnel 20, freely movable upward from below the inlet funnel 20 and raking clogging materials including straw dust and weed, and interlocking mechanisms (14, 26, 28, 32) to interlock a rake-in device 21 and a reap supporting arm 13 in a manner to move the rake-in device 21 above the opening 20a of the inlet funnel 20 interlocked in connection with upward motion of the reap supporting arm 13 to liftably support the tip end of the reaping device 4. When the reap supporting arm 13 is moved upward, the rake-in device 21 is automatically moved above the opening 20a and the straw dust and weed are transported to the threshing device 5 by the movement of the lug belt 29.
