PROBLEM TO BE SOLVED: To provide a combine harvester capable of carrying reaped grains-with-stems to be in threshing posture such that their tips of ears go ahead a little of their stump parts, even the action speed of a grain-with-stem raising-up device 223 is changed relating to the properties and the like of unreaped grain planted and standing in the field, thereby being made able to improve the carrying performance of a grain-with-stem carrying means 34. SOLUTION: The combine harvester provided with a travelling machine body 1 equipped with a travelling part 2 actuated by an engine 14, the grain-with-stem raising-up device 223 taking in grains-with-stems planted and standing in the field, a reaping blade device 222 for cutting the stump parts of the grains-with-stems planted and standing in the field, and the grain-with-stem carrying means 34 for nipping and carrying the grains-with-stems, of which stump parts have been cut by the reaping blade device 222; is constituted by being provided with an electric motor 92 for longitudinal carrying drive for actuating the grain-with-stem carrying means 34 and a raising-up speed sensor 291 for detecting the actuation speed of the grain-with-stem raising-up device 223, so as to change and control the rotary speed of the electric motor 92 for longitudinal carrying drive, based on the detection result of the raising-up speed sensor 291.
