PROBLEM TO BE SOLVED: To provide a combine harvester capable of performing the reaping in a middle-separated reaping form as reaping four rows by a simple structure and also suppressing the formation of high stumps. SOLUTION: In the combine harvester, the interval W1 between the tip ends 12c, 12b of a middle grass-separating tool 12C and an outer grass-separating tool 12R at an operating part side with each other, and an interval W2 between the tip ends 12a, 12c of an outer grass-separating tool 12L at the opposite side to the operating part side and the middle grass-separating tool 12C with each other, are provided at intervals capable of introducing planted cereal culms (a) of 2 rows, and engage-linking a raking ring body 16b raking the root part side of the planted cereal culms (a) from the middle grass-separating tool 12C and the outer grass-separating tool 12R at the operating part side into a reaping device 15, and a raking ring body 16a raking the root part side of the planted cereal culms (a) from the middle grass-separating tool 12C and the outer grass-separating tool 12L at the opposing side to the operating part side into a reaping device 15. A position Z where the pair of raking-in ring bodies 16a, 16b engages, is deflected to the side of positioning the operating part 20 from the position of the tip end 12c of the middle grass-separating tool 12C.
