PROBLEM TO BE SOLVED: To provide a combine harvester scarcely generating uneven non-reaped crops, and improving reaping performance by suppressing trouble of clogging with cut culm while improving durability of the machine. SOLUTION: A subsidiary cutter 14 is supported in a manner vertically movable relative to a traveling body 2 with three lifting frames extended forward from the traveling body 2 in a state parallelly arranged with spaces in lateral direction of the traveling body. Among these three lifting frames, the center lifting frame 13A positioned at the center side in the lateral direction of the traveling body is formed from a linearly-extending straight frame part 13a positioned between a transfer unit 11 and an axle case 25 positioned below the transfer unit 11, and a curved frame part 13b curvedly extending downward from a front end of the straight frame part 13a on a front side of the axle case 25 by a process to form a single frame member by bending work.
