A harvester of a combine provided with a pair of rotating packers, wherein the cutting device is configured to rotate and cut the root of the planted grain culm on each of the left and right sides of a junction by the rotating packers. A plurality of disk-shaped rotary cutters are arranged side by side in such a manner that a plurality of adjacent rotary cutters vertically overlap each other, and the driving rotation direction of the rotary cutter located on the left side of the junction is located on the left side of the junction. The rotation direction of the rotary packer is set to be the same as that of the rotary packer, and the rotation direction of the rotary cutter located on the right side of the junction is set to be the same as the rotation direction of the rotary packer located on the right side of the junction.
