PROBLEM TO BE SOLVED: To provide a seeding machine capable of changing over a number of rows for sowing the seeds between one and two in accordance with the sown seeds. SOLUTION: This seeding machine has a hopper, a feeding device, furrow openers, a covering plate, and a packing roller, wherein the feeding device has a feeding roll on which sowing channels are zigzag arranged, so that the seeds discharged from the sowing channels are distributed into two of the right and left parts. Further, a guide tube for conducting two-row sowing, or another guide tube for conducting one-row sowing after gathering the distributed parts of the seeds, is mounted on the seeding machine together with the furrow openers, so that the one-row sowing and the two-row sowing are changed over only by exchanging the guide tubes and attaching/detaching one of the furrow openers to/from the seeding machine.
