Provided is a transplanter capable of making gas compacted by controlling a height dimension of a height adjusting device having an ascending cylinder and a rolling cylinder. A link (3b) is supported on a piston rod (10a) of the ascending cylinder (10), and connection arms (51b, 51b) are installed in both left and right ends of the link (3b). Left and right ascendance adjusting rods (3a, 3a) for adjusting heights of left and right support wheels (3, 3) are connected with the connection arms (51b, 51b). The link has a balance earth axis (51a) for supporting the piston rod 910a) to be rotated, and the connection arms (51b, 51b) are eccentrically installed in different directions on the basis of the rotation axis center of the balance earth axis (51a). A rolling cylinder (14) for rotating the balance earth axis (51a) is connected between one of the ascendance adjusting rods (3a, 3a) and one of the connection arms (51b, 51b) to be extended.
