PROBLEM TO BE SOLVED: To solve the problem that the presence of a seedling transplanting device at a rear side at an elevated position on traveling over ridges, etc., causes the posture of traveling over the ridges to become unstable since the position of its center of gravity is high and the front end part of a vehicle body is elevated. SOLUTION: This seedling transplanter obtained by linking the seedling transplanting device 8 at the rear side of a traveling vehicle body 5 of riding type by a lift cylinder 6 through a lift link 7 for lifting up and down, while descending the seedling transplanting device 8 by the above lift cylinder 6 and sliding a float 9 at a bottom part by contacting it with ground, separately inserting/planting the seedlings delivered from a seedling tank 11 on a level soil surface by a transplanting device 10 and also installing a grip handle 12 for operating the traveling vehicle body 5 at the front end part of the traveling vehicle body 5 is constituted as descending the seedling transplanting device 8 to a proper position by laying down the above grip handle 12 for operation.
