PROBLEM TO BE SOLVED: To provide a transplanter in which the ridges are appropriately leveled to improve the planting accuracy of seedlings and the number of parts is reduced. [Solution] A seedling transplanter comprising a traveling vehicle 1 equipped with a cockpit 20 and capable of traveling, and a seedling transplanting device 3 arranged at a rear portion of the traveling vehicle 1 and capable of transplanting seedlings into a field, The seedling transplanting device 3 is provided so that the height position can be changed up and down by expanding and contracting the hydraulic cylinder of the lifting link device 2, and can be vertically rotated within a predetermined range without depending on the expansion and contraction of the hydraulic cylinder of the lifting link device 2. And a pressure reducing portion A whose pressure can be suppressed by the grounding roller 33 grounded on the ridge surface, the pressure reducing portion A being provided so that the vertical position of the grounding roller 33 can be adjusted. With the seedling transplanter, the ridges are properly leveled to improve planting accuracy of seedlings, and the number of parts is reduced [selection diagram].【課題】畝面が適切に均して苗の植付精度を向上するとともに、部品点数の削減が図られる移植機を提供する。【解決手段】 操縦席２０を備えて走行可能な走行車両１と、前記走行車両１の後部に配設され、圃場に苗を移植可能な苗移植装置３とを備える苗移植機であって、 苗移植装置３は、昇降リンク装置２の油圧シリンダの伸縮によって高さ位置を上下に変更可能に設けられ、かつ、前記昇降リンク装置２の油圧シリンダの伸縮によらず所定範囲で上下回動可能に構成されるとともに、畝面に接地する接地ローラ３３によって畝面が鎮圧可能な鎮圧部Ａを備え、前記鎮圧部Ａは、前記接地ローラ３３の上下高さ位置を調節可能に設けられたことを特徴とする苗移植機によって、畝面が適切に均して苗の植付精度を向上するとともに、部品点数の削減が図られる【選択図】 図１
