PROBLEM TO BE SOLVED: To enable reserve seedling stands to be easily placed in a state of their being arranged at a predetermined interval in a vertical direction and in a state of their being arranged in a row, in a sulky-type rice transplanter.SOLUTION: In a sulky-type rice transplanter, a first state and a second state are set: in the first state, three reserve seedling stands, i.e. an upper seedling stand 51, a middle seedling stand 52, and a lower seedling stand 53, are arranged at a predetermined interval in a vertical direction, and in the second state, the three reserve seedling stands 51, 52, 53 are arranged in a row. A first link member 32 is swingably supported about a rear lateral shaft axis P24 of a support frame 24, a second link member 33 is swingably supported about a front lateral shaft axis P34 of the support frame 24, and a third link member 31 is provided separately from the first and the second link members 32, 33. Thus the upper, the middle, and the lower reserve seedling stands 51, 52, 53 are freely placed in the first or the second state by swing operation of the first, the second, and the third link members 32, 33, 31.COPYRIGHT: (C)2014,JPO&INPIT【課題】乗用型田植機において、予備苗のせ台を上下方向に所定間隔を置いて配置した状態及び予備苗のせ台を一列状に配置した状態を容易に得ることができるように構成する。【解決手段】3つの予備苗のせ台51,52,53を上下方向に所定間隔を置いて配置した第1状態、上段、中段及び下段の予備苗のせ台51,52,53が一列状に配置された第2状態を設定する。支持フレーム24の後横軸芯P24周りに、第1リンク部材32を揺動自在に支持し、支持フレーム24の前横軸芯P34周りに、第2リンク部材33を揺動自在に支持して、第1及び第2リンク部材32,33とは別の第3リンク部材31を備える。第1,2,3リンク部材32,33,31を揺動操作することにより、上段、中段及び下段の予備苗のせ台51,52,53を第1及び第2状態に操作自在に構成する。【選択図】図7
