PROBLEM TO BE SOLVED: To solve a problem of a conventional seedling transplanter wherein complicated and accurate operation requiring significant time and skill is required because it is necessary for an operator to perform such operation as turning of the seedling transplanter by immediately stopping travelling of the transplanter to stop the planting operation of a planting device and largely transferring a seedling tank in a target direction when a seedling loading table is transferred to an opposite side from a side by a ridge, and to operate the seedling transplanter for planting after returning the seedling tank temporarily transferred to a lateral end to a position where seedling planting is stopped before the transfer.SOLUTION: The lateral feeding rotational frequency of a sliding shaft 1 when the seedling tank 2 is transferred to the lateral end while the power transmission of the planting device 3 is stopped is detected by a tank feed sensor 6. When the seedling planting is started after the seedling tank 2 is transferred to the lateral end, the sliding shaft 1 is rotated with the transmitted power based on the lateral feeding rotational frequency detected by the tank feed sensor 6, and the seedling tank 2 is transferred and returned to the last position where the seedling planting is stopped.COPYRIGHT: (C)2012,JPO&INPIT【課題】苗載せ台を畦際側とは反対側へ移動させるときは、苗植機の走行を直ちに停止して、植付装置の植付操作を停止して、苗タンクを目的の方向へ大きく移動させて、苗移植機の旋回操作等を行わせる。又、この一旦横端へ移動させていた苗タンクを移動前の苗植付停止位置に戻してから、苗移植機の植付動作を行わせる必要があり、煩雑で正確な操作を要し、相当の時間と熟練を要する。【解決手段】植付装置3の伝動を停止した状態で苗タンク2を横端へ移動させるときの、摺動軸1の横送回転数をタンク送りセンサ6で検出し、この苗タンク2が横端に移動した後に前記苗植作用を開始するときは、前記タンク送りセンサ6が検出した横送回転数に基づいて摺動軸1を伝動回転して、前回苗植停止位置に苗タンク2を移動復帰する構成とする。【選択図】 図4
