PROBLEM TO BE SOLVED: To provide a seedling transplanter equipped with a turning-interlocking mechanism which can perform lowering of a seedling-planting part and initiation of transplanting in suitable timing in turning travelling at a high speed, and automatically releasing the turning-interlocking mechanism, when a turning travelling unable to move to a seedling-planting initiation position is carried out.SOLUTION: A seedling-planting part 4 is liftably installed to the rear of a travelling vehicle body 2, a turning-interlocking mechanism for lowering the seedling-planting part 4 at a predetermined position after turning travelling is implemented, a steering member 34 is rotatably is provided, a steering angle-detecting member 74 for detecting a rotation angle of the steering member 34 is installed, a travelling-operating member 111 for operating to change a travelling speed is installed, an amount of operation-detecting member 112 for detecting the amount of operation of the travelling-operating member 111 is installed, and when the steering angle-detecting member 74 detects the initiation angle of the turning travelling and a control device 200 determines that the turning-travelling speed is in a high speed, the predetermined position for lowering the seedling-planting part 4 is changed to the side of finishing of the turning traveling by depending on the detection of the amount of operation-detecting member 112.COPYRIGHT: (C)2014,JPO&INPIT【課題】高速で旋回走行する際に、適切なタイミングで苗植付部の下降や苗の植付開始を行える旋回連動機構を備え、苗の植付開始位置に移動し得ない旋回走行を行うと自動的に旋回連動機構が解除される苗移植機を提供する。【解決手段】走行車体2の後部に苗植付部4を昇降自在に設け、旋回走行後に所定の位置で苗植付部4を下降させる旋回連動機構を設け、操舵部材34を回動自在に設け、操舵部材34の回動角度を検知する操舵角検知部材74を設け、走行速度を変速操作する走行操作部材111を設け、走行操作部材111の操作量を検知する操作量検知部材112を設け、操舵角検知部材74が旋回走行の開始角度を検知したとき、操作量検知部材112の検知に基づいて、制御装置200は旋回走行速度が高速であると判断すると、苗植付部4を下降させる所定の位置を旋回走行の終了側に変更する構成とする。【選択図】図17
