PROBLEM TO BE SOLVED: To provide a seedling transplanter capable of performing current position planting without any complicated operation before a travel vehicle body starts planting travel and capable of reliably supplying fertilizer to a seedling planted by the current position planting.SOLUTION: The seedling transplanter includes: a seedling planting part and a fertilization device on a travel vehicle body 2 an output operation member operating transmission output to the travel vehicle body 2, the seedling planting part and the fertilization device a travel transmission cut-off mechanism 104 cutting off travel transmission to the travel vehicle body 2 when output is stopped by operation with the output operation member a fertilization drive member transmitting power to the fertilization device and a control device operating the fertilization drive member if a seedling planting part 4 is in a planting work state when the output operation member is operated to increase output from an output stop state and also operating the seedling planting part 4 after having switched the travel transmission cut-off mechanism 104 into a transmission state.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2016,JPO&INPIT【課題】走行車体が植付走行を開始する前に、複雑な操作をすることなくその場植えを行えると共に、その場植えにより植え付けられた苗に確実に肥料を供給できる苗移植機を提供する。【解決手段】走行車体2に苗植付部と施肥装置を設け、走行車体2、苗植付部及び施肥装置への伝動出力を操作する出力操作部材を設け、出力操作部材を操作して出力停止させると走行車体2の走行伝動を遮断する走行伝動遮断機構104を設け、施肥装置に伝動する施肥駆動部材を設け、出力操作部材が出力停止状態から出力上昇操作されたとき、苗植付部4が植付作業状態であれば、施肥駆動部材を作動させると共に、走行伝動遮断機構104を伝動状態に切り替えてから苗植付部4を作動させる制御装置を設ける。【選択図】 図6
