PROBLEM TO BE SOLVED: To provide a seedling transplanting machine which forms a wide planting interrow space on every number of rows of an integral multiple of the number of planting rows when planting seedling and forms a work passage where a worker moves when working in post processes.SOLUTION: A seedling transplanting machine 1 for planting on a plurality of rows is structured as follows: spacers 35 are respectively set between a central transmission case 32 and planting bodies 34 at a lateral center part to make a lateral space S1 between the planting bodies 34 at the lateral center part wider than lateral spaces S2 between the planting bodies 34 at parts other than the lateral center part and thereby a planting interrow space P1 at the lateral center part is wider than planting interrow spaces P2 of other parts. Planting travel in a plurality of processes is performed to execute planting work while forming a wide planting interrow space on every number of rows of an integral multiple of the number of planting rows by the seedling transplanting machine 1.COPYRIGHT: (C)2014,JPO&INPIT【課題】苗の植付作業を行う際、植付条数の整数倍の条数毎に広い幅の植付条間を形成し、後工程の作業時に作業者が移動する作業通路を形成することができる苗移植機を提供する。【解決手段】中央伝動ケース32と左右中央部分の植付体34の間に各々スペーサ35を設けることにより、左右中央部分の植付体34同士の左右間隔S1を他の部分の植付体34同士の左右間隔S2よりも広くして、左右中央部分の植付条間P1を他の部分の植付条間P2よりも広くして構成する複数条植えの苗移植機1により、複数行程の植付走行を行い、苗移植機1の植付条数の整数倍の条数毎に広い幅の植付条間を形成しながら植付作業を行う。【選択図】図2
