PROBLEM TO BE SOLVED: To prevent deviation of the front-rear balance of a machine body even when carrying out the work of planting seedlings by placing a plurality of containers storing water to be supplied when transplanting the seedlings to a field. Provided is a seedling transplanter capable of suppressing the variation in the planting depth of seedlings caused by the leaning of the machine body due to leaning. A seedling transplanter has a transmission case 15 in which means for transmitting a driving force of a drive device to a traveling device 14 from an input shaft 16 provided in a vehicle body 10, a seedling planting device 30, and water is stored. The container 95 is provided with a mounting member for mounting the container 95, and the irrigation device 60 for supplying the water in the container 95 to the field in which the seedlings are planted. The front mounting part 51 for mounting the container and the rear mounting part 52 for mounting the container at a position behind the input shaft 16 are provided, and the irrigation device 60 is mounted on the front mounting part 51. The water in the front container 95F and the water in the rear container 95R mounted on the rear mounting portion 52 are supplied. [Selection diagram] Fig. 4【課題】苗を圃場に移植する際に供給する水を貯留した容器を複数載置して苗の植付け作業を行う場合でも、機体の前後バランスに片寄りが生じにくくなり、その前後バランスの片寄りにより機体の前後傾斜が発生して苗の植付け深さが変動することを抑制できる苗移植機を提供する。【解決手段】苗移植機は、車体１０に設けた入力軸１６から駆動装置の駆動力を走行装置１４に伝動する手段が収容された伝動ケース１５と、苗の植付け装置３０と、水を貯留した容器９５を載置する載置部材と、容器９５の水を苗が植え付けられた圃場に供給する灌水装置６０とを備え、載置部材は、伝動ケースの入力軸１６よりも前方の位置に容器を載置する前方載置部５１と入力軸１６よりも後方の位置に容器を載置する後方載置部５２とを有しており、灌水装置６０は、前方載置部５１に載置される前方の容器９５Ｆの水と後方載置部５２に載置される後方の容器９５Ｒの水を使用して供給する。【選択図】図４
