PROBLEM TO BE SOLVED: To make it possible to easily adjust between stripes of a plurality of transplanting units.SOLUTION: In the seedling transplant in which the transplanting part is elevatably coupled to the rear part of the running part and the transplanting part transplants seedlings in the agricultural field while the transplanting part is towed by the running part, the transplanting part mounts the seedling feeder for feeding seedlings on the supporting machine frame, the seedling taking unit taking out the seedlings from the seedling feeder, the transplanting means for receiving the seedlings taken out by the seedling taking unit and transplanting the same in the agricultural field are integrally assembled to the unit machine frame as the transplanting unit, the unit machine frame is detachably attached to the supporting machine frame such that the attaching position can be freely adjusted in the right and left width direction.COPYRIGHT: (C)2012,JPO&INPIT【課題】複数の移植ユニットの条間調節を楽に行うことができるようにすること。【解決手段】走行部の後方に移植部を昇降自在に連結して、走行部により移植部を牽引しながら移植部が圃場に苗を移植するようにした苗移植機において、前記移植部は、支持機枠上に苗を供給する苗供給手段を載設する一方、苗供給手段から苗を取り出す苗取手段と、苗取手段により取り出した苗を受けて圃場に植付ける植付手段を移植ユニットとしてユニット機枠に一体的に組み付けて、支持機枠にユニット機枠を左右幅方向に取付位置調節自在かつ着脱自在に取り付けた。【選択図】図9
