PROBLEM TO BE SOLVED: To provide a seedling-planting implement having a constitution of a narrow machine width and a good maneuverability, since conventional seedling-planting implements are installed with two seedling-feeding devices at right and left, the right and left width of the machine body becomes wider and the controlling operability in moving the machine body becomes poor.SOLUTION: The constitution of the seedling-planting implement is provided by installing the seedling-feeding device 4 made as capable of transferring a seedling-housing body 55a from the front part of the machine body to a rear side, long in the front to rear direction, arranging a seedling-planting body 25 for planting a pot seedling N received from the seedling-housing body 55a at the rear part of the seedling-feeding device 4 and arranging seats for operators 70L. 70R at the side of the seedling-feeding device 4.COPYRIGHT: (C)2013,JPO&INPIT【課題】従来の苗植付作業機は、左右に2つの苗供給装置設けているために、機体の左右幅が広くなって、機体の移動時における操縦操作性が悪くなる。このために、本発明では、苗植付作業機を機体幅の狭い操縦性の良い構成にすることを課題とする。【解決手段】苗収容体55aを機体の前部から後方へ移動するようにした苗供給装置4を機体の前後方向に長く配置して設け、この苗供給装置4の後部に苗収容体55aから受け取った鉢苗Nを圃場に植え付ける苗植付け体25を配置し、前記苗供給装置4の側部に作業者用座席70L,70Rを配置した苗植付作業機の構成とする。【選択図】図2
