<p><P>PROBLEM TO BE SOLVED: To prevent preliminary seedling frames from being switched from an overlapping state to a deployed state due to vibration. <P>SOLUTION: The seedling transplanter includes: a planting unit provided on a traveling vehicle body for planting seedlings on a farm field; a first support member secured to the traveling vehicle body; and a first preliminary seedling frame 46 connected to the first support member and having a plurality of preliminary seedling stands 47 and 48, at least one of which is movable, the preliminary seedling stands being switchable between an overlapping state in which they vertically overlap and a deployed state in which they are deployed front and back. The first preliminary seedling frame 46 includes a link member 54 turnably attached either directly or indirectly to the movable preliminary seedling stand 47, and a locking mechanism 60 for preventing the movable preliminary seedling stand 47 from moving from the overlapping state to the deployed state. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
