PROBLEM TO BE SOLVED: To provide a seedling transplanter that is configured to execute an automatic engine-stop control only when a condition is satisfied in which a stop of an engine rotation does not cause any problem and configured to have a smaller number of operation steps for restarting the engine.SOLUTION: A seedling transplanter includes: an engine 1 in a vehicle body 3 a lift link mechanism 4 disposed behind the vehicle body 3 in a movable manner in an upward and downward direction a seedling planting portion 5 configured to plant seedlings in a field and disposed on the lift link mechanism 4 a descent detection sensor 7 configured to detect a descent of the seedling planting portion 5 a planting operation lever 6 configured to operate lifting of the seedling planting portion 5 and planting and a lever potentiometer 8 configured to detect an operation position of the planting operation lever 6. When the decent detection sensor 7 detects that the seedling planting portion 5 is lowered to a predetermined height while the lever potentiometer 8 detects "planting low", the engine 1 is stopped after a predetermined period of time.COPYRIGHT: (C)2014,JPO&INPIT【課題】エンジン回転が停止しても問題のない条件が揃ったときのみエンジンの自動停止制御が行われると共に、再始動させる際の操作工数が少ない苗移植機を提供することを目的とする。【解決手段】走行車体3にエンジン1を設け、走行車体3の後部に昇降リンク機構4を昇降自在に設け、昇降リンク機構4に圃場に苗を植え付ける苗植付部5を設け、苗植付部5の下降を検知する下降検知センサ7を設け、苗植付部5の昇降及び植付を操作する植付操作レバー6を設け、植付操作レバー6の操作位置を検知するレバーポテンショメータ8を設け、レバーポテンショメータ8が「植付下」を検知しているとき、苗植付部5が所定高さまで下降したことを下降検知センサ7が検知すると、所定時間後にエンジン1を停止させる構成とする。【選択図】図6
