PROBLEM TO BE SOLVED: To provide a seedling transplanting machine that can prevent the breakage of a planting rotary and a planting clutch due to an overload, even if the planting clutch is not cut by any chance in the reverse travel of a machine body.SOLUTION: A seedling transplanting machine is provided with a transmission case 12 in which a traveling transmission system A and a seedling planting transmission system B for transmitting the power from an engine 20 to running wheels 10 and 11 and a seedling planting unit 4, respectively, are included inside, respectively. A planting transmission shaft 66 for transmitting a driving force from the seedling planting transmission system B in the transmission case 12 to a seedling loading member 51 and a seedling planter 52 of the seedling planting unit 4 is provided, and a forward-and-reverse rotation driving mechanism 19 for reversing the transmission rotation of the planting transmission shaft 66 even when a traveling lever 93 is reversely operated is provided in the seedling planting transmission system B.COPYRIGHT: (C)2015,JPO&INPIT【課題】機体の後進時に万一植付クラッチが切れなくても、過負荷による植付ロータリや植付クラッチの破損を防止することができる苗移植機を提供すること。【解決手段】エンジン20からの動力を走行用車輪10、11と苗植付部4にそれぞれ伝達する走行伝動系Aと苗植付伝動系Bをそれぞれ内部に備えたミッションケース12を設け、該ミッションケース12にある苗植付伝動系Bからの駆動力を苗植付部4の苗載置部材51と苗植付装置52に駆動力を伝動する植付伝動軸66を走行レバー93が後進操作される場合にも植付伝動軸66の伝動回転を逆転させる正逆転伝動機構19を前記苗植付伝動系B内に設ける。【選択図】図3
