PROBLEM TO BE SOLVED: To provide a rice transplanter in which transplant clutch is disconnected by an actuator for transplant clutch in accordance with an operation to a transplant operation member and a transplant part is moved up and down by a lifting actuator in accordance with an operation to a lifting operation member, and transplant part can be raised without requiring a clutch cutting operation by the transplant operation member and requiring only a moving up operation by the lifting operation member while breaking power transmission of transplant claws when the transplant part is required to be raised during performing planting work.SOLUTION: A rice transplanter includes: a transplant clutch 170 interposed between working system transmission paths a transmission clutch 150 interposed the working system transmission paths on an upper stream side to the transmission direction than the transplant clutch 170 and a grounding condition detecting device for detecting whether or not the transplant part is grounded. A control device operates an actuator 151 for transmission clutch to become the transmission clutch being a connected condition and a cutting condition in accordance with whether or not the transplant part is grounded.COPYRIGHT: (C)2013,JPO&INPIT【課題】植付操作部材への操作に応じて植付クラッチ用アクチュエータによって植付クラッチを断接させ且つ昇降操作部材への操作に応じて昇降アクチュエータによって植付部を昇降させる田植機において、植付作業時において前記植付部を上昇させたい際に、前記植付操作部材によるクラッチ切断操作を要すること無く、前記昇降操作部材による上昇操作のみで植付爪の動力伝達を遮断しつつ前記植付部を上昇させ得る田植機を提供する。【解決手段】作業機系伝動経路に介挿された植付クラッチ170と、前記植付クラッチ170よりも伝動方向上流側において当該作業機系伝動経路に介挿された伝動クラッチ150と、植付部が接地しているか否かを検出するための接地状態検出装置とを備え、制御装置は、前記植付部の接地及び非接地に応じて前記伝動クラッチが接続状態及び切断状態となるように伝動クラッチ用アクチュエータ151を作動させる。【選択図】図3
