PROBLEM TO BE SOLVED: To provide a rice transplanter in which the drive in a planting part can be stopped without accompanying the rise of the planting part, and which attempts the improvement of the workability of a planting operation that plants seedlings to a field surface.SOLUTION: The rice transplanter includes: a lifting cylinder 43 that switches lifting of a planting part 3 a clutch motor 34 that switches the ON/OFF of a planting clutch 33 a float ground detector 21 that detects the ground of a center float 38 provided at the lower part of the planting part 3 a lever position sensor 62 that detects the operation of a cross lever 61 and a controller 46 that controls the up and down of the planting part 3 and the ON/OFF of the planting clutch 33, wherein the cross lever 61 makes the center a neutral position and includes a center return type switch that can operates in two directions at least, and the controller 46 makes the lifting cylinder 43 not operate, but makes the clutch motor 34 operate, and makes the planting clutch 33 in an OFF state if the cross lever 61 is performed with one raising operation, when the ground of the center float 39 is detected, and the planting clutch 33 is in a turning on condition.COPYRIGHT: (C)2013,JPO&INPIT【課題】植付部の上昇をともなうことなく植付部の駆動を停止させることができ、圃場面に苗を植え付ける植付作業の作業性の向上を図った田植機を提供する。【解決手段】植付部3の昇降を切り替える昇降シリンダ43と、植付クラッチ33の入切を切り替えるクラッチモータ34と、植付部3の下部に設けたセンターフロート38の接地を検出するフロート接地検出手段21と、クロスレバー61の操作を検出するレバー位置センサー62と、植付部3の昇降と植付クラッチ33の入切を制御するコントローラ46とを備え、クロスレバー61は中央を中立位置とし、少なくとも2方向に操作可能な中央復帰型スイッチで構成し、コントローラ46はセンターフロート39の接地が検出され、且つ植付クラッチ33がON状態のとき、クロスレバー61が1回上昇操作されると昇降シリンダ43を作動させず、クラッチモータ34を作動させて植付クラッチ33をOFF状態にする。【選択図】図3
