The invention provides a seedling planting machine, which can plant the seedling smoothly by peeling off the mud attached on the body after planting the seedling. The seedling planting machine is provided with a running device with an engine, a front wheel and a rear wheel； a seedling planting device (4) with a seedling body (4a) for planting the seedling provided by a seedling feeding device to the field； a link mechanism (3) for driving the seedling device (4) to reciprocate at the compulsory action track； a planting transmission mechanism in a planting drive case for driving the link mechanism (3) to reciprocate； and a top and bottom drive portion for driving the link mechanism to reciprocate, which is connected with the planting transmission mechanism, wherein if the planting transmission mechanism is provided with means for pressing the seedling body (4a), a scraper (70) for removing the mud of the seedling body, a drive mechanism for driving the scraper to move in the fore-and-aft direction, and a common driving shaft of the top and bottom drive portion and the drive mechanism are projected from a planting transmission case, and the top and bottom drive portion and the drivemechanism are linkaged with each other by the driving shaft.提供藉由使附著於栽種苗之後之苗栽種體之泥剝離而能順利進行利用苗栽種體之苗之栽種之插秧機。；於設有具備引擎(5)與前輪(6)與後輪(7)之行進裝置(1)，具有將由苗供給裝置(40)供給之苗栽種於農地之苗栽種體(4a)之苗栽種裝置(4)，使該苗栽種裝置(4)以特定之作動軌跡上下動之連桿機構(3)，使該連桿機構(3)上下動之栽種傳動箱(18)內之栽種傳動機構之插秧機，將使前述連桿機構(3)上下動之上下驅動部連結於前述栽種傳動機構；於前述栽種傳動機構設置按壓於苗栽種體(4a)時去除該苗栽種體(4a)之污垢之刮板(70)、使該刮板(70)於前後方向動作之驅動機構；使於上下驅動部與驅動機構共通之驅動軸(53)從栽種傳動箱(18)突出設置，透過該驅動軸(53)互相連動上下驅動部與驅動機構。
