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.
