Now available multiple row planting transplanting machine realizes planting depth homogenising of the multiple planting row seedling on the ridge whose outside is lower than right and left to central part, but it does not relate to that the shape of the ridge is different because of forming process of ridge and quality of soil, in particular outside end angle of inclination is large in right and left direction of the ridge and height is easy to fluctuate, and that could make the planting depth of the multiple planting row seedling suitable. So that the object of the invention is relative to various shapes of the ridge and realizes planting depth homogenising of the multiple planting row seedling. In multiple row planting transplanting machine, height change mechanism is set, and puting transplant rice seedlings body inside of the right and left direction of the body as benchmark, height changes handle to change up and down height of the transplant rice seedlings outside of the right and left direction. Moreover, front-wheel and rear-wheel are set on the body, a plurality of transplant rice seedlings bodies are set in the rearer position than axle of the above rear-wheel, transplant rice seedlings bodies outside of the right and left direction of the body are set in the fronter position than transplant rice seedlings bodies inside of the right and left direction of the body.
