FUNCTION AND EFFECT OF THE INVENTION The float 2 of the seedling planting device that slides on the soil surface at the rear part of the vehicle body makes the tracks of the wheels 1 smooth while sliding. On the soil surface leveled by the leveling part 4 of the float 2, seedling planting action by the seedling planting device 3 is performed at the position A on both sides of each of the left and right floats 6, and -4 seedlings A will be planted per 2 g. The mud pushed on the front side of the float 2 is guided by the mud drainage groove 5 located in the central portion of the left and right width, and is inserted between the seedling planting sections A at the intermediate portion between the left and right float bodies 6. It is discharged toward the rear side from the positioned open groove 7 part.

For this reason, since the mud draining groove 5 having a relatively short length is used to drain the mud at the center of the wide area between the left and right float bodies 6, the mud draining resistance is small and smooth. While removing mud, it is possible to perform accurate ground leveling over a wide area, and the amount of mud that is pushed out to the left and right is small. In addition, the ground contact surface of the float is large, the bearing capacity of the planting portion on the surface soil surface is increased, and the up / down / left / right surface soil surface followability is improved.
