The seedling clamping discs 13, 13 are clamped by the seedling clamping discs 13, 13 because they are pressed from the outside by a plurality of pressure rolls attached to the left and right guide plates 31A, 31B of the groove cutter 5, respectively. The seedling moves along the center of the guide path 31. Therefore, regardless of the thickness of the seedling, the seedling is planted perpendicularly to the groove b without coming into contact with the guide plates 31A, 31B and tilting.

On the other hand, a front guide wheel 3 provided below the front of the chassis 1
4 smoothly rolls on one side wall in a pre-formed groove a, as shown in FIG. It rolls smoothly on the other side wall. Therefore, the resistance between the guide wheels 34, 36 and the side wall in the planting groove a is extremely small, and the chassis 1 can run straight and smoothly on the planting groove a without turning, so that the transplanting position of the green onion seedlings can be adjusted. As shown in FIG. 5, it is always on one side wall side of the planting groove a.

(Effects of the invention) As described above, in the present invention, a front guide wheel that rolls on either the left or right side wall of the groove is provided below the front of the chassis, and a front guide wheel that rolls on either the left or right side wall of the groove is provided below the rear of the chassis. Since a rear guide wheel is provided that rolls on either the left or right side wall, both guide wheels can smoothly move on the side wall regardless of the soil condition in the trench. Therefore, the vehicle platform can run straight and smoothly on the planting groove without turning, and the position for transplanting green onion seedlings is always at a constant position without turning.

Since the front guide wheel and rear guide wheel are far apart, the large moment applied to the chassis due to the creation of the kerf b is supported with a small force, and the force hitting the side wall is weak, allowing the chassis to run straight without collapsing the side wall. It has the effect of causing
