い。When the remaining seedlings on the seedling placing table 12 become low, the machine is stopped and the pedal 27 is depressed to rotate the preliminary seedling placing table 24 to a position rotated by 90 degrees from the position shown by the solid line in FIG. Then, the operator scoops the seedlings from the seedling raising box on the preliminary seedling placing table 24 with the seedling scooping plate 26 and supplies them to the seedling placing table 12. When the spare seedling placing table 24 is rotated rearward in this way, the spare seedling placing table 24 of the left and right spare seedling placing portions 18 and 18 is rotated.
The workability is very good because the distance between the seedling mounting table 12 and the seedling mounting table 12 becomes short.

The preliminary seedling placing table 24 is returned to the position shown by the solid line in FIG. 1, and the seedlings are supplied to the preliminary seedling placing table 24 from the ridges. When the rice planting work is completed and the machine is to be housed in a barn or the like, the spare seedling stand 24 is set to a position housed inside the body shown by phantom lines in FIG. 1, and the rotating arm 34 is rotated to the rear of the body. If you move it to the storage position, the storage space of the machine will be small.
