ではなかった。(Problems to be Solved by the Invention) In the prior art, the seedling holding rod, which is provided opposite the seedling feeder and has a claw portion that bites into a part of the mat portion of the seedling mat, does not hold the seedlings on the seedling tray. The seedling mat is directly pressed against the surface, and depending on the thickness of the seedling mat part (bed part) or the quality of the bed part, the position of the seedling holding rod is adjusted frequently to increase the seedling holding force. If adjustments were not made, there were problems in that the seedlings would be damaged or the seedlings could not be fed properly, so they were not practical.

場に植付けて行く。Next, to explain the function of the upper side, the seedling floating prevention body 3
0 is in the operating state shown by the solid line in FIG.
When seedlings are placed on the seedlings 7 and each part is rotated by the engine 5, the riding vehicle body 3 is propelled by the rotation of the front wheels 12, 12 and rear wheels 14, 14, and the seedling planting machine 4 moves to the soil leveling float 24,
At 25°25, part of the load is received and towed, and the power is transmitted via the transmission shaft to the front transmission case 10.
The power is transmitted from the side to the input shaft inside the transmission case 21. Then, the seedling platform 22 moves left and right along the seedling receiving frame 28 to supply seedlings one after another to the seedling dividing openings 29..., and the transplanting device 23...
The seedlings are successively divided into individual seedlings through the seedling dividing opening 29 and planted on the field leveled by the leveling floats 24 and 25.

。そこで、作業者は機体を停止し、予備苗載台７，７よ
り苗の少なくなった苗載面面２２ａ上に苗を供給する。If the rear end of the seedlings on any of the seedling mounting surfaces 22a of the seedling mounting table 22 becomes smaller than the number of seedling detection devices 36, the seedling detection device 36
detects a decrease in seedlings and lights up a decrease in seedlings alarm lamp 37. Then, the operator stops the machine and feeds the seedlings onto the seedling loading surface 22a, where there are fewer seedlings than the preliminary seedling loading tables 7, 7.
そして、予備苗載台７，７上にも苗がなくなれば１機体

苗の植付は及び苗送りが行なわれるものである。In particular, since the holding rod 38a of the seedling holding body 38 is provided at the center in the left-right direction of the seedling feeding belt 35, the seedling feeding belt 35 will bend when there is a slight change in the thickness or quality of the seedling bed. It can be absorbed by the seedling presser 38 frequently.
There is no need to adjust the height of the seedlings, and the seedlings can be planted and transported in a practical and convenient manner.
