Furthermore, between the position (P1) immediately before the transplant claw (3B) divides the seedlings placed in the seedling tank (20) and the appropriate position after division (P2), the tip of the transplant claw (36) is attached to the seedling. The power transmission rattling regulating device operates to rotate in direction b (the same direction as the resistance force received when dividing the seedlings), which is opposite to the direction in which the seedlings tied to the tank (20) are divided! Since (A) is configured, transmission play can be reliably and effectively eliminated.

Next, to explain the function of the upper side, the seedling tank (20)
When the seedlings are placed on the plate and each part is rotated by the engine (lO), the passenger tractor (1) is propelled by the rotation of the front wheels (5) and rear wheels (7), and the transplant II (18) part is moved to the leveling float (22).
) φ(23) and (23) part of the load is received and towed, and the power is transmitted from the front transmission case (3) side to the input shaft in the transmission case (19) via the transmission shaft. . In this way, power is transmitted from the input shaft in the transmission case (19) through an appropriate transmission route to the drive shaft (28
) is transmitted. Then, each rotating case (28) rotates,
With this rotation, the counter planetary gears (32) (32) are planetarily rotated around the sun gear (31), and the planetary gears (33)-(33) meshing with these are rotated. Therefore, the planetary gear (33)・(3
The transplant device body (35a) is rotated via the transplant device drive shaft (30) and the mounting bracket (42) provided integrally on the rotating case (29) via the boss portion (39a). - The cam body (39) attached to the body weight is rotated with a deviation from the rotation of the transplanting tool body (35a), and for this reason, the seedlings are not extruded through the continuous tBJ member (38). The fork (37) will be moved up and down.
