However, in the case where the conventional one-row outermost end portion seedling mounting table is folded forward,
The lateral width of the seedling mounting table is wider than the vehicle width of the running vehicle body, and it was necessary to further reduce the width. For this purpose, a technique has been proposed to shorten the left and right widths by folding a plurality of seedling stands on the left and right sides of the multi-row seedling stand, but a fertilizer applicator and a rear wheel are provided in front of the seedling stand. It was arranged so that it could not fold forward a plurality of seedling mounting stands on both the left and right sides. In addition, the side bumper that turns the end part to narrow the left and right width is restricted by inserting a lock pin, the position of the side bumper is fixed by inserting a snap pin, and the side bumper end In order to rotate, it is necessary to remove two pins, and these pins are located in the lower part of the front of the seedling table where it is difficult to operate, and it is difficult to remove and insert these pins. Was. Furthermore, in the configuration in which the pin can be pulled out, there is a possibility that the pin may fall off due to vibration during work and be lost.

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. That is, in a riding type rice transplanter in which a planting section for planting a plurality of rows is arranged at a rear portion of a traveling vehicle and a fertilizing section is arranged in front of a seedling mounting table of the planting section, the seedling mounting table is located at the center of the machine body. Divide the fixed-side seedling platform of the multiple rows and the multiple rows at the left and right ends into divided seedling platforms, and connect the rear surface of the fixed-side seedling platform and the rear surface of the divided seedling platform with a folding mechanism to interfere with fertilizing hoses and wheels. Instead, the divided seedling mounting table is folded over the fixed seedling mounting table. In addition, there is a seedling mounting device that folds a plurality of strips at both left and right ends of the seedling mounting table toward the center of the machine using a folding mechanism, protrudes a side bumper from the side of the planting part side, and bends a middle part of the side bumper. In a rice transplanter capable of pivoting as much as possible and narrowing the lateral width of the machine body, the side bumper is divided into a fixed-side base pipe and a turning-side turning pipe, and a stay of the turning pipe is pivotally connected to the base pipe. An arc-shaped guide groove and a stop hole having a diameter larger than the groove width are bored on the stay, and a stepped guide pin slidably and loosely fitted into the base pipe engages the stop hole. When the guide pin is slid and the stepped portion of the guide pin is positioned in the stop hole, the lock is released and the rotary pipe is rotated.
