The rear wheel 15 is greatly displaced outward in the lateral direction with respect to the rear wheel 15, and the wheel width of the front wheel 14 is wider than that of the conventional transplanter 2 (the wheel width of the front wheel 14 is the rear wheel 15. It ’s wider than the circle ’s ring).
The front wheel 14 on one side of the left and right side is the heel R2 on the left and right side adjacent to the heel R1 where the seedling N is planted, and the heel where the seedling N is planted among the heels R1, R4 adjacent to the heel R2. Rolling the intercostal groove 30 between R1 and different ridge R4, the front wheel 14 on the left and right other side (left side) is the heel R1 where the seedling N is planted, and the left and right other side adjacent to the ridge R1 It is comprised so that it may roll in the groove | channel 30 between ridges R3, and it is comprised so that the right-and-left front wheel 14 may straddle 2 ridges R1 and R2.

Thereby, even if the front wheel 14 on one side rides on the placement soil 31 that holds the entire multi 7, the front wheel 14 has a wide wheel range, and thus the left and right inclination of the body 1 </ b> A is smaller than that of the conventional transplanter 2.
Thereby, since rolling of the body 1A can be prevented and the seedlings N can be prevented from being planted in a meandering manner, planting accuracy can be improved.
Further, the left and right rear wheels 15 roll over the intercostal groove 30 between the heel R1 and the ridges R2 and R3 adjacent to the heel R1 across the ridge R1 where the seedling N is planted.
The rear wheel 15 may have a wider wheel width so that the left and right rear wheels 15 straddle a plurality of ridges R. However, when turning at the end of the field (headland), the machine body 1A is lifted up. The steering wheel 9 is pushed down and the steering wheel 9 is pushed down to turn while the front wheel 14 is lifted from the ground. Therefore, when turning at the end of the field, the turning radius increases if the left and right rear wheels 15 are wide. Therefore, it is difficult for the vehicle to turn.

FIG. 2 shows a second embodiment of the present invention.
In the traveling body 1 of this embodiment, the pair of left and right front wheels 14 straddle 3 畝 R1, R2, R3, and the seedling N is planted in the middle 畝 R among these 3 畝 R1, R2, R3. The configuration differs from the first embodiment in that it is configured as described above.
In this second embodiment, the left and right front wheel support shafts 18 are respectively extended outward in the left-right direction, and the left and right front wheels 14 are laterally outward with respect to the rear wheel 15 on the same side. The wheel width of the front wheel 14 is wider than that of the conventional transplanter 2.

In this second embodiment, the left and right rear wheels 15 are each a seedling R2 adjacent to the seedling R1 where the seedling N is planted, and a seedling among the seedlings R1 and R4 adjacent to the basement R2. Roll the intercostal groove 30 between the ridge R1 where the planting operation of N is performed and a different ridge R4.
In the second embodiment, when the front wheel 14 rides on the placing soil 31 that holds the entire multi 7, the left and right inclination of the airframe 1A is smaller than that of the first embodiment, so that the airframe 1A The roll prevention effect is great.
In the first embodiment, the left and right front wheel support shafts 18 may be further extended outward in the left-right direction so that the left and right front wheels 14 straddle the three flanges R. Alternatively, it may be configured to straddle 4 畝 R or more (a configuration in which a plurality of ridges R are straddled by the left and right front wheels 14 and a seedling N is planted in one ridge R of the plurality of ridges R) As long as it has been.)
