The seedling plant 2 is configured as follows. A mounting frame 30 is removably mounted behind the vertical frame 27, and a seedling case 31 is mounted on a lower end of the vertical frame 27 so as to be swingable right and left by a rolling shaft 32. A pair of sleeves 33 protrude left and right from the seedling plant case 31 (FIG. 2), and three seedling plant frames 34 extend from each. A horizontally long seedling receiving plate 35 having an L-shaped cross section is fixed to the horizontal seedling frame 34. A pair of columns 36 extend upward from the front portions of the right and left seedling planting frames 34, and a slider 37 is attached to a tip thereof. The seedling mounting table 38 inclined forward and upward is slidably supported left and right by a slider 37 and a seedling receiving plate 35, and is reciprocally driven left and right by the rotational power of the engine 7. The rotational power of the engine 7 is taken out from the right side of the main gear box 6 by a first PTO shaft (not shown), reaches a right input shaft 40 of the rolling shaft 32 by a propeller shaft 39 (FIG. 2), and is seeded. The reciprocating motion is changed by the lead cam in the case 31 and transmitted to the seedling mounting table 38 by the laterally moving rod 41. Six mat seedlings are placed side by side on the seedling mounting table 38, and the lower ends of the mats protrude above the seedling receiving plate 35 and move left and right.

Rotating cases 42 are mounted on both sides of the rear end of each seedling frame 34, and the rotating power in the seedling case 31 reaches through the seedling frame 34 and rotates counterclockwise around the central horizontal axis. It is rotating. A pair of implanted rods 43 are mounted on the respective rotating cases 42 at symmetrical positions, and the planetary gears therein rotate while maintaining the same posture during the above-described rotation. The seedlings of one strain are cut off from the end of the mat seedling by passing alternately through the opening of the seedling, and transplanted to the ground at the lower end. Therefore, when these pass, six rows of seedlings are formed on the ground surface.
[0010]
Three floats 44 are mounted beneath each seedling frame 34 to slide on the ground. The front end of each float 44 projects laterally, and the studs 43 implant the seedlings after each projecting portion 44a.
As shown in FIG. 2, a lug 45 for preventing slippage is provided on the surface of each of the crawler tracks 16L and 16R. The lugs 45 in each of the crawler tracks 16L and 16R are arranged in two rows on the left and right with the central part 45a left. A second seedling row from the outside is formed after the central part 45a without the lugs 45. It is set up so that the strip will come later. That is, if the seedlings are transplanted after the rugs 45 have passed, the seedlings to be transplanted into the recesses formed by the rugs 45 become shallowly planted, and there are other problems such as survival and the like. If the width of the crawler belt is narrower than that between the strips and the crawler belt is disposed in front of the crawler belt, the area of the crawler belt is reduced, the contact pressure is reduced, and the seedling transplanter may sink. According to the above configuration, these problems are solved.
