The planting unit 8 of the present embodiment has a four-row planting specification capable of planting four seedlings at the same time. The seedling stage 9 on which four mat mat seedlings can be placed, It comprises a four-row planting mechanism 10 for scraping seedlings from the lower end and planting them in a farm field, a float 11 sliding on a rice field, and the like. In the seedling mounting table 9 of the present embodiment, the mat seedling mounting surface is inclined in a front-rear and lower-lower state, and the front end side extends to the vicinity of the seat 2. Accordingly, the operator can replenish the mat seedlings to the seedling mounting stand 9 even when the operator is sitting on the seat 2.

  In this embodiment, the fertilizer tank 12 is arrange | positioned at the left side of the seat 2, and the liquid or granular fertilizer stored by this fertilizer tank 12 is applied to a farm field simultaneously with planting. In this way, the operator can supply fertilizer to the fertilizer tank 12 and check the remaining amount of fertilizer even when the operator is sitting on the seat 2. The fertilizer tank 12 is supported by a tank bracket 13 provided on the side portion of the traveling machine body 1.

  Further, on the right side of the traveling machine body 1, a seedling transfer device 15 for supplying the spare seedling 14 from the front of the machine body to the machine body is extended in the front-rear direction. The spare seedlings 14 are supplied in a state of being stored in the seedling box 16, and are usually crazed from the seedling box 16 using the scraper 17 and replenished to the seedling mounting base 9. The seedling transfer device 15 of the present embodiment includes a left and right outer frame 18 that are arranged in parallel at a predetermined interval, and a plurality of rolling rollers 19 that are rotatably laid between the left and right outer frames 18 at a predetermined interval.
