The operator can first get on the auxiliary step 47s and get on the upper step table 47, and can easily move up and down. Ancillary operations such as replenishing the application agent to the two hoppers 8 and 8 on the step base 47 are performed. Therefore, even if the two hoppers 8 and 8 are at a high position, the operation can be easily performed.

  The operation of the above example will be described. When the tractor body is moved forward while driving the tilling rotary 6 and the feeding devices 9 and 9, etc., the soil is tilled, and the succeeding cage forming machines 7, 7,.畝 is molded. At the same time, the feeding agent in the two hoppers 8 and 8 is fed into the four strips by receiving the feeding action of the feeding devices 9 and 9 and sprayed to the field through the guide chutes. It is sprayed corresponding to each ridge formed. The spraying position is performed on the front side of the tilling rotary 6, and the sprayed application agent is plowed and stirred together with the soil. For each tillage unit, during soil cultivation with the tilling claws 23, 23, the application agent is also agitated between the opposing disks 25, 25 and distributed between the disks 25, 25. In the groove formed between the adjacent ribs, a roller 41, 41.

  At this time, the rollers 41, 41... Move while rolling in contact with the ground, and press the bottom B of the groove formed between the lower side of the formed heel and the left and right ridges, and simultaneously press the lower ends of the left and right slopes of the heel. Therefore, the pressure at the bottom of the groove B can be reliably reduced, and the pressure at the lower end of the side slope S can be reduced, and the drainage at the groove bottom B can be improved.

  In the above-described embodiment, the application agent is sprayed together with the eaves, but the application agent spray position is locally spread between the discs 25 and 25 and does not extend over the entire area of the formed straw. And can contribute to the reduction of the application agent.

  Further, as described above, the scissors try to interpose the application agent between the discs 25 and 25 as described above, but in a scissor shape while pressing the left and right slopes S of the scissors with the succeeding scissors 7, 7. Therefore, even if the soil is stirred by the disk 25 and the tilling nail 23 and the softening is promoted, the application agent is distributed in a predetermined range without invading the outside of the disk 25, and not only the groove bottom B of the roller 41. Since the pressure at the lower end of the inclined surface S can be reduced, the collapse of the soil near the inclined surface S can be prevented, and the leaching of the application agent can be further prevented.

  Furthermore, since the rollers 41 are provided on the left and right as the number of ridges plus one as the five specifications arranged on the left and right sides on the outermost side, the tilling rotary 6 and the ridge forming device 7 can be stably supported. it can.

  Since the tilling claw 15 of the present embodiment has a so-called side drive configuration, it is easy to mount and replace the tillage unit configured on the long boss body (tubular member) 26 with respect to the center drive configuration.
