2. Description of the Related Art Conventionally, a method of cultivating a field in a state where crops are harvested to a deep layer and replacing the entire cultivated layer, and planting seedlings in a field after harvesting grain stalks in a non-tilled state. Methods and planting machines that plow only the narrow width of the field and plant seedlings in the plowed part are already known.

[0003]

Among the above-mentioned known planting methods, the first method requires a great deal of labor to replace the entire cultivated layer, and is kneaded to the deep layer to eliminate voids in the soil. Moreover, after the scraping, the planting operation must be separately performed by the planting device. Further, the second method is that, in the field at the time of planting, there are crawl marks and pits of a combine at the time of harvesting, which lacks uniformity, and because there are many old plants and weeds, remarkable deep planting or shallow planting is performed. Floating seedlings and poor growth occur. Further, the third method, upright holding of plantings seedlings is difficult because there is no sticky soil tillage portion of the planting ridges. In order to solve such problems, the surface layer of the field that caused tillage shallow Dai掻by Dai掻rotor seedlings were already proposed a plant scheme for this Dai掻section min. As a drive device for the scraping rotor, an input shaft of a gear case is interlockedly linked to a scraping PTO shaft of a traveling vehicle, and an output shaft protruding to both sides from the gear case is replaced by a joint such as a spline joint. When connecting the edge of the die掻軸the take-rotor, in Dai掻work, the right and left Dai掻rotor receives a non-uniform resistance, connected by joints algebraic掻軸
In some cases, the joint was twisted, and the joint came off or was damaged, making transmission impossible. Further, since the substitute shaft is divided into at least two on the left and right sides of the gear case, the supporting means becomes complicated and the height adjustment is troublesome.
