〔Effect of the invention〕

According to the invention, each disc of the disc cultivating bodies on both sides and the inner end portion g of the disc cultivating bodies on both sides! The pair of disks in front of A are formed by dividing them into approximately fan shapes. By arranging and fixing a plurality of curved disk plates in a circular shape, each disk can be easily formed into a desired shape. In case of partial damage to each disk, it is only necessary to replace that part without replacing the entire disk, which is economical. In addition, each disc plate in the pair of discs has a cut groove in the rear part in the rotation direction, and the plate-shaped part inside the cut groove protrudes inward, so that the raw liver to be plowed can be thrown outward to a large extent. The soil can be reliably inverted and crushed as a small washing body without being crushed, and the rotating shafts of the disc tillers on both sides of the rear are not pushed up by the inverted crushed soil. Plowing can be carried out reliably and stably, and each disk plate of the disc plowing body has a cut groove at the rear in the rotational direction, and the plate-shaped portion outside the cut groove protrudes inward. It is possible to reliably invert the earthen embankment by pushing the upper part of the raised earthen embankment in the reversal direction. Therefore, the plowing reversal work is extremely preferable due to the 80% disc at the front part and the plowing discs at both rear parts. It is something that can be done.
