As a result, the tilling section 12 in the center of the tilling device 8
As a result, the tilling and crushing work is performed as opening work, and at the same time, the discs 53 of the plows 13 on both the left and right sides of the tilling section 12 cut into the soil as they rotate.
The soil is cut up, guided according to the curve of the inside surface, turned over, and thrown diagonally inward to the rear as dirt, ensuring that straw, weeds, etc. in the field are removed by turning over the gravel. They embed themselves in the soil and accelerate their corrosion.

By the way, in the above case, the tilling claws 49 are arranged symmetrically about the lateral center position in the tilling section 12, and the tilling claws 49 arranged on each left and right side of the tilling section 12 are directed toward the left and right sides, respectively. Therefore, the tilling claws 49 on the left and right sides of the tilling section 12 can blow the tilled soil symmetrically forward and diagonally outward, so that the tilling section 12 has a good opening effect, and the disc 53 of the plow 13 can spread the soil. In addition to being able to perform the reversing and throwing work well, the tilling section 1
The plowing marks 65 of the plowing part 12 do not bulge up or fall more than the rubble soil 66 of No. 2, and the plowing marks 65 of the plowing part 12 become good.

In addition, since the tilling section 12 is rotationally driven in the upcut direction, even if there is straw on the ground of the field, the tilling claws 49 will not come into contact with the straw through the tilled soil mass when coming out of the soil. Since straw and the like are blown away together with the tilled soil clods, straw and the like are less likely to get entangled with the tilling claws 49.

<Effects of the Invention> As described in detail above, according to the present invention, each disc shaft is moved backward and diagonally outward from the right and left ends of the tilling shaft via an interlocking mechanism that interlocks the tilling shaft and the disc shaft. Since it extends to the side, the length of the entire tilling device in the front and back direction can be made shorter than before, and therefore, the weight balance between the tractor and the tilling device can be made good, allowing the tilling device to perform plowing work well. At the same time, the drive mechanism for the tilling section and the plow can also be simplified.

In particular, according to the first invention, since the drive mechanism is a mechanism that rotates the tilling part in the up-cutting direction, even if there is straw or the like on the ground of the field, the tilling claws can Since it hits straw etc. through the tilled soil clod and blows the straw etc. off with the tilled soil clod, it is difficult for straw etc. to get entangled in the tilling claws.

Further, according to the second invention, since the interlocking mechanism is a mechanism that allows the plow to rotate around the interlocking mechanism in plan view, each disc shaft can be connected from each side end of the tilling shaft via the interlocking mechanism. Even though the plow extends, the plow's gearing angle can be adjusted by simply adding a gearing angle adjustment device of the plow as in the embodiment.

Furthermore, according to the third invention, in addition to the configuration of the second invention, the tilling shaft and the disc shaft are interlocked by the interlocking mechanism so that the tilling shaft rotates at a higher speed than the disc shaft. Even though the disk shaft extends from each side end of the tilling shaft, the tilling section and the plow can be rotated at appropriate rotational speeds.
