[0019] In this case, because they form the outer circumferential surface 13a can be fitted in the ridge upper face W ₁ to annular突鍔13b of the upper rotating body portion 13 of the Seiazetai 12, the deflection side of Seiazetai 12 It is possible to perform good ridge work.

Further pressure in this case, tightening the base W ₃ of ridges W by one inclined surface W base Seiaze rotating body 36 formed on the conical roll has a substantially conical outer circumferential surface 36a that fits the _second ridge W because they constitute so, it is possible to tighten the rib base portion W ₃ firmly, and the infested of infested protrusion 36c receives Seiaze reaction force, it is possible to prevent the deflection side of Seiazetai 12 Therefore, it is possible to perform good ridge work.

The present invention is not limited to the above-described embodiment. For example, as the embankment mechanism 4, a rotary rotor having a rotation axis in a direction intersecting with the ridge formation direction can be adopted. Further, in the above-described embodiment, the single ridge 12 is provided. However, a ridge having the same structure as that of the ridge 12 may be arranged at a position rearward in the traveling direction of the ridge 12. The f-shaped plate-shaped ridge body may be arranged so as to be capable of ridge hitting by a ridge hitting mechanism, and the structure of hitting the ridge using a hydraulic mechanism may be employed as the structure of the ridge hitting mechanism.

In the above embodiment, the ridge 12 and the shaving rotor 32 are rotated by the hydraulic motor. However, they may be rotated from the main shaft 7 of the tractor 1 via a mechanical transmission mechanism. Alternatively, a structure in which the rotating rotor 5 is rotated by a hydraulic motor may be adopted.

[0023]

As described above, according to the first aspect of the present invention, when the tractor travels along the old ridge, the embankment mechanism raises the field mud on the ridge on the old ridge, and the cover member Prevents the splashing of mud, and the splashed mud is prevented from splashing outward and falls by its own weight, while the soil raised on the old ridge is reciprocated by the ridge and ridge mechanism of the ridge. The ridge work is performed by being beaten by the operation, and at this time, the ridge body is formed into a rotating roll shape capable of tapping the upper surface of the ridge and one slope of the ridge, and is driven by the power source of the tractor. Since the ridge body is provided with a ridge hitting mechanism that makes the ridge hit the ridge, and a rotation mechanism that forcibly rotates the ridge ridge with the power source of the tractor is provided. Rolling progresses, and smooth ridges Finished state of the ridge surface it is ridge tapping proceeds even turned into good, it can be performed better Seiaze work.

According to the second aspect of the present invention, the upper surface of the old ridge is shaved by the shaving mechanism, so that the embankment is filled on the shaved ridge. The bondability between the old ridge and the embankment can be improved, and a stronger ridge can be obtained accordingly.
