Since the first embodiment of the present invention has the above-mentioned configuration, when the traveling machine body 1 travels along the ridge W and the power take-off shaft 6 is rotated, the rotary rotor as the embankment body 5 of the embankment mechanism 4 is rotated. The field mud at the edge of the ridge is continuously bounced and raised on the old ridge, and the cover member 10 and the side cover member 11 prevent the muddy soil from scattering above and above the embankment body 5 and Outer scattering is prevented and it falls by its own weight. On the other hand, the ridge adjusting mechanism 12 is driven.

By rotating and contacting to adjust the tightening pressure, the upper surface W ₁ and the one side surface W ₂ of the ridge W can be reliably pressed, and at this time, the lower drive shaft 23 and the upper adjuster 23 for supporting and rotating the lower ridge roll body 13 are rotated. Since the upper drive shaft 25 that supports and rotates the ridge roll body 14 is configured to rotate at mutually different rotational speeds, each of the upper ridge roll body 14 and the lower ridge roll body 13 has different shapes. It is possible to suppress variations in the rotational clamping pressure action caused by the difference in peripheral speed on the peripheral surface of the ridge W, and to rotate the ridge W at a speed suitable for each of the upper surface W ₁ and the one side surface W ₂ of the ridge W. To obtain good rotational clamping pressure Can, it is possible to perform a good Seiaze work.

In this case, since the rotation mechanism 15 is provided with the speed change transmission mechanism 27 for rotating the upper ridge control roll body 14 and the lower ridge control roll body 13 at mutually different rotation speeds, they are rotated at mutually different rotation speeds. The structure can be simplified, and in this case, the lower ridge forming roll body 13 has a substantially conical outer peripheral surface 13a capable of arranging the one side surface W ₂ of the ridge W into a laterally rotating roll shape.

By rotating at different rotational speeds so that ₁ and ₁ have substantially the same speed, it is possible to suppress the variation in the peripheral speeds of the ridges W, and the upper surface W _{1 of the} ridge W and the one side surface W ₂ are respectively correspondingly suppressed. Therefore, it is possible to rotate at a rotation speed that is substantially matched, and it is possible to obtain a good rotational clamping pressure action.
