In other words, ridge top surface forming member 7 of the roller type, for example "150cm ² ≦ S ≦ 1225cm ^2" (preferably 150cm ² ≦ S ≦ 600cm ²⁾ satisfies the. The enclosed area S (the shaded portion in FIG. 2) is the amount of compressed soil when the ridge upper surface forming body 7 moves by the horizontal distance K in the side view. In the example shown in FIG. 2, "S" is used. = 225 cm ² ".

Further, as shown in FIG. 3, the rotation speed (rotation speed of the rotation shaft 25) V1 of the upper surface roller 31 of the ridge upper surface forming body 7 is lower than the rotation speed (rotation speed of the rotation shaft 21) V2 of the filling body 3. The range is, for example, 0.35 to 0.9 times the rotation speed V2 (preferably the range of 0.35 to 0.6 times).

When the ridge coating machine 1 is moved in the traveling direction at a relatively high moving speed by the traveling of the tractor, the embankment body 3 cultivates and heaps the soil of the rice field and the ridge while rotating at the rotation speed V2.

Behind the embankment 3 in the traveling direction, the ridge side surface forming body 6 compacts the embankment while rotating at a rotation speed V1 slower than the rotation speed V2 to form the ridge side surface, and the ridge top surface forming body 7 is The embankment is compacted to form the upper surface of the ridge while rotating at the same rotation speed V1 as the ridge side forming body 6.

At this time, the working surface c of the ridge upper surface forming body 7 compresses and compacts a desired amount of soil corresponding to high-speed work to form a strong ridge upper surface.

Then, according to the ridge coating machine 1, the surrounding area S when the ridge upper surface forming body 7 moves by the horizontal distance K between the front end a and the lower end b in the side view is 150 cm ² or more and the ridges. Since the rotation speed V1 of the top surface forming body 7 is in the range of 0.35 to 0.9 times the rotation speed V2 of the embankment body 3, the working speed of the ridge coating work should be increased as compared with the conventional one.
