A sled portion 17 is formed in the front part of the side cover member 14, and the side cover member 14 moves up and down according to the ups and downs of the ridge by sliding on the upper surface of the ridge to prevent the mud from scattering to the side of the ridge. .

In this embodiment, the mounting bracket 18 is attached to the rear side of the upper cover member 10 in the ridge forming direction.
Holding rods 19 are vertically installed on both left and right sides of 18 so that they can be adjusted up and down, a plurality of adjustment holes 20 are formed in the holding rod 19, and insertion pins 21 are inserted into the adjustment holes 20 at the upper position of the mounting bracket 18 for mounting. A rubber seat 22 is interposed between the upper surface of the bracket 18 and the insertion pin 21 to fix the holding rod 19 in position, and a fixing pin 23 is provided between the lower portion of the holding rod 19.
The rear cover member 24 is connected by means of, and a flexible cover member 26 is hung vertically from below the rear cover member 24 by means of bolts 25.

Further, the flexible cover member 26 of this embodiment is made of rubber having flexibility and is formed in a substantially V-shaped cross section as shown in FIG. 3, and is grounded to the upper surface of the ridge and one side surface of the ridge. It is formed so as to slide.

Since this embodiment has the above-described structure, when the tractor 1 travels along the ridge 5, the embankment rotor 4 lands the embankment on the ridge 5 side.
The embankment is piled up and the embankment is beaten and compacted by the reciprocating motion of the ridge striking body 6.

At this time, the embankment rotor 4 bounces off the mud with vigorous force to embed it, the upper cover member 10 prevents the muddy soil from scattering above the embankment rotor 4 and above the ridge 5, and the side cover member 14 causes the ridge 5 to rise. In accordance with the ups and downs of the upper surface of the ridge, it moves up and down to prevent the mud from scattering to the side of the ridge 5, and the rear cover member 24 and the flexible cover member 26 prevent the scattering of mud to the rear, and the flexible cover member 26 is substantially flat. Since it is formed in the shape of a letter and is in sliding contact with the upper surface and one side surface of the ridge 5, it is possible to satisfactorily prevent the scattering of mud to the rear, and thus the embankment efficiency can be improved, and a new ridge 5 that is as good as that can be obtained.
