The rotation axis of the upper rotating ridge is arranged in a downward direction at a predetermined angle from above the lower rotating ridge toward the upper surface of the ridge, and the upper rotating ridge is provided with a conical cylinder having an outer peripheral surface formed into a conical surface. The rotation axis is from the side of one side of the ridge to the large diameter portion of the upper rotation ridge arranged in the downward direction at a predetermined angle from above the lower rotation ridge toward the upper surface of the ridge. A rotating disk member that has a shape along the outer peripheral portion of the lower rotating ridge body arranged in the upward direction at a predetermined angle diagonally upward toward the ridge and has one side surface of the ridge can be replaced and replaced . A ridge adjusting machine characterized in that a height adjusting mechanism for moving the upper rotating ridge body up and down in a direction along the outer peripheral portion of the lower rotating ridge body is provided. A machine frame is connected to the traveling machine by a connecting mechanism, a filling mechanism for raising soil on the old ridges is provided on the machine frame, and a ridge adjusting mechanism capable of tightening and adjusting the filling is provided at a position rearward in the traveling direction of the filling mechanism. The ridge adjusting mechanism consists of a lower rotating ridge body capable of arranging one side surface of the ridge and an upper rotating ridge body capable of arranging the upper surface of the ridge, and the rotation axis of the lower rotating ridge body is one of the above ridges. Arranged in an upward direction at a predetermined angle diagonally upward from the side of the side surface to the ridge side, the lower rotating ridge is provided with a drum-shaped rotating frame, and a plurality of compressions are applied to the outer periphery of the rotating frame. Along with forming a portion, the bases of a plurality of compression plates having a length reaching the compression portion located at the rear position in the rotation direction are fixed to each compression portion, and the rotation axis of the upper rotation ridge is the lower rotation adjustment. It is arranged in a downward direction at a predetermined angle from above the ridge toward the upper surface of the ridge, the upper rotating ridge is provided with a drum-shaped rotating frame, and a plurality of compression portions are provided on the outer periphery of the rotating frame. At the same time as forming, the bases of a plurality of compression plates having a length reaching the compression portion located at the rear position in the rotation direction are fixed to each compression portion, and the rotation axis is from above the lower rotation ridge body to the upper surface of the ridge. The rotation axis was arranged in the upward direction of a predetermined angle diagonally upward from the side of one side surface of the ridge to the large diameter portion of the upper rotating ridge body arranged in the downward direction at a predetermined angle toward the ridge. A rotating disk member having a shape along the outer peripheral portion of the lower rotary ridge and having one side surface of the ridge can be replaced and exchanged , and the upper rotary ridge is provided on the outer peripheral portion of the lower rotary ridge.
