PROBLEM TO BE SOLVED: To provide a ridger solving the problem that ridges of a desired height cannot be trimmed unless a ridger travels relatively long distance after beginning ridging work. SOLUTION: This ridger 1 comprises a ridging rotor 2 for making an earthing up by tilling a farm, a ridge-trimming plate 3 for forming ridges behind the rotor 2, a supporting wheel 23 keeping the height of the ridge-trimming plate 3 and a frame 4 integratedly holding these components. In this ridger 1 designed to join a three-point link on the side of a mobile farming implement for traction and lifting, the frame 4 is mounted with left and right lower link shafts 19 rotatably joined to left and right lower links 15 of the three-point link and, above the left and right lower link shafts 19, a junction 10 idlingly joined to an upper link 14 is provided.
