PROBLEM TO BE SOLVED: To provide a ridge forming machine in which a working speed can be improved and efficient ridging work can be performed.SOLUTION: A ridge forming machine has a banking unit 40 for supplying soil in a banking-up state, and a forming unit 41 for pressing the soil banked with the banking unit 40 and forming a ridge, in which the forming unit 41 includes a top surface roller 413 for passing on the ridge forming place having the soil banked-up with the banking unit 40 while rotating, and a conical disk 411. In the ridge forming machine, the banking unit 40 includes a tilling rotor 408 for flipping up the soil excavated by multiple tilling claws 401 provided in a horizontal rotary shaft in the direction intersecting to the ridge to be formed to the ridge side and banking it in the ridge forming place. The tilling rotor 408 is characterized in that the base side where the driving force is input and the tip end of a formation ridge side are rotatably held by bearings, and the bearing of tip end of the formation ridge side is positioned in the base side where the driving force inside from the tip end of the tilling claws 401 provided in the tip end of the formation ridge side is input.SELECTED DRAWING: Figure 1
