PROBLEM TO BE SOLVED: To provide a walking type ridging machine for farm equipment, capable of forming a flat ridge and a round ridge by one machine, and facilitating the exchange therefor. SOLUTION: This walking type ridging machine for the farm equipment has an upper plate 72 attached to the ridging machine 22 so as to be overlapped with right and left ridge-forming plates 81 and 87, and a pushing member 73 attached to the upper plate 72 and for pushing the upper plate 72, and the upper plate 72 is elastically deformed into a plane shape or a curved surface shape by the pushing member 73. By reversing the pushing member in the upper and lower directions, two kinds of ridges are formed by one ridging machine. As a result, the conventional preparation of both of a single-purpose ridging machine for flat ridge formation and a single-purpose ridging machine for round ridge formation is not required, and the manpower for exchanging the single-purpose ridging machine for the flat ridge formation with the single-purpose ridging machine for the round ridge formation is saved to improve the convenience of the ridging machine.
