RIDGE-FORMING MACHINE

PROBLEM TO BE SOLVED: To provide a ridge-forming machine which has a ridge-forming tool for forming ridges with soil tilled with a rotary tiller located behind the tiller, has a gauge body which contacts a field for supporting machine frame load, is attached to the rear portion of a travel member, is moved on a field, forms a ridge on the field, can repair the collapsed upper side of the formed ridge, when forming a ridge adjacent to the formed ridge, while partially overlapping on the ridge formed, and can efficiently ensure the press force of an upper side-forming tool for the upper side of the ridge. SOLUTION: This ridge-forming machine includes an upper-side forming tool 66 for repairing the collapsed upper side Ra of the formed ridge R2, and disposes the upper-side forming tool 66 on a support member 67 which is erected vertically on the gauge body 37, when the ridge R1 is to be formed adjacent to the formed ridge R2, while making a part of it partially overlap the formed ridge R2.
