PROBLEM TO BE SOLVED: To provide a walk-management machine that enables smooth switching when switching between a forming posture to form ridges and a storing posture to be stored, by providing a ridge forming sheet at the rear of left and right tillage rotaries, and also has a simple supporting structure.SOLUTION: A walk-management machine includes: left and right tillage rotaries 3 rotatably supported at the lower side of a machine body 2 and a flexibly changeable ridge forming sheet 4. The ridge forming sheet 4 is supported at the rear end side of the machine body 2 switchably between a forming posture positioned at the side right behind the tillage rotaries 2 and forming ridges, and a storing posture positioned at the upper side of the tillage rotaries 3 and stored therein. A mounting member 41 for mounting the ridge forming sheet 4 is provided at the rear end side of the machine body 2. An attached part 42 of the ridge forming sheet 4 switched to the forming posture is removably mounted at the side part of the right and left one side of the mounting member 41. Also, an attached part 42 of the ridge forming sheet 4 switched to the storing posture is removably mounted at the side part of the right and left other side.
