PROBLEM TO BE SOLVED: To provide a leveler operation link mechanism of a tilling attachment, which can also correspond to a folding type tilling attachment, has a simple structure, can easily be maintained and checked, and has a good leveling performance. SOLUTION: This leveler operation link mechanism of the tilling attachment is characterized by having a leveler link mechanism 4 having an energizing means 5 for upward energizing a second leveler 17 and a leveler-switching mechanism 6 for switching into the state of a soil-covering work position or a leveling work position, wherein the leveler-switching mechanism 6 is switched by normally or reversely rotating a lock plate 61 longitudinally rotatably disposed on the working machine main body side by the extension or contraction of a cylinder 60 to engage or disengage a dent portion 610 disposed in the lock plate 61 with a lock pin 43 disposed in the first link 40. Thereby, provided is the leveler operation link mechanism of the tilling attachment, which can ensure the folding space of a folding tilling attachment, has a simple structure, and has a good leveling performance.
