I know they put this deck on some zero turns and probably a walk behind too. I have a chance to buy one for my Toro 117 Groundsmasters. Its never been used. He wants $350 for it. I do remeber this deck has two big blades not timed and one tiny little blade ahead of them in the middle. Its a dedicated mulching deck and none of my current customers request mulching. But it would be nice to have an extra deck around that fit both of my GM 117s.
