I'm not sure about the 1-series, but all of the X-series. And they use the same mowers and blades on both series of tractors. Perhaps someone with a 1-series can clarify this for us.
I can't speak for the 1 series, but I don't see how it could work on a 2520/2720. They are basically the same exact machine as my 4115, and I can't have both the front hitch and MMM mounted at the same time.
