I don't know about the JD with the wings, but the Toro has wings that can be lifted independently. I think the hustler used to have a mower with wings as well. The center deck can be configured to a narrower deck as 48" and the wings are smaller. The center deck can be the only deck mowing while the other two are both riased. Or only one wing deck might be raised. I have seen some Toros with center deck and only one wing deck. The Toro we have for the town has several wing decks and the center is three small decks in V-alignment. All of the decks are narrow, I think 30" per deck. With so many small decks, a really nice cut is the result. Those machines also can tilt the decks vertically exposing all of the blades for removal to sharpen. A nice and labor saving feature.
Right now, i don't know anybody else making the multi wing mowers other than Toro, but I'm sure they are out there (John Deere as stated above).
