What mower decks fit the 2210 john deere?

I'm trying to find out the same thing, but am currently only interested in the 48" version to replace what I currently have. Local dealer provided an answer that there are 3 models..2 smaller than the 48". The model number for 48" is bm18365. You can still buy them new for around $1,029.00 plus tax. Am told that you cannot order certain parts for this deck as they have been discontinued. Hope this helps.
