I have a 44" deck on my 2518 now.  It cuts well and is in good shape.  I was thinking of trying to track down a 48" deck for it if I can find one at a good price.   Not so much for the size but it just looks like a better deck.  
I only base that on the fact that the more expensive mowers usually come with decks with the swivel wheels like this on has. I guess that's so it can ride on the ground. Is that really better?
