A 42" deck will hook right up. It will use a different belt, but other than that it is a breeze. Make sure the deck is for the early tractors with the center mounted pto rather than the later cone clutches. While the newer decks will work, the pulley diameter is a little larger and you will loose some spindle speed unless you change pulleys. Not much difference, but it will be noticeable if you have ever used the other one.
