50" mower deck for JD 420-430

So I am in need of a mowing deck for my old 420. It would have originally came with a 50" or 60" shaft drive deck. I bought it without a deck and am trying to decide if I want a 50 or a 60. I had a 430 with a 60 and honestly thought it was too big for my yard. I don't have an acerage or anything big I just like the older bigger garden tractors. I have never used a 50 or seen one for that matter, but I do know a guy that has one for sale, at a premium of course. I am wondering if anyone on here had used both and how they compare. Do they both mow good? Is one preferable? I know the 50 isn't much wider than the tractor wheels, is that an issue? Is there anything bad about a 50 other than its not as big as a 60. I am thinking maybe the 50 wont scalp my yard in places the 60 did, and will fit it tighter places. Were the 50" decks just no popular because most people wanted to mow bigger areas or is there something else I'm missing?? I even talked to a guy who has been buying and selling this stuff for 26 years and had only ever seen one 50" deck! Also, wondering if a 50" from a 318 or similar would be able to be retrofitted with the shaft drive assembly or not. Thanks.

I have a 430 with a 60" deck that I have never mounted cause I am using it for other chores, but I have a 140 with a 54" deck and what most would consider a "why bother" yard cause I can mow it easily with a regular push mower. Didn't get into JD garden tractors for that anyway. The 54" deck is a pain in my yard and we don't have much landscaping to negotiate around. It's fast, yeah, but unless you have double gates or have widened them the size can be a pain. Mows good, but I'm on the lookout for a smaller deck, like a 48, so I can extend my tractor/lawn/greenspace therapy time and I consider mowing part of that. The 430's previous owner was using it and the big deck to mow a sizable ranchette-type acreage and I see where it is perfect for that. Good luck finding the deck you want...or upgrading to another tractor in the herd just for mowing.
