JDTank,
I have owned and mowed extensively with an X series 485,495,720,and 595. I have had both the 54 and 62c mower decks. I am a big fan of the X series tractors. They are Cadillacs and awesome machines. My online infatuation with them is well known, but I can say that the 2320 is a better mowing machine than the X series on the lawns that I do. It is faster, even in A range, the large tires make for a smoother ride, it SEEMS to have more power, though this likely is an illusion, it lacks a RIO switch and cuts as well or slightly better. I cannot peak to the 2210 or 2305 and how it mows in comparison, but this is a very different machine than a 2320. My point with interjecting this is that a potential buyer who may be interested getting a true compact tractor (I view the 2320 as the initial true compact made by JD) and a sub compact or top end GT but is afraid it may not mow well, may be interested in considering something like a 2320 for only a tiny bit more money. My dealer even was advising people that the X series was a "10 times" better mowing machine than a 2305 or 2320 but is now second-guessing that advice. While X series tractors are great mowing machines and a true pleasure to use, the 2320 as an example is a great mowing machine and worth consideration.
