BX-
I am one of the infamous ones on the JD forum who has traded often. I receive good natured ribbing at times for my neglecting to keep any tractor beyond a year. I have been where you currently are. I started with an X595 tractor, which was great when I had a large yard, then I moved. I then had more property but very little of it was grassed. I bought a small FEL for the JD and found it inadequate for my needs. My friend who is a JD dealer sold me on going bigger, to a 4310, which was great but underpowered for its size and my hilly terrain. I then went with a 3720 which I liked a lot, but had an opportunity to trade for a 4520 which I did. It was a great tractor, but so large I could not fit about half the places I wanted to work, so I sold it and bought my second 3720, which I currently own. I have 120 hours on it, which is the highest hour count of any tractor mentioned. I love it, but have been looking at a smaller machine recently, as even my 3720 is too big for some of my work. I probably will keep what I have because I like it, but can say personally that I have owned at least five tractors of late before I hit the right one, and I am still not 100% convinced I have it right yet. The other thing of course is that our personal needs change. For me, had I not moved I probably would still be mowing and such with my 595, but with changing circumstance, I needed something different. Welcome my friend to the slippery slope.
