Just bought this tractor. It has a 54D belly mower and a CX 200 Front end loader and Imatch 3 point.
Tractor: Engine is strong, seating is comfy and controls seem to be in the right place. Hydrostat works flawless. Loader and mower are very easy to install/remove. I love to operate this little guy.
Issues: The tach/hour meters quit so if you are buying used don't take the hour meter to heart. Look at condition closely. The front u-joint on the main drive shaft is very difficult to grease but also very important to grease.
Mower: 54D mower will hog through anything and IS wide enough so you can mow close to trees and such. I don't like the anti-scald wheel setup but I do like that you can lock the deck up high and then use a 3-point attachment with the mower installed. I think the mower mows the grass too short which may be operator error but I am still working this out.
Loader: It is strong and fast but since the tractor only has one pump the loader will only do one thing at a time. (UP/Down or curl but not both at once.) No issue unless you come off a real dedicated front end loader. Also I do wish you could "float the bucket" which you can not do as it would make final grading easier, but no big deal.
It has done everything I have ask it to do. I also love the dealer support for JD. The tractor needed a bit of work when I bought it and my dealer had every part I ask for in stock! I also thought that parts prices with reasonable. Try that with some grey market tractor!
