I was also looking at the JD units and I am not sure if the 23hp is the same as the 32hp unit 3203 and I could not belive how loud and jerky the hydro was! After a lot of research and test driving I realized that series is a very basic tractor and after driving the 20 series it was very apparent that I would not enjoy my seat time on the 3203.
Not knocking any brand but I went from test driving the 20 series to the basic 3400 kubota and it was much smoother and more quiet.
Word of advice, You will be in the seat a lot of hours so test drive, test drive, and test drive again before you pull the trigger.
Local Deer dealers have the 2305 over priced in my opinion over 15k for tractor loader and mower.
