I have a 2005 JD 4120 with about 1000 hours on it. I use 4wd whenever I am operating on soft ground or doing front loader work. That ends up being most of the time. About the only time I have it in 2wd is when I am bush hogging fields in the summer when it is good and dry. I bought the tractor new and the only thing I have done to it as far as maintenance is change the engine oil and filter every 100 hours. I also changed the antifreeze last year. All the other fluids and filters are original, and it has never leaked a drop. I always make sure to take it out of 4wd when I have it on the road, which don't happen too much.
Back when I bought it, I checked out NH and Kubota. I am glad I went green, and glad I got it when you could still get an American diesel engine pre tier-4.
