I guess I'd just like to vent with you folks a little, and also ask if all tractor manufacturers are like NH in that they design their tractors such that you have to buy different wheels for turf and ag tires? I bought my first (and only) tractor used a few years ago (a NH 1925) and it had turf tires on it. While they worked ok, I decided that ag tires would increase the tractor's efficiency. When I went to buy some ag tires, I learned that I couldn't just buy the tires, but had to buy all new wheels too because the ag tires would not fit on the wheels that I had for the turf tires! Can anyone suggest to me that this is anything besides a marketing ploy to sell more tires/wheels? Is there a real technical reason that this has to be the case? I bet not. This sure chaps me off and I was wondering if all the other manufactures of these compact tractors do the same thing? 45er
