I bought my tractor because I knew if I bought another motorcycle, I'd be likely to kill myself on it at my age. It's a safer toy.
In regard to the ice problem on those windows, I wonder if a fall application of rainex, or maybe Glass Wax (if they still make it) might prevent that ice from sticking, at least to the parts you could reach with the stuff..
A judicious use of an electric heater (the radiant type) facing the window from inside might get you fixed a section at a time, but at a pretty high cost..
