I imagine that you could add tint film to the front window, but the doors are all galss and rimless. My ac fix cures the problem. Believe me, I have put the ac to the test and it passed with flying colors.
Just remember to close the doors before moving the tractor. Not closing them can be a painful and expensive lesson. I have learned that lesson first hand!!!
I am not going to elaborate any more on the above statement, nor am I going to start a thread explaining my stupidity. All I will say, the glass doors are expensive and they are most certainly safety glass.
