Welcome to the forum Orchard Tracker ....
I have only a windshield. BUT, that along will knock off many degrees of butt biting cold.
Curtis is the manufactor who makes the OEM Kubota Glass Windshields & Frame.
Curtis is a company with a big backbone. I've seen many products put out by them, NOT saying others are bad. But would be worth going ahead and getting XX Duty Shocks with or without the heavier Curtis Cab. For just the windshield alone. That part by itself is heavy, counting the frame and all. I have the steel top and the windshield, works wonders for knocking out the cold.
Also have a sliding back glass on our RTV 900.... ( keeps cold off the neck area)
What ever you choose, it will be a big plus on knocking out that cold weather.
Have a nice day and feel free to join in on any discussion !!!!
