My 650/750 manual says to tilt the seat up during storage. Any significant amount of water would drain out rather than puddle and freeze. In any event with most newer JD's with the switch under the seat, having it freeze shouldn't affect the switch. If anything a heavy frozen seat should activate the switch more so the than lighter seat. Older JD's/Yanmar's had them in the seat which was a horrible design and that would be a huge issue.
Cold seats are a pain no doubt. I think of that every time I park my butt on the frozen metal pan seat on one of my 8n. But that's what happens in Winter. I guess up here in the North we don't think about it much.
My 8n's were built in an era where leaving a tractor out in the elements was just what you did. Even so there are times when it behaves badly after a rain. All of my JD's either get covered or are stored indoors. No matter how it was designed, you can't beat mother nature. Either you need a tractor cover or a tarp. A $10 Harbor Freight tarp and a package of bungees will keep it running better and longer. Weather is a killer for any equipment.
A can of electrical contact cleaner/lube should help clear out any residual water and help it from getting corroded. CRC556 or WD40 would work too.
