I've been out busting ice on cattle water troughs. With the wind chill it's about -30F. Good thing I put a battery warmer on the honda because I don't think it would of started without it. It got cold earlier this winter and I didn't have it installed yet and it cranked harder than it did today and it wasn't close to this cold. And let me say, honda needs to work on their plastic cab. The cab has been pretty good with the heat until today and I sealed may gaps to stop the cold air but with this cold I have new gaps. It's so cold the plastic has shrunk more and made new gaps. Pretty damn good ones too. Will have to remember where there at and do a little more sealing.
