I understand, John. In fact our forecast calls for a low of 25 tonight (and it's usually colder out here in the country than in town), and I've seen it as low as 10 here once in the past 7 years; however, my tractor is indoors, even if the water in the tires froze a little slush wouldn't hurt anything and solid ice probably wouldn't hurt anything if you didn't move the tractor while it was frozen, and I have no intentions of using my tractor when the temperature is below freezing, so I'm convinced I have nothing to worry about and thought he might be the same. Now if I planned to use my tractor in sub-freezing weather, that would be a whole 'nuther ball game./w3tcompact/icons/laugh.gif
