I just have to say I'm really impressed with the XP 850 in about every way. I have been plowing like crazy for the past couple of days and the XP takes it all in stride. It's -10 F right now so will have to see how it does today but I don't expect any issues as it always starts at the moment the button is pushed. It will get an extra long warm up today. I end up plowing out all my neighbors just because it's so much fun...:fest06: We were under a blizzard warning until 7 am this morning and the called off work so all is well with the world!
