After using my 700SE the last few snow storms to clear the laneway I've noticed that after it gets warm it doesn't want to start. Won't even make a noise. I'm guessing it's because the machine is getting hot, but it doesn't do this in the summer, when working hard on the trails. I'm not seeing snow build up on the rad either. It did it today at the gas station, after plowing the laneway. Has anyone else had this problem?
