Wind chill does not affect a machine. If you measure the temperature of the cold engine block or battery of a vehicle in your driveway, you’ll see they are the same as the ambient temperature, regardless of the wind.
Wind chill is a measure of how fast a warm surface is cooled. You can't cool a surface of an engine or radiator that is at ambient temperature to less than ambient no matter how much air you blow on it.
Wind chill between the freezing point (0 degrees Celsius) and minus 27, the risk of frostbite is low. But a wind chill factor between minus 28 and minus 39 C will cause exposed skin to begin freezing in as little as 10 minutes. And at minus 40, you’re in a high risk situation, with exposed skin beginning to freeze in only five minutes. Machines simply are not affected.
