Ooops!
skobylenski, I'm with you. A snow machine is a snowmobile in other words. We also called them snogoes. Seldom were they referred to as snowmobiles.
However, I think he's talking about a snow making machine which might be used at a ski area to generate man made snow. Shouldn't be too complicated to make snow when the temp is below freezing. A glorified sprinkler basically.
