As posted by budweiserfarmer, Yes it works fine. The snow breaks up to a fine power and blows right out. The perticular field that year was low ground that would be flooded out in the spring - winter harvest was pretty much the only option to salvage what was there. It must be cold for the snow to not melt and stick. The field was free of rocks - rocks could pose a problem buried under the snow . . .  if you know what I mean :0 I have harvested corn with snow on it a few times - at that time, mostly at night, so it would blow out.
