Jon, I'm looking at the other side of the coin, I guess. 

Many folks who have no-tilled corn into good wheat stubble that was harvested by a combine with no chaff spreader behind the cleaning shoe can show you a definite, visible difference in the corn which was planted in the windrow of chaff compared to corn which was planted behind a machine with a good chaff spreader.

This is not even mentioning the straw. 

If that was our business, I would sell you a spreader that works for a whole lot less than $500!

I think I've about beat this spread-the-windrow thing to death.  Thanks for the comments.
