I've found most dealers of any color are an abundance of caution when faced with thinking that is considered out of the box, especially when any changes to the machine are hard to undo; like pulling rows of fins out of chaffers. That being said; if the answer to what seems to be a common problem is to seal up the combine to keep leaves and straw out, then Gleaner should have started the job at the factory. Instead of sending 'em out with belly screens that fit like a saddle on a sow and a hole by the hydro that a small dog can chase a cat through. I guess that's the beauty of forums like this, the exchange of experiences so we know which side of the fence to jump to; even if some of those jumps, like a few of mine, don't work as well as planned. If the pack appears to be running without the back row of fins and AGCO is following suit with the new ones, guess I'll follow the pack. Thanks for your comments Ed.
