Combining on a side hill with a non sidehill 6620

Does anyone have any advice on how to limit the loss out the back of the sieves when on a side hill? I have a 6620 6 row head and have all the grain falling to the downhill side and running out the back before it gets through the sieves.
 
You can try a couple of things. Put rubber flaps on the outside shoe supply augers just behind the front auger pan. This will help to get more grain towards the center of the chaffer. They flip the grain as it comes off the pan. Bolt extensions to the dividers between the sections of the chaffer. This will keep the grain from sliding across the chaffer and overloading the downhill side.
 
A JD 6620 is NOT a six row combine on any type of hill. Your just going to have to drive REAL slow on the side hills.

Another issue will be that the crop mat is not even so the air will flow out of the side that does not have any material on it. So the lower side will not spate the chaff and grain out.
 
My old 95 corn special had a metal strip about 4" high that bolted to the top (front to back) of the shaker bed to keep the grain from going to one side. It also had a piece bolted to both outside edges of the shaker bed 1/2 back to push grain off the side to the center of that sieve section (like a wing). I do remember seeing a 6600 with this set up on it years ago. It might be worth a look under special equipment in the JD 6620 parts book, You may find something like that on it. Bandit
 
Thanks for all of your input. I had another guy tell me once you could reverse the outside augers to run opposite and would distribute the corn more to the center of the shaker. I wonder if this will also slow me down on the flat acres. Slow is what I am hearing regardless?
 
I had a 4420 with a 4 row wide cornhead and when I got on a sidehill in decent corn I would open the chaffer and sieve a little, the sample will not be spotless but you'll be able to move a little faster.
 
Open up your top sieve to where you can put your index finger between the openings, or possibly a little more. In hill conditions open up the rear section wider than the front. Run all the air you can run and open up your bottom sieve somewhat to allow the corn to fall through sooner. A tight top sieve will cause your problem. You may get slightly more in your return but that is an acceptable compromise in hill conditions. Always open your top sieve in hill conditions. Mike
 
Does anyone have knowledge of where I would look for these types of "Special parts" The idea sounds like it would work, but haven't been able to find anything? I would be interested in the taller dividers and the divertors on the front.

You can make the taller dividers yourself, just use heavy gauge sheet metal.
 
I've seen a couple of combines one MF 550 and a F2 with a blower and duct work attached to the the rear thresher housing it had a pendulum that directed the air to the left or right depending which was the downhill side it was claimed to help move the grain toward the upper side of the screens,google hill side grain blower to get a look at one
