Gleaner K corn and soybean special setup for oats

For a couple of years now I have been trying to harvest oats with my gleaner k with little success it blows half of the oats out the back and my fans are to the slowest speed possible I've even thought of removing the belts. I'm running out of ideas, please help!
 
have you tried opening the sieves more to slow down the air? does yours have a way to slow down the fan more like different pulleys/sprockets? the machines I have can be adjusted several different ways maybe the A/C can be as well?

Glenn,
Went to my neighborsand asked them your question. They never owned A model K. They however had and "L", before it went to the scrapers. He thinks they may be similar.
He said to check for a "variable shieve" on the fan belt. They said the "L" had a lever in the cab, that you shoved up and down, to open or close the variable shieve, to control the speed of the fan. He also said to check the "air control" inside and behind the fan. I have seen some that you can direct the air flow to the front or back of the screens. Directing the air to the "Tailing screen" would be try. as I think this would allow the lighter oats to fall through the front of the full screen.
He expressed that his problem with Oats was that because out the amount of straw, it was hard to get the oats to shake out of the straw.
Are you certain your blowing the oats over the screens and not going over the straw walkers?

What kind and how much is going in the tailings return? There are slides on the fan sides to open and close if it's and older K with 2 fans. If new would have the squirrel cage fan that used a chock to control air, think the later ones had the squirel cage anyway. Sure it's blowing out or riding out over the shoe? Do a quick shut down, blown oats will be well behind the shoe, walked out will be right underneath the back of the shoe. Also could be walker loss as one of the others said.
 
You"re going in the wrong direction. Open the chaffer, set the sieve to what the OM recommends, and put a lot more air through it. Shutting down the air will plug the chaffer and sieve and the oats will shuffle over both and out the back of the combine.
 
Glenn,
I believe I can help on this one.
First off the adjustment for fan speed is a crank handle in the cab. You MUST adjust the speed with the combine RUNNING. If you do not have the belts running when you adjust the speed, you will bend the adjustment controls. Check to make sure that those controls and the pulleys are in line and can move the speed the full range.

Second the belt needs to be new to get the slowest speed. Because of it's way of being adjusted this belt wears on it's sides and gets narrow and gets stretched out. I remember I was able to get a much wider range of speeds with a new belt. I think (been more than 10 years) that you gain in the slow speed range the most.

Now for the third one, my machine had 2 sets of "shutters" that you could close to limit the air that could get to the ends of the fan. They were galvanized steel. I do not think that I ever had to close those for oats. I believe that they were more for stuff like grass seeds.
The last year I used mine, I remember getting 100 bu per acre in oats so I am sure I wasn't blowing many out the back! The manager at the mill said mine were always the cleanest oats he got in (made me smile).
I hope all this helps.

2 cranks!
1 high on panel for cyl speed. That one runs a small sprocket that has a bicycle style chain down to the sprocket on the cyl driving sheave on the main cross shaft.

One lower and towards back (right) for air speed. It screws into a rod that goes thru a bunch of linkage the runs to the back of the machine where the air speed is driven.
My machine was a 1970 K corn bean special like he asked about. Has 2 fans, one fixed speed for top and the second variable that was for the chaffer area.
