make sure your bottoms sieve isn't closed too much and your air isn't turned down to low.. that was the problem I ran into when switching varieties in wheat one day.. but i don't know if its the same for canola or not
Combines AFX looses

you are right in oats barley and wheat it works but on canola you can not play with air too much. I, just woundering how JD STS 9880 dooing they has same sieves as 5 staw walkers machineIJ

Hi Shaulinis. Did you ever get those rubber seed platesIJ When you were in oregon a few years back, did you combine any grass seedIJ Well, this year we had a problem with a heat wave coming through just when the grass was setting seed. As result we had a very miserable time setting the machines. A lot of light, but viable seeds, a lot of partial seeds, etc., etc. Even with our old 1680 we could out power the cleaning unit. Basicly you're just stuck in a situation where you have to run the machine at the capacity of the cleaning unit not the rotor and threshing unit. When I'm in a simular situation to what you describe, I usually run a few cover plates to get everything rubbed apart, seems like those sort of conditions require a little extra rubbing to get the smaller grains and seeds out. Then just run at what ever the chaffer and air blast will take. It may be kind of tough to run the machine at such a lower limit than you're used to, but in the end it seems to save a lot of grief. Hope you can get things figured out.

Our 8010 worked very well in ryegrass. Ran it at about 60%power.Rotor at 700ars.fan at 500ars concave at 12. precleaner almost closed.chaffer at 10 or half inch. sieve at 5 .Yield about 1200 pounds.

O yes we got those rubber covers also we use striper header for ryegrass. Together it works much much better. F.E last season it took to us 20-30 min to unload grain bin or ryegrass this season just 5 min. About this season: we newer had problems with threshing (de awning etc). The puzzle I'm trying to solve: How to reduce garbage coming from rotor and do not overload sievesIJ We played with different concaves wanes (standard tricks) doe you know some moreIJ About Oregon: the farm I used to work in had some grass seed but I was not involved in it so it is not much I can ay about it.

Just general comments for any rotary combine harvesting rape or canola. You have to do what you can to limit the amount of chaff and chopped up stalks (MOG) getting onto the chaffer. You may even have to blank off some of the grates. Slow the rotor and advance the vanes or whatever, to get the stuff out of the cage with a little damage as possible. And as mentioned, you have to blow the trash out, you can't screen it out, so open the bottom sieve and use as much air as possible.

It's very difficult to try to help solve a problem without being there to see what is going on first hand, but there is a lot of experience on the forum board, so hopefully someone with first hand knowledge will come along and get you going. In the mean time, I think there are 2 general theoretical ways to approach your problem. 1 is if the "garbage" is large sized pieces and some unthreshed grain or seed, it is falling through the concaves too soon. Generally I would tend to blank off, or use cover plates on the first concave. (in your case, module) This should help rub out more of the unthreshed grain_seed, and reduce the size of the chaff so the chaffer and air blast can deal with it in a more consistent manner. 2 if the "garbage" is very small and light weight, and there is many cracked pieces of grain_seed, then I would tend to slow the rotor down and open the concave_modules. Sometimes an overloaded chaffer and inconsistent problems with the machines performance can be traced to something so simple as not keeping the machine full. Example: If I run my 1680 too slow in fescue grass, it will load the chaffer heavily with long pieces of straw, and the rotor cage will plug between the concaves and the grates. But if I push it a little and keep it full, those problems go away, and all I did was speed up my ground speed. Dont know if any of that helps you in your situation, but I'm trying.

The point is that we newer had this problem with AF2388 or any other smaller combine it slows down when it is whet or higher yield etc. AFX has power more then enough. Rotor is driven by gearbox so there is no belt slipping etc. Usually what we do set the combine for best conditions and then changing the ground speed according sieves looses monitor. But it is a pity to slow down such a monster

good point we shall try it
