This past harvest had wheat that had really been baked in tougher then I've ever dealt with before as usually all the varieties grown here are pretty easy threshing. I had to have my rotor speed at max and my concave at 0 which sucked alot of power and growled extra at night.
So today I started wondering if I had put in filler plates and backed off the concave would that gain me any capacity or not? The combine came with 4 cover plates but they've never left the pallet

We run filler plates with wheat and it seams to help. Depends a lot on variety as to white caps, never had to run concave down to 0 usually run 5/16, give or take. There not bad to put in or take out and well worth the time switching for barley to wheat.

Ok. It would make sense that it should use less power, just never needed them before so didnt think about it till after. Wheat is often in the 90's bpa so hopefully doesnt give up too much separation

We always ran filler plates in our Cr. Never really noticed any capacity loss but had less return plugging issues. Never did 90bu wheat though

Had to run 2 filler plates on my 9.90 on 1 variety of wheat this year. My 9070 has a mad concave and dont use any with it. It's amazing how clean the sample was without them. Going to get a set fir the 9.90.

It was a tough year for threshing, dry with smaller seeds on the wheat. Is the re-thresher on the CR good enough to get that stuff out second time around if you tighten the bottom sieve? I had to run a high return last year and it slowed my output slightly, but on the Claas the return dumps back into the cylinder. If the re-thresher won't do it filler plates will help. Heard good things about the MAD concaves as well, concaves can make a huge difference. I remember when I ran Case machines and we had some harder threshing wheat and they brought out a guy from the factory with some prototype hard-thresh concaves. He nearly made flour with a rotary combine on the same settings I had been running previous, we had to slow things down a bunch to stop the cracking!

The rethresher is decent i guess but I'd rather not rely on it. Never put enough in it to plug anyways. Some of those hard thresh concaves may as well be a filler plate with how little opening they have to let grain through, but theres something for every condition I guess. Every other year I've been able to do 3/8 ish concave with the extension out which frees up alot of power but I'll have to dig out the filler plates just in case for next year then |

I made a filler plate for the extension on the 9070 and used it for flax when I had the original concave in.
The 9.90 is a twin pitch rotor elevation and the 9070 is S3 rotor. With the added hp the 9.90 at night is better. Didnt really get a chance to really compare them,wife drove 9.90 and son was on 9070. Just guessing maybe .5 to 1 mph faster for 9.90.
