1250 ish.
The drive remained the same, simply a gearing change in the gearboxes.
Guessing they wanted to keep the two drives (cylinder, rotor) the same.

I often see little change in my crops with rotor speed.
Okay with cereals the challenge is getting the grain out of the straw, especially hard when the straw is green or tough. You want to run a fast enough rotor speed to spin it out and enough open grates without letting too much chaff that will overload the sieve. It's a balancing act between rotor and sieve loss which is adjustable because of the hydraulic rotor covers of the Claas. Of course you can adjust rotor speed, but I suspect nearly all cereals done with a Claas hybrid up here are at max rotor speed which is about 950 I think. Mine go to 1200. With any other combine on the market changing rotor speeds affects threshing, but of course with a Claas hybrid the threshing is independent from the separating. You already knew this, just explaining it for the lurkers.

So when I am doing wheat or oats I am typically running 1200 rpm rotor and closing rotor grates as it gets drier and then opening them as it gets tough in the evening. Only time I move rotor speed down is when opening or closing one set of rotor flaps creates too big of a change in the balance between rotor and sieve loss. Of course I am always experimenting with all sorts of settings including the old rotor speed and it is painfully obvious that the slower speed is way less effective. AND when I talk about balancing losses I mean to keep them both as close to zero as possible. I am running sensitivity at 80-85 and there is almost nothing on the ground. Gonna do some pan testing to see how much lower I can go with the sensitivity and keep low losses as I know some guys are running 60-65 setting for that, but in wheat this thing is approaching 2000 bu/hr early and late in the day and maybe down to 1500 when straw is breaking up worse. In oats we had both machines doing 2300 bu/hr without even pushing because the trucker couldn't haul it a half mile to the yard any faster.

Won't use the extra grates or higher speed in corn/soybeans/canola/peas, but in cereals it is a big-time improvement.

I absolutely love the adjustability of the Claas.

No insider stuff, no solid knowledge other than knowing you are not a betting man.

Yes it's in the gearboxes.

Without sitting in the seat I seem to recall that mine goes to maximum setting of 1220 RPM, which gives an actual working speed of 1180-1200. I also recall the older ones could be set for 980 or maybe 1000 with a working speed of 950??? It doesn't sound like much but it makes a difference.

What are other guys running for sensitivity on rotor and sieve?

Sorry I meant 2019, you most likely would win the bet on 2020.

I often don't know what day it is, but now appears I have lost a year...

When your machine says 1500 bushels per hour how many bushels are you actually getting in the bin per hour. I have been doing the trucking and it seem like even when we unload on the go and try agerage 1300-1500 bushel per hour on the monitor is ending up being maybe 800-1000 in the bin per hour. I would have to pull out of the cebis what it says it was averaging. I may be off in this but it never seems to be close to the reality of what is in the bin per hour even when it is calibrated fairly close. Just wondering what others are seing.

1/2 correct, the speed is no advantage in peas as 600 is all you want but the 20% more separation makes for engine power limit and very, very close to feeder max capacity (run 170 feeder depth as a temporary power and feeding research project) and virtually zero loss.

Guys like you and I love the adjustability but more need to know the incredible flexibility only Claas allows, you can not depend the auto setting will always do the best job but the operator can fine tune readily.

Seedcleaner did change the dummy concaves to separating concaves, donít think itís a terrible job.
