Hallo Guys,

Can anybody give me a idea how to set what on my 9650sts to stop breaking kernals harvesting dry corn.

I have cropangel concaves in. Rotor speed is a out 280rpm fan is about 1150rpm. Sieve is full open, chaffer is about on 12mm. Concave is 45mm open. All other combine settings is as per manual slowed and changed.

My grading still comes back with 5% breakage.

Any suggestions plz?

The only solution to broken kernals is slow rotor speed and keep it full (cushion). You might try closing the stripper plates as tight as possible to take in more trash!

Some corn just cracks up real bad. All you can do is run the rotor as slow as possible. IDK about the crop angel rotor - essentially you want a gentle concave in real dry corn. Make sure its got lots of open area to let the kernals out of the rotor area ASAP.

Nothing you can do with the sieve area to reduce cracks - cracking happens in the rotor/concave. At that point, sometimes turning up the air to blow the broken kernals out (maybe) - but then you are losing that weight anyway.....
Are you sure you are on the slow side on the feed accelerator? Big pulley on the feed accelerator. The early 9650sts books had a misprint and the feed accelerator belt setting were opposite.

I will have a look at the big pulley, will be interesting to see in my manual what it says, maybe i have the misprint one, thanks for all the assistance sofar.
