Is the crop tough and green straw? Assuming one of the two or both this time year. I thought green would have been out after killing frost here 3 weeks ago but still have some in field today. Open bottom sieve and turn up fan a bit. I run concave bit more open and rotors faster than book settings on rotary than book settings. Been running a CX last couple years so my memory on CR may be bit off.

I use 2 setting on a similar combine. You have that switch that allows 2 different settings. When climbing a hill, I toggle the switch to lower the fan speed (about 100) and open the lower sieve. When on top I toggle the other way. It is a bit of pain setting up the 2 settings but eventually I get them where I want them. Don't forget concave clearance is on 2nd page of the setup - so keep it the same on both toggles if that is what you desire!


It is the cheap man's version of opti-clean! The reason for the occurrence is the change of the tilt of the sieve which changes your fan throat characteristics. Going up hills, you drive the material further back so you need to decrease fan speed! I believe that is what "opti-clean" software option does. It coordinates fan speed with the pendulum position (JMO).

It is not What you know, it is WHO you know that counts! Currency is a UNIT of debt - not value!

Where is this switch? I do this manually on real hilly 1/4. I think it’s worth it, especially in canola but what a pain in the as*.

On my 970 it is next to the feed reverser switch. Has a combine with the number 2 on it.

The other important matter to note is that in one of the menus, you have to turn the ACS "on". If it is "off", the ACS icon will never show up on your monitor display. I can't remember where that option shows up (toolbox?)? Failure to turn it on, renders the physical button "useless".


So look at your display and make sure you have an ACS icon that shows up with all the rest o the icons at same level toolbox etc. If it isn't there, you have to make it appear!
