Combines settings on sts

I think you will find the settings in the book to be pretty close. To me the STS machines have a much larger sweet spot than the walker machines. You might have to speed up the rotor and tighten down the concaves when conditions get really tough but I'm sure you already knew that.

Secret in harvesting with the sts is keeping the rotor as full as you can.The settings are what I run with on 3 9750's with 36ft drapers and concave with 2 filler straps positioned were the returns dump back into the combine and all the seperator plates installed (dry straw especially)Running 930R's might make the setting's different because you can't get as much matieral.I've even heard of harvesters getting restricted with the 930R on a 9650sts. The book is not vary good on the settings chart. 40 bushel wheat average straw dry concave-14-16 thick straw-19 Rotor-850-950 chaffer-14-16 keeping it closed tighter than the book says blows more air threw the fixed chaffer up front making crop aloft sooner. sieve-just try to keep the returns down,returns really kills the capacity of a combine in tough conditions Fan-1250-1350 depending on weight and size 60 bushel thick straw dry Concave-20-24 rotor-1000 chaffer-15-16 seive-depending on trash fan-1350-1400 depend size weight trash Some of these setting may vary in way different conditons.I have run sts's sense 2000 and I still learn something every year.

Not trying to start any trouble here but how can you say the book is not very close when all the settings you just described are what the book saysIJ I agree with every thing you said except for the return. I have found it does a better job if you run it about half full.

I can't write everything that I know on a sts,I would be typing all night,in my book I don't remember it saying up to 24 or even 25 on concave,or 14 on chaffer even sometimes in high trash because of not enough air threw the fix chaff,the book says to open the chaff in high trash..etc.I don't think the book says 1350 fan or higher.Some things are close by the book like corn settings are some what closer..I never said there wouldn't be any returns,I said keep it as low as you can.So if you have problems with it being high most of the time there is something you can do to make them lower and still have a clean sample.And I don't really go by the returns bar graph either,I check it myself more often,and the loss monitors to.I could go on and on about whats different and whats not.Maybe when I have more time I will write a book,not saying I know everything,I just have some touchy customers and I get the speed and the quailty to.
