what are your sieves set at? How big of a head are you putting on the machine? what is your ground speed? it all makes a difference.

I have a 9610 with 930, ran about 10acres so far so the machine is not shined up yet so i can't run that fast and fill the combine to its capacity, so im getting a not so clean sample myself...I am going 3mph, fan about 1200- 1250, cylinder 750-850, concave 0, pre-cleaner closed, chaffer 14-16, rear chaffer 16, sieve 6.

Once the combine and head get shined up i should be able to go 3.5-4mph and have a cleaner sample. This has happened in previous yrs so im not to concerned just yet

zero in front 12 middle 14 in back 6 under already shined up can do 2.5 mph nice crop but cant get all the wheat out of the heads and then it ends up in the tank concave is at 0 and speed is 700

O also keep it pushed full capacity all u can back off once a while and the screens aren't full all the way across and that seems to put trash in the tank real bad

Your screenings (crack) would be thru the roof then in most varieties I cut


It only happens if you dont feed the combine enough...

You cut plenty of Australian varieties in 115 degree heat with a 9610, have you arcus.. Its the same point I was trying to get thru to combiness. beardless was the only wheat ever cut at that high a revs.

Grab a handful of seed and remover the plastic adjustment cover for access to the bottom sieve. Close the sieve to zero then throw the seed across the seive, open them up until they just start to fall threw (probably around 4 not 6). Increase your cylinder speed but keep an eye out for cracking on the tips of the seed.

Don't overload the return elevator though by "overclosing" the bottom seive!!

You know I havent cut a single arces there


But this doesnt matter, basically its the same process in every dry conition (we also grow varieties which crack really fast). There were some scientific papers which investigated the forces which the grains are suspended to when they are hit by the concave or by the drum/cylinder... and whats essential for the effective threshing. And by far the biggest reason for cracking was the rpm... when you ont have enough material in the combine. If you feed it enough the cracking wont happen, because the drum/cyliner accelerates the grains and the additional material cushions the forces again...

I mean you can see it live in ur sample... when you speed up, it gets better. Its the same with the dirt which comes over the sieves... at the end of the feil when you dont feed the combine anymore you get all the dirt in.

Dont you change the settings during the day when it gets hotter? More concave...less rmp.... and in the evening the other way round?

arcus I don't have trouble setting my d**n combine!!!! I simply said to the guy above to try 850+, I didn't say stop at exactly 850 ffs, and its where all this b.s. started. When I need help setting a lexion in a 10t/ha wheat crop in germany I'll call you. Until then I am more than ok.

I didnt wanna lecture you. Sorry for this impression. I dont doubt your abilities to set ur combime...

But the phenomen stays the same. No matter if Deere, Case, Lexion or NA, Australia or Europe...

And by the way, I agree with ur advise to try more than 850rmp...

Greeting Arcus
