John Deere Combine Settings for a Successful Soybean Harvest 

Thanks for the knowledge

Hi Marion I'm from Australia, and we run 5 of the sts's for wheat, barley, canola and lupins. I've been using John Deere's since the 955 model The one thing that I never hear people talk about is the grain loss sensor for the rotor. The loss monitor in the cab has the rotor icon, as a walker (50,60,and 70 series) but the rotor sensor doesn't measure grain loss. It tells you that you are getting grain separation at the rear of rotor (separator) meaning that if the monitor indicator , starts moving up, (usually cold conditions) then we either have to close the concave clearance, or speed the rotor, in order to get more grain separating at the front (in the concaves) The monitor is a carry over from the walker machines and is a false indicator to the operator. All of my new operators slow the ground speed, because the grain loss monitor shows an average of the chaffer and the rotor. I tell my operators to only look at chaffer loss when deciding to reduce ground speed. In general, the chaffer is the limiting factor for wheat and barley, but we can still fill the box in under 10 minutes providing ground speed hasn't been compromised. We run 40ft draper fronts and we find that running the choppers at full speed (knives lowered) will give us extra capacity as well. We run the concave gap around 30 and repeat more if we have to, as this is more efficient than trying to knock all the grain out in the first thresh. Top chaffer opened higher than recommended and sieve, lower than recommended (around 3 for wheat) We also run helical concaves for strength and aggressiveness, so that we can open it up more. Thanks for the video, I will come visit you when I get over there. As a point of interest, I was the demonstration consultant for JD in our area as well as sales/AMS . (Contractor/repair/modify now)

That green looks good on ya, Marion!

Thats all well and good on a rotor machine but changeing concaves on an axial to switch corn and beans is a hell of a job.

Marion, for wheat, we have a small operation and about 60 acres. what about using the inserts in the first two concaves meaning the ones you refer to as venention blinds. with our low acreage of wheat i dont feel buying wire concaves is realistic so what would you recommend for use with the bar concaves. can those filler plates that you found in kansas be used on the back of the round bar concaves. maybe use one of those and then several inserts??? just wondering your thoughts. thx

Great video, the longer ones are better! Iv been doing a few kill stops on our s680 and can’t get the rotor to stop very quickly, I’m going by what the manual says, how do you do it?

👍🏻

I have soybeans coming out of the back of a JD 9870. You can hear them hitting the window of the grain cart tractor. We have tried a lot of different settings with minimal success. Any suggestions?

how do i adjunk for cornô

Marion, 50 years of harvesting?? You start harvesting when you were 12 or so?
