1660 Axial Flow Tough Threshing

Tough wet soybean stems real make the combine struggle this year. Never had a issue like this before. Would installing new rub bars and concaves help material to flow through easier?
 
If you have a specialty rotor, I've had good luck putting the notched rasp bars on rear of rotor instead of straight bars. Also helps to swap out keystock grates for slotted grates on rotor if they are really tuff. On the 1640 we had with standard rotor, we put notched seperator bars on it. It helped a little but it still didn't like it.
 
Hey Rod!! 3 things will drive a man to suicide: Bad wife, bad baler & bad combine. When I retired the J.I. Case 1665 for a 1460, I almost got there, but wised up & swapped for a Deere before I did myself in. Tough soys were a real challenge. I even installed The Disrupter Kit. Look into it. Actually shoved a rear grate right out the back.
 
Hi John, I have run a axial flows for 16 years now and have had very good service from them. I know if I am more patient this crop will harvest better in a week but dang it is hard to wait when bean moisture is correct.
 
Way back when we went from 915 conventional to a 1460 and suddenly couldn't combine after dark we mainly put in the Estes disruptors and new finger bars and moved the stationary vanes to fast (have to be returned to slow for corn--a lot of work ). Worked even better on the specialty rotor. And yes, sometimes wrapping would loosen a rear grate.
 
Rod, what rotor do you have? Standard or specialty? Are you running on the high side of the rotor or still on the low side? On our old 1640 with standard rotor in tough beans with green stems I had to run the rotor at 750rpm in the high side, and that helped but it was still hard at times. The others gave some good tips also.
 
This x1000. Putting an auger style front end on the rotor will make all the difference in the world in soybeans, especially tough green stem beans. There are several different styles out there. Like is perhaps the easiest to install as you can do it with rotor still in the combine. Ive had experience with the Loewen and Stewert Steel ones. Theyre excellent but require rotor to come out to install.

Also make sure all straight bars are off back of the rotor and speed the vains over the rear of the rotor to the fast position. Run your rotor at 750-800.

The problem with green stem beans is that they want to rope up as they go through the rotor.

Also if you dont want to put an AFX style front end on the rotor, make sure your elephant ears are in excellent shape with sharp square edges to grab the beans. Ears with rounded edges just compound the problem.
 
I put a Kile kit on the front of the specialty rotor on my 1660. Gained about 1/2 mph in green stem beans. The downside is it cracks corn worse than Jenny now. lol
 
90 degrees a stiff breeze and things will go alot better. We were fighting tough green stems with a 9400 deere last Thursday/Friday. Warmed up and got windy Saturday thru today and we've been flying, will finish tomorrow. Problem is beans are now testing in the 8's.
 

If the pods are dry and easy to open but the plants still have green stems and leaves you can open the concaves more.
