Combines What kind of seperator barsIJ

What concaves are you running, and how many coverplatesIJ What setting are concaves set at, and what speed is your rotorIJ How are you determining when you are running at full capacityIJ In down wheat, you will have some loss no matter what.

I have been running the stock concave set up, narrow wire for wheat and the wide wire spacing for corn with every other wire pulled out of the back cocave in corn. I've never have used cover plates. Will they help get the crop threshed quicker which in turn gives more time for separationIJ I've tried all the other things in the trouble shooting chart recommends including lower rotor speeds.

Hi Red. Well What I say is only my opinion, and my climate and yeild may be different than yours. But, in wheat, if your tank sample looks nice and clean and seive loss is acceptable but you have rotor loss, then sometimes it could be as simple as cutting a little higher. But dont cut too high, I like some straw for the grain to rub against for threshing. Of course like you said, your wheat unfortunatly went down. One thing you might try is to run the machine at a specific rotor rpm drop and see if it helps. I would try letting the rotor rpm drop down about 50 to 60 rpm from the empty speed when you are cutting. Just watch the rotor tach and run the combine from it. that way you will have a steady load on the machine and can set it accordingly. The real only purpose of coverplates is to keep the grain from falling through the concaves too soon. If it falls through before it is finished threshing, then you will have excessive tailings and probably more white caps in the tank than you would like. On my machine in heavy 130 -150 bpa wheat, I like to run the whole first concave covered and the first half of the second. This way the grain has a chance to thresh completely and can then seperate more easily. I've never ran disrupters in wheat either. If you have the keystock grates you should have plenty room for seperation and should'nt need the disruptors soaking up power. In fact, in downed wheat you may wish to remove the smooth bean bars and reinstall your rasp bars. I'm not very well versed at the corn thing, so hopefully some else will post more on it. Also, there have been many post further down the page you might look at. But so far it sounds like you are on the right track. farm kid 2 has alot of experience with corn. look for some of his previous posts.

You must remove all of the seperater bars and replace all of the bars from the concave back with rice spike bars. This is in the directions for the installation of the Disrupters. The rice spike bar tooth will swing within 1_8 of an inch from the disrupter lugs and will cut corn shuck up to power.The seperater bars are in stalled on the specility rotors to keep the corn shucks in the seperating section to unload the full corn shucks. This also retards the green stem bean straw as well. Something that you don't want to do. With the Disrupter system installed corectly you will cut up the bean straw and also cut up the corn shucks that carry the corn out. The reason that Case put my Disrupters in their parts book was for the rotor lose in corn on Specility rotors. What they didnot do was inform their parts personal and service tecks of how they work. We have over 10,000 sets of The Disrupter in service in the past seven years and they work realy well. Ask some of your neighbors or give us a call at Estes Mfg. Co. 1-800-235-4461 Ask for Don.

Hi Don. I read your instructions for the disruptors on your site. Have you or any of you customers that you know of ever ran disruptors in any kind of grass seed strawIJ If so, what were the results, and do you think Red Greene needs to run them in downed wheatIJ

I think I would shy away from the Disruptors in grass. They can absorb a lot of power if the crop is tough, transferring that force into the grate section of the cage. The grates are not supported by a pipe like the concaves are. There have been cases where the cage split under the additional load. This would be more likely if the cage is worn thin, or the rotor speed is very slow, allowing large amounts of torque to be generated.

Ok, that makes sense. Even without the disruptors, I've heard of people splitting the cage in tough grass. The newer rotors are thick enough now so they dont implode much anymore, so I guess the cage would be next inline to destroy. After you mentioned about the standard rotor not having kickers, I went out to our old standard rotor and we used to have what they call bar extentions on it. Kind of a standard rotor kicker. Can you tell me what the difference is between the plain angle kickers and the bean angle kickers isIJ

OK, you got me curious about the Standard rotor, so I looked at a 2188 parts manual and it did not show the "Rear Bar Extensions", so then I looked at a 1680 manual, and it did show them. I had never heard of them, but my guess is that they are no longer recommended. As for the kickers on a Specialty, sometimes they call them "Angle Kickers" and sometimes they call them "Helical Kickers", but I think they always have the same shapeIJ There seems to be a Chrome version for the Custom Cutter package. That's all I know, maybe there is more to the storyIJ

Ok, now I wonder, you have done a lot of study, what would you think if someone was to put eight stripper bars on a standard rotorIJ

I don't think there would be very many conditions where 8 separator bars would help the standard rotor. I think the available combinations of grates and bars (smooth and green maize) give a person plenty of options. I would concentrate on the threshing part of the rotor. The goal is to find the combination that threshes adequately in all conditions, but does not over thresh in any conditions. For different crops and different moisture levels, that is not an easy task. For example, when we ran the St. John rotor with a modifed Specialty in wheat, the Specialty would loose less grain during the heat of the day, but the St. John rotor would cut circles around the specialty when the sun went down and the straw got tough. In fact, as the crop got tough you could see the monitor loss actully drop off for the St. John rotor and the monitor loss go up for the Specialty. For us, the slightly higher losses during the day are a good compromise so that we can greatly minimize the losses at night, which is when we run a lot. The down side is that with the ability to over-thresh comes the responsibilty to make adjustments during the day (if you want max performance).
