Farmerboy72 Posted September 22 Share Posted September 22 Does anyone here have any experience with the Gordon sieve system? My new to me 2344 has this in and I am not sure how I set my concaves for corn and soy beans. I did run a round bar concave for corn and regular ones for beans in my 1644. Would my setting be similar, or is it completely different? Thanks for any help Quote Link to comment Share on other sites More sharing options...
brahamfireman Posted September 22 Share Posted September 22 Are the Gordon seive the ones where the top sieve is non adjustable? Just angled holes? Setting the concave is a separate thing than the lower cleaning system. What heads are you running? Approx bpa of each crop, crop condition, all effect concave settings. The sieves are for separating grain from material after the rotor has done its job. A properly set concave and rotor will make a machine handle lots of grain. A properly adjusted cleaning system will give a clean sample. Give us a few more bits of info and we'll be able to get you a very nice grain tank sample.

Yes it is where the top seive is non-adjustable. I understand some of that part. I more in setting the concaves properly. Running a caseih1020--20ft head in 50-70 bushel per acre soybeans. Ideally 13% moisture, usually drier than that. Running a six row Drago corn head in 180-250 bushels per acre corn. Not afraid to run 20+ % moisture corn if I have to. If more Info is needed, let me know. I will try to provide. Thank you Quote Link to comment Share on other sites More sharing options...
FarmerFixEmUp Posted September 22 Share Posted September 22 Is this the same as an air foil chaffer? I have one for my New Holland combine but never used it yet. A neighbor had one in his 6620 and thought it was the greatest. You need all the fan speed you can get. Quote Link to comment Share on other sites More sharing options...

With Gordon the top seive is angled with different size holes for the grain to drop thru, the bottom seive is set open (11/16 I believe). Then there are special raspbars put on the rotor to help with the threshing. This where I need help to possibly get an idea of settings before I start.

Large wire concave with every other wire removed, cover plates on first concave section. 400 rotor rpm, fan at 1100 if possible, some max out at 1050ish. Transport vanes full advance. Set concave opening about 3ish on side chart, if your cracking lots of beans when they get dry, start slowing rotor down, no lower than 350. If they're still cracking open concave slightly. Once they get way dry they crack easy. Open bottom sieve just enough to get beans through it. Quote Link to comment Share on other sites More sharing options...

Open rotor 5-7, then keep closing until you start breaking cobs, then open slightly. You want whole cobs with just a bit of corn on the tip. Fan 1050-1100. Lower sieve 3/4 to wide open. 250 bpa corn is gunna be alot for a 44 size machine. My rotor speeds might need to be adjusted higher, I'm used to the bigger 88 series machines with bigger rotor.

If the residue wasn’t even on the shoe, it didn’t work at all I didn’t think. We had one many years ago. Quote Link to comment Share on other sites More sharing options...
Drysleeves Posted September 23 Share Posted September 23 Only aftermarket sieve I've run is the Peterson chaffer. I think it may have been called "air foil" for a time. Lots of fan speed was encouraged beyond book specs with one of them installed in an Axial Flow. As I can recall it was a run the fan wide open sort of a deal.

Farmerboy72 Posted September 23 Author Share Posted September 23 1 hour ago, brahamfireman said: Large wire concaves, Sounds like you have experience with this system. A lot of helpful info, thanks. When I had the 1644, we used a round bar concave in the second, and then the third concave had every other wire removed. That should work for corn shouldn't it? Or would it be better to have round bar in the third also? I will need to get a cover for the first concave when we run beans. That unfortunately didn't come with the combine. Another question, is there a set of concaves that would work for both corn and beans? To save changing them between crops. Quote Link to comment Share on other sites More sharing options...

Another question, is there a set of concaves that would work for both corn and beans? To save changing them between crops. I leave the large wires with every other wire removed in for both. That's why I run cover plates on the first concave. Without them, the bean pods fall through way too fast and don't get thrashed out. You want beans to stay in the concaves slightly longer to help thrash out the tougher pods, that's what the cover plats do. With corn you want it out as fast as possible to maximize capacity. with every other wire removed you should have no problem getting the corn off the cob, but still have plenty of capacity to get 200+ through the machine. I play with the fan a bit as the day goes on, generally turn it down until pods start showing up in tank, then crank it up. That's the beauty of the air foil on top, nothing to adjust, just let the fan do the work. Trick is you need to have the rotor and concave doing their jobs properly first. Too much MOG will frustrate a guy quick with an air foil. Need to keep the chaff going out the back of the rotor and not onto the cleaning system.

Michigan No Till Posted September 23 Share Posted September 23 Rotor and concaves doing their jobs the first time through and chaffer set right to allow grain to fall through and just enough fan speed to get rid of MOG, bottom sieve in theory can be stood straight up, more air flow up to the chaffer!??? 1 Quote Link to comment Share on other sites More sharing options...
Drysleeves Posted September 23 Share Posted September 23 Yes the shoe sieve needs to be as open as possible to allow sufficient air when harvesting corn. Quote Link to comment Share on other sites More sharing options...
IHC_1470 Posted September 23 Share Posted September 23 I thought the Gorden system had different screens you could change out on the frame? The Peterson system just has the fixed holes. I have seen pictures of the Peterson idea that was adjustable more like a regular sieve. I would think the idea is similar with either system where you are using the fan to provide the cleaning. The advantage of the Gorden system is you can change hole sizes on the screens. I have only ever used the Peterson system. Quote Link to comment Share on other sites More sharing options...
Michigan No Till Posted September 23 Share Posted September 23 Beans too @Drysleeves. I will try this and report. Quote Link to comment Share on other sites More sharing options...
Drysleeves Posted September 23 Share Posted September 23 Tighter shoe setting for beans but chaffer can be left alone most of the time. Quote Link to comment Share on other sites More sharing options...
Dirt_Floor_Poor Posted September 23 Share Posted September 23 Around here (corn/bean country) on the Deere machines everybody runs round bars for both crops. Does that not work on the axial flow? It’s common to run corn and beans in the same day with the same machine and nobody is changing concaves in between. Quote Link to comment Share on other sites More sharing options...
Michigan No Till Posted September 23 Share Posted September 23 Large wire concaves in mine for corn and beans. One cover plate in the front module to keep the bean pods from dropping through. Have a second cover plate, but have never needed to use it. Quote Link to comment Share on other sites More sharing options...

With my old setup I changed concaves between crops. Round bar for corn and then back to the regular. I would like to know if I can use round bar for both crops. If I have to install coverplates, that wouldn't be all bad. Quote Link to comment Share on other sites More sharing options...

What are you calling "regular" concaves??? I've said it 3 times now, just use the large wires with cover plates for beans, no plates for corn. Changing concaves sucks. 2 Quote Link to comment Share on other sites More sharing options...

I've said it 3 times now, just use the large wires with cover plates for beans, no plates for corn. Changing concaves sucks. This is a pic of the roundbar we put in for hi moisture corn and corn. If you look behind it is what you call large wire with every other wire removed that goes in for corn also. What I call regular is most probably what your calling large wire. I don't run any small grain that would require fine/small wire. Sorry for the misunderstanding. when running hi moisture, we tend to have somewhat green fodder, the roundbar helps tremendously. If I can work just using roundbar for both crops is what I am looking at. I didn't know if it makes a difference with the Gordon rasp bars.
