Combines Chaff buildup on left side of concave

[dslman]

make sure the hose on the center back cage sweep tine is a steel braided hydraulic hose. have seen some guys use heater hose and that just doesn't do the job, not rigid enough for most conditions. also be sure the hose is not to long. it needs to be just long enough that it comes across the center support and flicks both directions as it crosses over. i've seen a few that were to long and the hose would just bend as the tine crossed over the support and wouldn't flick the material off of it. just a couple of things to check. good luck, dslman

Install solid plate over cage material near supports to provide area that straw can not come threw cage. We needed to do this to prevent cage sweep pluging in spring wheat. We still have the covers on when cage sweeps are removed. We also build a tin wall up and half way around cage when sweep is removed. That kind of duplicates the wall the P3s have. Good luck

Can I use a cage cover or do I have to fab a pieceIJ Either way I don't have any cage covers so I will have to make a cover. Actually,I thought about doing just what you suggested but wasn't sure how that would affect things. It seems that the bean straw is more brittle this year. You would have thought just the opposite with all the rain we got here in Eastern Ia. Thanks, Pete

I did use hydraulic hose and in tried various lengths on the sweep that goes across the center support. I think Dan is on to something with that cover. It seems to me that the material that normally would stay inside the cage is breaking up this year and coming through the cage. Thanks, Pete

Beings your still using your cage sweep you could likely fabricate a couple pieces about 3" wide. You will likely not have enough helical bolts sticking threw in that area so I think I would just stitch weld the iron in. I'm quite positive this will cure your problem and you won't need to remove for anything. Good luck

Pete, Sorry to here about your trouble.I never did pull my rotor.I put new chrome loewen thresher bars on and did the chaffer mod.With my N-5 we have been running 3.5mph with a 320 flex w_hose mod.I had some bad growling at first until I sped it up to625 rpm on the rotor.The stems are plenty green in places but we're only dealing with 40bpa.Has worked awesome so far.Is the N-6 cage different then the N-5IJP.S. I am not running my cage sweeps.

I beleive the N5 has parts of the cage area blanked off but the diameter of the cage and rotor are the same. Glad to hear things are going well for you with your N5. I would really encourage you to modify to rotor before next fall it makes a world of difference in corn. The nice thing about these mods is they can be done in stages as time and money allows. It also allows you to get to know the function of your machine which helps in making adjustment to maximize capacity and grain quality. The biggest thing I noticed about the rotor mod was that I was no longer grinding the cobs and my sample quality increased dramatically. Just remeber to install some type of disruption in the belly of the separtor to keep the rotor loss down. I have always had to run my cage sweep, even after I hyperized my rotor and cage. I am not sure why I need to run it and others get along just fine without it. I did find my cage covers in the corner of the shop and installed one above the left concave support bracket. Pete

Dan, I did find my cage covers in the corner of the shop and installed one above the left concave support bracket. I had to modify the cover to get it to fit as I have channel helicals in that area. The more I sat and analyzed what was happening I became more convinced that a cover in that area is what's needed. In some situations I beleive the hydraulic hose will work, but with the ammount of material coming through the cage in that area the hose could not keep up. Thanks again, Pete

Pete I think you will have a high chance of success with the cage covers. I have had cage sweep plugging also in the past. It usually starts at the left or right concave pivot arm area. I have taken cage covers and reduced their size to a fourth or third of original size in those two areas. My goal is to shield the concave arms but not block anymore cage area than necessary. I started beans three days ago. As soon as I got my Hyperized N6 up to speed the cage sweep plugged. I put in my modified cage covers and haven't had any problems since. I'm running a 20' head in 50 to 55 bu beans at 4 to 4.5 mph. Hyperizing has made it a bean machine. Before if I pushed it past a turbo boost of 10, it would start to growl and load up getting totally constipated. Have a safe harvest! Gamaman

Where else did you cover the cageIJ I tend to get a buildup at the left rear of the separator and I was wondering if I should put a cover in one of those openings. I do have some 3_8" rod I can make some "hooks" and weld them to the last cage sweep to rake the material off the wall. It is cold and rainy here so I do have some shop time. Pete Hinrichsen
