Combines cleaning out cobs

[tbran]

Yes, refer over to your left 'Hyper mods' for picture. 'Assume' you have a R40-70 low wire grate at 1_2" spacing P3. Removing every other wire will eliminate your problem. IF you have problem with wheat not being threshed simply inset concacve filler strip or strips to gain agressiveness. Early models were not as easy as late models. I torched my sep grate wires, the one on the left bottom. The thresher grate separates in the middle and the lower wires come up and the upper ones down. Some had a plate spot welded in place to hold the upper ones in which had to be despotted. later grate wire retainers were bolted in w_ 1_4" bolts.

I have a R50 1989 or 1990. I guess this would have been good info in original note. The concave strips are from dealerIJIJIJ Thanks for your help, the cobs are a pain. I just do not want to hurt combine preformance. Still looks like this will put a lot more trash on shoe. looks like have a good winter day job to remove bars, can concave strips be installed with rotor in cageIJIJIJ

Here is some more info. I run a 20 foot flex head and a 6 row 30 corn head.

Remember the old Nike commercials - "Just do it!"IJ Well, that applies to removing concave wires. We had a '90 R50 as well and were skeptical about removing those wires, but NEVER regretted it after finally taking the plunge. You will find a noticeable improvement in rotor loss in corn due to the concaves not being plugged with cobs. We have never noticed increased loads on shoe in small grains either. The concave filler strips that tbran mentioned are available from AGCO. They can be installed by opening the rock door. It goes faster if you can convince your mother-in-law to squeeze into the engine compartmant and install nuts while you hold the strips in place from below. Don't know how long you have been reading this board, but I haven't seen anyone yet who has reinstalled the concave wires after taking them out. That should tell you something. Just do it!

Tl , I passs on a bit of important information, NEVER use Mother and law and nuts in the same sentence please,.

That was great!!! I fell off my chair laughing!!

For seven years I have used three filler strips in corn and beans, and have seen no reason to take them out, as bin sample is better and losses reduced. Anyone done testing on filler strips for negatives for using themIJ

I'm terribly sorry tbran. I should have known that would trigger flashbacks for you - a common symptom of post-traumatic stress syndrom. lOl! Tom l.

 

[Dave]

Well my MIl would never fit in that spot. I may be able to stuff my wife ( only help other than the cats) in there and let her help. It sounds like I need to remove the wires. Should I install filler strips at that time or wait to see if I have problemsIJIJ Would the problems be only in wheat, or corn and beans alsoIJIJIJ

I'd wait to see if you have any problems. I forgot to mention that we have never had a need for filler strips even after removing wires. But somehow we aquired a set of them for whatever reason. I'd say you definately don't want them in there for corn - the more open you can keep your concave, the better. Shouldn't need them for beans either. Might need them for harder threshing wheat varieties. If you do find a need for them, add just two or so at first and try it - add one more at a time until you find the sweet spot. The more separation that you can accomplish at the concave, the better and the filler strips prevent separation. Tom langan Actually, you can probably get them mounted by yourself. The bolts are welded right to the filler strips so all you need to do is set them into the concave then climb up and put the nuts and washers on.
