Combines how to keep corn cobs wholeIJ

How many impeller blades are on your standard rotorIJ Its amazing what happens in just that short distance between the feederhouse and the concaves. If you want to find out where your problem starts, do a Quick kill to shut the machine down full and take a look inside. Thats the most informative diagnostic procedure you can do. The notched bars over the grates may make some difference alright, but it may not be the difference you are looking for. You say you have large wire concaves and still took everyother wire out. Have you tried it with the wire back inIJ The problem may not be the size of the cobs, but it may be that you're letting the pieces fall through too easy. As for the short seive, how many fingers are installed on the sawbackIJ If you only have the short fingers, think about installing the long ones as well. It will help distribute the material onto the seive more evenly. The stock paddle style fan, if thats what you have, seems to like to have the material contact the seives a little further back. Aso make sure the rubber air dams on the back of the seives are in place.

Old Pokey I just have to impeller blades on the front. As to the wires in the concaves if I reinstall them I get way to much rotor loss. I do have the old style fan. thanx for the ideas Brad NC. IN.

I have been down this road also. taking out front straight rasp bars helps,keep rotor speed down as low as possible. am running large wire concaves with all wires in. just for the record,I run green maize bars and disrupter plugs.try keeping your concaves as tight as you can,this keeps the cobs from tumbling end wise in the rotor,if you have a rock trap check the sprocket,i believe mine has 30 teeth.I have a lot better luck pushing the rotor full,running a 1660 with 6 row head in good corn 4 mph+,then open sieves wider ,you can get by opening because the full rotor and other adjustments keep the cobs much more intact,good luck

pinch point if off or rotor is not level to concaves check these things out. open her up and slow it down no more than your putting in it shouldn't have a problem.

2 more things make sure your drum in the feeder house is in the highast positon and also straw chopper in slow speed with the knives in least amount of chop and may be your vanes need to set to run the corn through faster. I would try about 1 to 2 on concave roter about 350 and hope it works. Remember some corn has rubery cobs.Maybe diferent varity will work beter. Hope this helps.

I know this is not causing the problems with the small cobs but I would recommend changing your paddle fan to the newer style. A couple of good reasons...Much better air flow at a much more even flow across the sieves, but the main reason is the age of the fan. Unless you have replaced it recently it's probable showing it's age and could very well start to fatigue and break up causing major damage. I've never heard anyone wish they had not done the fan update to a 1680 after they had done it.

I have. Several people have wished they would have stayed with the paddle fan.

What's up with this site this morningIJ I can't post. If I click on AFS Reader 2188 at the top, I get this response by Old Pokey.

thanx for everyone's replies on the subject I'm still not quite sure what to do cause I've tried everything that was mentioned, except zeroing the concaves, I've heard of it but never q uite understood how to do it. thanx for the help Brad NC. IN.
