help gleaner E in corn

I always set my chaffer and sieve by eye (if memory serves me right, I think the chaffer is 3/8"-1/2" and the sieve is 1/4"-3/8" for starters), on the air run as much as you can without blowing grain out the back.  To set the cylinder, start at about 3/4" and if the cobs aren't coming out in 1 piece generally in the rear, then open the cylinder a little more until you get whole cobs.  With the whole cob, unlike what the manual says to quarter the cob, you have the ability to pass the entire cob out over the straw walkers.  If you break the cob like the manual says to do, then the cob pieces go through the walkers and add more load to the chaffer to clean.  Cylinder speed if I remember right should be about midway on the variable for  starters on low speed sprocket.  Then speed the cylinder up until you start cracking corn, then slow it down a little to stop cracking.

cob size and condition will affect things too. break a ear in half and look at the cob.   my corn went through good in my F but did some poor corn with tiny cobs for a guy once and completly clogged the chaffer and sieve with cob pieces. not fun...   

i dont think MACK meant 1/4" cylinder thats bean settings

If you don't have walker screens,don't run whole cobs(3/4 clearance) or your walkers will be plugged with cobs.Don't think they made screens for E's so that's why you grind the cob and crank the air....like Mack said.
My A2 had narrow woven wire fence tied to walkers with bailing wire when I got it and that worked well.Settings should be in manual.Corn might be called maize.

Thanks for the replys guys. I never thought to look for "maize" in the manual! I have the air wide open. clearance at 1/2". Air 3/4 open. Not sure what I have for cylinder speed. 80% of cobs are coming out the back in one piece. But I have half of the kernels are cracked or broken in the bin. How can I not crack the kernels?

Is the corn dry? Sounds like it may be. Does it shell easy? Take a cob and toss it 10 feet into the corn head. Does it splash and send lots of kernels flying? If it does, first slow the cylinder down to 400 (get a photo tach or a hand held rubber tipped tach). Try it out then if you want to get most or all of the cobs out whole open the cylinder clearance a little at a time. Oh and remove a concave bar(s) according to the manual if still getting cracked corn.

corn under 18,2 concave would be all you need. Keep slowing cylinder til you start leaving kernels on cob then go back up a little.

You must change the driven sprocket on the cylinder from oats to corn. Even tho you slowed down the variable belt drive, it will still be waaaaaay too fast for corn.

ug.......... winter

Yes, 1/4 will work on corn. Have took a lot of Gleaner to field set at 1/4. Yes it will bust the cob, but open the air and blow the cob out the back. Plus that corn bore winters in that cob and you have destroyed his winter home.   MACK

I have the 21 tooth sprocket. Which sprocket do I switch out with the cylinder one or do I have to buy a 35T one? Which concaves should I remove?

Just amazing! I never ran a combine. Dad always set the old 66's when doing oats, wheat, or grass seeds. We never had a combine to do shelled corn. So I listen and read and understand there is some adjustments, some art and some difference in the corn being shelled. I was watching a big green machine combine corn the other night while I was deer hunting near by. Not sure what kind of machine it was? Wasnt a galvanized machine!

separator won't separate worth crap at half throttle

If you don't have a 35 or 44 tooth sprocket, leave it in the shed or quit complaining about cracked corn. If the combine isn't properly equipped it can't work right.
