cylinder bars 8820

these are 3/8 in the center, what are they new,do I need to change them? is this why I pluged the combine 3-4 times last year

IT all depends on what cylinder bars you have. 3/8s could be shot or could be fine. You can tell by looking at how even they are side to side the edges wear little compared to the center. As for your plugging the cylinder. That could be caused by many things: feeder house drum set wrong for the crop/header your running, cylinder speed wrong for the crop conditions, if your using a grain platform the auger extensions could be set wrong for a JD 8820 as most where used on smaller machines.

The long and short we need a little more information to tell you if the cylinder bars are the reason you had cylinder plugging. Crop and conditions you where harvesting in is one thing? What settings you where running at when harvesting? Also what type of cylinder bars you have, factory JD bars or after market ones???

check your concave/cylinder clearance on each side, your owners manual will tell you.

Where did it plug? If you got it to plug in the cylinder how did it make it through the feeder house? Green stem soybeans will plug a jd feeder house pretty easy.

I run beans&corn what bars do I need?? when it plugs the belts slip, it doesn't kill the engine, 25' head in beans 20% green weeds and it will plug

Do you have the feeder drum stops flipped for beans??? They have to be turned from corn to beans. IN corn the allow the drum to float up and over ears of corn. In soybeans or other small grains you set them down so the feeder house chains cleans the bottom better and you will plug the front of the feeder house before the cylinder. This way you can use the reverser to back out any slugs.

Also on your 25 foot header look at the cross auger flighting and see if it quits just inside the width of the feeder house. IF the header was sold new on a smaller machine then they would have left the flighting long for those machines. You had some extensions that where bolted on and on others you had to actually cut the flighting and spot welds off to get the correct width. Then there where more feeder finger holes that had covers on them that you installed more so the material would feed across the entire width of the feeder house.

When your machine plugs doe the over beater plug first??? IF it is doing that then you will need more cylinder speed to speed the over beater up so it can handle the extra material.

Also 20% green weeds is pushing the limit of what you can expect the machine to handle. That is why soybeans where usually harvested after hard killing frost in the past. It has just been with the RR beans that we have supper clean fields that you can harvest so soon. SO even with everything working right you may have to slow down a lot for the green stuff to go through the machine.
