Combines Should I buy serrated or flat feeder house chain slatsIJIJ

Dink; I can only go by the comments of previous guys in the forum who say the serrated slats may wrap, or carry around the crop mat in the feederhouse. I've heard of chains with serrated slats on every other slat too as a hedge against wrapping. I have never used serrated slats in a corn soybean operation. I don't know what crops you do, so that would make a difference as well. The upper drive sprockets may well be shot if the chain needs replacement. Good time to change the upper bearings on that shaft too. I always figure, do it, or wish you had done it. Good luck.

We've run both and can't tell much difference in feeding. The serrated is a lot harder on the bottom of the feederhouse if you let it get too loose. We've switched back to smooth. By the way, the Black Ace rollers will pay for themselves pretty quickly. We also run the front of the chain in the highest position so that the chain is looser. That setting with rollers will make a chain last a very long time.

The new style serrated are good for all crops as the all new combines come with a rolled serration in the slat not cut like the old style. The older style serrated slats were for small grains only and were too aggressive on corn_soybeans as a result would crack_damage the grain.

I think you are better off with the serrated. loewen is a good aftermarket chain, and you can choose either domestic or import roller chain. loewen has the rolled serrations also as mentioned in another response, and had them on market many years before CASEIHC.
