L2 concave 9 bar vs 7 bar

Does anybody have any experience with the aftermarket 9 bar concave vs the original 7 bar? are the bars closer together or does the open section extend further back?  Curious on the performance of the 9 bar in wheat.  Thanks Kevin

	I put the 9 bar Lowen in my L3 several years ago with new bars, got them from Abiline Machine IIRC,,,I think the 2 extra bars extended further back than a 7 bar. but man! what a difference!!,, it was a total different machine!, I run 1/8"-1/4" clearance, ~600-700 cylinder RPM, done excellent job of thrashing with little to no cracking. I have not run this in corn, the concave wires are closer togrther, so not sure how well it would work in corn, I do believe Lowen makes a different concave for a corn/wheat application,,, but I'm not sure about this... sunnybrook is what Gleaner carried,, and they had a 9 bar also,,, I think..... If your only doing wheat,, I don't think you can go wrong with the 9 bar... Edited by Michael V (NM) - 01 Dec 2020 at 10:18pm

	Thanks for the info Michael, I found out that Sunnybrook has them in stock, so I think I will give it a try.

	Any updates from anyone else on the 9 bar? Always been OEM style 7 bar here, about to pull the trigger on a 9 bar for a customer and wanted to get some more input,figured I'd add to this thread rather than start another. Luckily he is almost all small grain with it, so I'm going to say he "should" be happy, just double checking. :) Edited by GM Guy - 15 Jun 2021 at 7:15pm
	Gleaner: the properly engineered and built combine. If you need parts for your Gleaner, we are parting out A's through L2's, so we may be able to help.

	Here’s the AGCO (Sunnybrook) website, that discusses this concave. It reads that two spacing are offered 1 & 2”, so grower will need to decide which spacing is best for their conditions?? “Gleaner Models L & M Conventional: All concaves manufactured for these models are heavier than original equipment. Two extra threshing bars have been added to increase threshing and separating ability. In addition they are precision line-bored to ensure a perfect circle and fit, and have four removable filler plates. Two wire spacings are offered. The 1” spacing is more common since the 2” spacing is effective only in cereal grains with large amounts of straw.”https://www.agcopartsandservice.com/content/dam/agcopartsandservice/NA/Combine_components_reference.pdf/_jcr_content/renditions/original
