Combines Gorden Helical Concaves

I talked to a guy at Straub International who had several sets running. All of them had all 3 helical concaves installed and were running Gorden bars on Specialty rotors. He said that threshing was improved and that the owners were happy.

I doubt that you will hear anyone complain about any of Marvin's products...all top of the line and well researched before offered on the market. at least that's been my experience...I have been trying to add something from his offering every year or two.
