Hi there.... I tried a poly slat chain from Harvest services in Sask. Canada and I returned it about half way through soy harvest...I could not stand it. All it did was wrap and not feed well at all. The slats were bringing material back to the front and all it did was ball up and make a mess. The rotors and beater sound like a good idea. Did you replace the beater grate tooIJ I found that to be a really weak point in the TR86 that I owned. Could you put the link up for me on the rotors and beater or was there not oneIJ thanks lA.
