Kirbyfarms,
I can share with you some experiences with the AJ. I use them in Oats, Barley, Wheat, Beans, Corn. First of all...you need to learn the 2 steps of this system. No. 1. Thrash the crop and then No. 2. Separate the crop. This may sound simple but your concaves and grates need to be in good shape to accomplish this. I have found that even in the light crop of "Oats" I can use more fan RPMs to clean the crop. One customer I harvested used his oats straight out of the bin for seeding. One thing for sure is that the drier the thrash the better you can get a clean sample. My thoughts for now. Hammer
