We have a used 8570 1992, was used in Tiwn Falls Id. by a farmer-custom cutter. Thay say they cut about ever thing there is to cut with it and the in side of it look like it to. The man said he came up with the round front feed beater, this one is home made 2 rounded peasses bolted together with angle iron to fit over the sqwear parts with 4 rows of bolt sticking out with there heads cut off. My first quition is about the separating grate. This one has some of the rods bent and polled in from the side. How do I tell if it is wern outIJ Is there any better thing that work for wheat, barly and safflowerIJ I have meny more quition but no time right now. Thanks swtvid
