Yes, I put one in last year before wheat harvest in my 8820. Then I went to corn then milo and then some really green stem beans. The machine ate them and there was no plugging as in years past and no slugging the engine. They were not the highest yielding. It made my girl a beast in all crops. I really did not notice a real big increase in corn. But it does keep the corn from going through the bars. Call them and talk with them.
