I am looking to do an upgrade to my 9760. I am haveing a hard time getting white caps out especially in Glenn wheat. Have talked to the guys an Precision farm parts, and Kucher at the farm shows. They all say they can take care of the problem. The guys at precision want me to put there bars in and put a speedup kit for the discharge beater. I have never heard anything on the speed up kit. Anyone done this? He also wanted me to put in a loewen ajustable precleaner. Kucher just wants me to put his bars in he said his concaves dont work in glenn wheat. Also was wondering about Loewen. Will I get the same results with loewen? Loewen is probably about half the price. Anyone have any of these setups? How well does it work?
