We had trouble with the whitecaps in glenn wheat over several years. Finally, this year we didn't grow any glenn wheat just bec they were to dang tuff to harvest. The problem is not limited to green iron but also cih's. We found the best thing to do is to speed up the rotor wide open, close the concave all the way and fan at about 1000 or 1100 if I remember right. 3 rows of grate covers and 3 concave plates on 9760's. While it was not perfect, it was the best we could get without throwing out the back.
I have been very happy with the PF concaves. I ran the first concave Extra Narrow, then the rest Narrow and have been very happy with the cleaning of our wheat. For next year I will also add the PF elements.
Has anyone ran a comparison between the PF parts elements and/or Kuchar elements and/or the loewen elements? Just courious to see if their is a difference between when going from the 15 elements (loewen and kuchar) to the 9 elements with PF parts.
