You are really going to like your new TR-97 compared to a TR85. If you have that good of corn it will do okay with a 6-30 head, you should be able to run as fast as you want to with it. We had one with a 25' flex head and a 8-30 corn head. Our yeilds ran around 100-150 bpa. The grain tank holds around 240 bu. Good luck and have fun. Ilnh
The combine, with both heads ran in the low 60's. I feel we got a good deal, it's a one owner and very clean combine. The original owner traded to a tr-99, because he didn't want to jump to the cr's.
