What's the difference in capacity? I'm having problems with the 7720 with 224 in 70 bushel wheat. Can't get walker loss stopped. Would a 9500 be any different?

They were replaced about 300 hours ago. Factory oem bars and concave. They look really good. What do you think my field speed should be in 60-70 bushel wheat? I have a feeling my dad goes way too fast when he runs it.

Last year around here it was wet and alot of rainy days, we had to run on days when we shouldnt have been combining, and it was hard to keep the grain in the combine no matter how i set it or what speed i drove, i thought the harvesttrac was lying,maybe the weather played a part in your combine performance as much speed or settings.
