Mid-Missouri | Dude, you have to go to the field with a leveled concave. Not lecturing but that is combine 101 basics that is a very important aspect of the combine.
I had a variety or two that had spongy cob, 18% and under, 200+, 740 with 8 row. It would break cobs instead of roll the cob clean. Ended up with soybean keystock APS, roundbar main, 400 + rpm, 27mm and 360 on rotors. At these settings, loss became acceptable, clean sample, could go 6 mph if I wanted to.
I stress that people windrow the crop out of the chopper to get a true picture of how the threshing is being done. It can easily point out issues. When it goes through the chopper, you don't know if it is a threshing or seperator issue, etc...
Metric Allen wrenches work well to help level the concave via the inspection holes.I think 7mm toward front and 4 in the back. Leveling can take time but should only be a seldom issue.
