Yes the Ten series Concave is a 13 bar while the other is a 14 bar. First thing I would try is to get a kit to speed up the fan speed. You can get this at your local dealer. We run 1400 to 1500 RPM when cutting soybeans. Make sure the concave is set between 0-4. This will help a bunch. And maybe in the off season upgrade to a 13 bar concave. We installed the new 13 bar concave this year and it has really helped the machine keep clean beans in the tank.
