Case combines

[biglentil]

I think the big tube rotor is more consistent in canola, small tube you are forever changing settings throught the day. likely overloading sieves with overthrashed material, swaths are probably shattering into dust. i found keeping the bottom open more and closing the top helps, slow the feder house down to match travel speed, almost completley close the presieve, slow the rotor right down, fan speed at least 650 and slow down. If you get too much falling thru the top, you could be getting MOG and seed falling into the fan slowing air flow. get a drop pan to test for loss out back.

Slow down! Have you seen the forecast and looked at the calendar? Turn the funnels down until they are out of the red and giv'r.

Yes presieve might be part of the problem. Usually we just close it completely

Thanks for advice, preserve rod came off on one, still struggling with second. Will try new settings.

The presieve rods have to be changed every 4 or 5 years as they wear out
