Combines deflector in corn and soybeans

Hard to give a completely accurate answer to that question do to the varying conditions around the country.If you are running to the capacity of you return elevator then you will see an increase.If some other variable is the capacity factor then probably not.Ran a deflector last fall and was happy with the results because you can controll your air better and get much less MOG in the bin, less grain out the back and the return is no longer the limuiting factor.If you are running green, damp heavy beans the effect is less because no amount of air will blow some of that junk out.I would say ,if you harvest corn at 25% and below and wait until most of the leaves are dry or gone on beans the deflector will add good benefits.Glad I put one in mine..Wheat probably has the most dramatic results but corn and beans will benefit including easier storage due to less fine material in the bin..

I agree with your assessment. Any conditions that generate a lot of dry, fluffy material that can be floated out the back of the machine will benefit the most. One more way that the deflector helps is allowing the whole seive to be used. Without the deflector the heavy air blast in the front allows nearly no grain to drop through the first foot of the seive. By slowing that air down and using that area, the seive capacity is effectively increased, allowing slightly more capacity in conditions that are limited by seive loss.
