Subject: setting a 7120 combine


I am having a lot of returns. I am running soybeans that have most of their leaves still on the plant. Beans are 2.5 to 3ft tall. I also have a few green waterhemp plants.
I hate to run the rotor under 650 but may be that is the answer.
So far speeding up the rotor and opening and closing the concave seems to have no effect.
If I run the fan over 1000 it starts showing beans going over the back. Not continuously but in a pulsing pattern.
For now I have the sieves set at 14 upper and 12 lower. Pre sieve is set in the middle.
About 2.7 mph with a 35 ft draper is max for my horsepower.
Any suggestions or is because of all the leaves going through.
