What crop are you switching from? I'm assuming wheat. For corn the rotor needs to be slowed down a bunch (shift the rotor gearcase to Lo, 350-400rpm) and open the concaves to something like 4 (somewhere around the corn icon on the indicator gauge). Beans are similar, but since this is only my second year with beans I don't remember exactly what the specs are off the top of my head.
Our old 1460 use to run 400 to 500rpm in corn with concave between 4 and 5.
In beans the concave would be 3 and rotor at 700 to 800 rpm.
If the beans are tough you may have to go over 1000 rpm.
If you hear rotor rumble ,,noise... speed up the rotor or you will plug the feeder or the rotor. The 1460 engine does not have enough power to pull the rotor out of a slugging condition.
I never have that problem with the 2388. I think the afx rotor and extra HP makes it hard to slug where with the 1460 we got out the rotor wrench many times.
The 1460 is a good machine just don't overload the rotor. Unplugging the rotor is a dirty job. also make sure you have the weed knives on back end of rotor. This makes a big difference in beans. They help empty out the rotor.
Sorry i should explained better. I know what the rotor rpm's and concave setting was when all the wires were in. I would like to know does the rotor rpm's need to increase or decrease and does the concave setting change with every other wire out of the 2nd and 3rd concaves?
The settings I described was for every other wire out in second and third concave. Since most of the thrashing is done over the first concave, the concave clearance and rotor speed will not really change very much. The big change with wires out is less rotor loss in beans and corn.
