Combines rotor gear High or low for soybeansIJ

[Deadduck]

Don't know which combine you're running, but when I ran a 1680 I liked to run in high gear. That way if I choked the rotor up, all I had to do was switch to low gear and open up the concaves. The variable pulleys were already in slow speed, so switching to low gear made it a lot easier on the machine to unchoke the rotor. Now that I run a 2388, I use middle gear for soybeans.

I was always told that it is best to run on the high side in beans so that the driven sheave on the rotor belt is more closed at 'bean' speed,therefore,it can spread and 'give' more easily when a slug goes through.Hope I explained it right.

On the old 1400s and 1600s i tried to run in low but could not get enough rpms it worked ok but could not feed them in near as fast i thought

Would recomend running in high gear if you want to run 600-700 rpm on rotor. low side won't go that high, plus, the faster you run the rotor, wether in high or low gear, the further the belt goes into the torque sensing pulley on the rotor gear box. Running the belt that far in on the pulley can lead to pemature failure. In my experince, 700-800 rpm works best, but have gone higher if beans were extra tough.

I don't know why this question was posted twice on here I only did it once.

run it in high gear. that way if it chokes up you can put it in low gear to get more torque to run it through
