Check to make sure the bolts on the gearcase behind the cab are tight. Could possibly be a bent countershaft. Have you slugged the separator recently? Could also check the U-joints on the shaft that runs through grain tank.

I have the same problem, but it seems fairly random, it only happens every so often. I have found that if I ever shut the separator off for a min, then start it back, I feel the vibration, but only for a few min until it goes away. I think it has something to do with the way dust and dirt and trash may be settled around the cylinder, but once it runs, it evens out or something...Just my idea

If u clean out the cylinder completely and the vibration is gone put 1 golf ball between each spider. When you shut the separator down they will bounce around and help knock the dirt out or keep it from packin in there. I have been doing this for 12 years now.

Never thought of a golf ball! The vibrations happen to me occasionally. As soon as I notice it, I shut down the seperator to a full stop. The remaining dust falls through the bottom bars, start it up and it runss perfectly smooth. Never fails. Pretty sure I read that in the manaul somewhere.

if you clean the bars out and vibration continues take the beater belts off and see if it is the cylinder or the beater that is out of balance. could be that the beater is full of dirt and chaff causing the vibration
