I recently bought a Deere 6620 with very few problems. But, one thing I notice is that it has a shake. Where you notice it is in the steering column and the three levers (header raise/lower, hydrostatic, and reel height). Also the safety rail on the steps/platform. Everything sort of gets into a rhythm and is shaking back and forth. I have checked all of the bearings, straw walkers and belts. I am running a Deere 216 flex head on it. I do notice that when the head is running that the sickle bar moves back and forth ever so slightly in relationship to the stainless steel flex sheets on the head (less than a 1/8 to 1/4 of an inch). The head drive shafts are running at maximum. I believe the book says no more than 470 rpm and the digital readout in the cab can say 490 at times. Wonder if the stablizer under the the head is getting loose allowing extra movement??? Any ideas are appreciated. I don't know if this is really a problem and certainly is easily tolerated, just don't want to cause any damage. Thank you.
