Today I worked on a 9860 premium that had the high capacity feed package, which includes the rice feed accelerator. I believe this accelerator is run around 1000 rpm in hi speed vs. the 800 rpm of a standard one. This combine had a moderate vibration that I quickly isolated to the feed accelerator by dropping the tensioner lever and running it again. These accelerators are full of holes and allow a lot of dust in, but not out. When the dust sits to one side, you get a vibration. He will probably buy a PF accelerator from me to fix this. My question is, how many machines out there are having dust vibe issues in the accelerator? Particularly units with high-cap feed package.
