I ran a 6620 for 10 years. It is a decent machine but we had to repair alot. Finally gave up and bought a used 9500. Made that 6620 look like the threshing machine. We had many of the same problems mentioned here! What was the last straw was the counter shaft bearing behind the big pully. I collar came loose and the shaft turned inside the bearing. Of course you can't see any of this. Eventially the combine would shake at certain RPMs. And about the same time I left the fuel cap off....
