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.... It was towards the end of corn so we rented a 9500 to finish up. Next year we parked the 6620, sold the engine to a guy to put in his tractor, sold the chopper and some other parts, still have some good parts there. Still using the same corn head, 643, only have had to replace chains and lower sproket/bearings.
