I just traded my '79 6620 for a '94 9500 (I'll have to change my "handle"). I had the 6620 for 9 years and it did a good job, but I think that as the corn yields have inched slowly up, my speed was inching slowly down (6 row head). Like the others said, get a 7720 for 6 rows.
The 6620 served me very well, but I'm really loving the 9500...
