We had a 6 row head we used on a 9500 with single wheels, then two years ago, updated to a 97 9500 with duals and had to go to an 8 row. The tires stick outside the head and if the rows were not planted perfect, crop would get trampled. This fall we updated again to a 9650STS with duals and the wheel base was the same as the 9500. So I'd say you'll need atleast an 8 row.
