I agree with the earlier posters below.
The 6** series tractors were an improvement over the NAA (Jubilee) tractors, which were a significant improvement over even a late model 8N.
The 8** series tractors were more powerful and heavier than the 6** series tractors but similar in other respects.
I've worked both good, late model 8Ns as well as a very good 860 and found that I could do almost twice as much work with the 860 as I could do with the 8N. The 860 used much more gasoline but was doing much more work.
