Here in my part of the world I know of 6 806's bought new.
Ours and 2 neighbors had no fenders from the factory. They were in the way for the mounted corn pickers.
Two had round top fenders and one had flat top.
The one that had flat top also had a 706 for the picker with no fenders from the factory.
Only one of those 7 tractors came with a wide front.
