5 ft blades are near universal because that's the size for the old Ford tractors 1939~'50's and everybody had one. But an 8N has a half ton more weight and 27 hp.
Our Yanmars are like a 3/4 scale version of the Fords. So ground-engaging implements need to be scaled down proportionally.
Gotcha. I will keep an eye out for a 4' blade.
