I'll take liberty to tell a parable:
14 years ago I bought a truck with a 454 Chevy V8. I drove 3 states away to pick it up. It didn't exactly say 454, so I bought it. Next day I discovered my truck could not have been equipped with a 454, wasn't available. I had a 366. I learned the 366 & 427 were the same except block & pistons were different.
The engine builder I had known many years described it this way: "If you can get them running just right, they have just enough power to drag a sick whore off a **** pot."
Something similar can be said for the Ford 9N & 2N. The 8N was a little more power, 4 speed transmission, and a few more features.
I love/loved my Cub! I have a rebuilt engine waiting to be bolted in. It'll come to life if this virus doesn't yield. Even more, from a practical point of view, I love my M. The M is a big tractor able to work.
In the day, (1938- 1945) tractors were being introduced to feed the world. Most were designed to literally replace horses. The Farmall A, and the Ford 9N are actually intended to tow the mower, plow, harrows your horses did before. Historically they are giants of change. Ford secured his place in history for the cost of his offering. Millions were able to buy Ford tractors!
The IH offering I will believe were better in quality, and dependability. They cost a lot more.
If I ran a museum, the centerpiece would be the Ford 9N, or 2N. Based on sentiment, I was closely connected with the IH dealer 1/2 mile away. My mother was the bookkeeper, my father was once an employee, My grandfather had dealings. I believe the IH lineup was exponentially more costly, but in function, eclipsed the Fords.
The Cub was an afterthought. Here, retiring farmers bought them for their garden. A dozen or more retired dairy farmers in my memory bought new Cubs most with lots of implements day after their auction.
