In Reply to: 9n serial numbers around 66645? posted by Shannon Henderson on November 14, 2017 at 19:37:09:
Your *9N-66645* tractor would be a 1941 9N. The grille would be what was known as "the 41 grille" since it was used only 1 year, and change made at s/n 45899. It was a steel vertical round bar style with a closed center. It replaced the fragile aluminum horizontal bar grille. The steering wheel would have still been the 4-spoke style as it wasn't changed until s/n 80770. You will have a very difficult time trying to locate originals of either of those items, but, Dennis Carpenter repops them new nowadays. Go to John Smiths' web site and learn more....see LINK below...
