Hi, my name is Tobie from Oklahoma. I traded my 97 GMC Yukon for a what I believe is a 1946 or 47 9N with a brush hog. I think he got the better deal but I was in the need. I don't know much about tractors this old but I know it starts and runs, it has an oil leak (seems to be rear seal), the lug nuts are lose on front wheels and when you tighten them they snap off, one finder is lose, the tool box needs replaced, and it seems that the PTO overrun shaft is very lose.... but it dose run and it dose cut the brush....
 I m not sure it is a 9N cause everything I have read says that they stop making 9N's in 1941 and that they used 9N parts to make the 2N but I have a 9N serial number (9N221277)
I have plans to work the poor thing as hard as I can but I am also going to fix her up as best I can. Hope this Forum Can be of some help.
