I'm not very much into after 1964 Farmalls and newer.
A friend died leaving about a dozen tractors for his widow to sell. One is a small Farmall with a Cub decal on the hood. The sheet metal looks more similar to a 140. The serial number 223170 makes it a 1963. First, am I right on serial number because I got it from a cub list (Farmall, International) on this sight?? Second, what is the difference between a 140 and a Cub??
