Need some help
 

I've got my grandfather's 70 model cub. I am trying to locate the serial number on it, or find out exact year it was made. I can't find the stamped serial number anywhere on the tractor, behind the rear tire I found a number stamped upside down into the actual frame. But there's no U in the middle for me to determine anything. I'm curious as to what year it was made. Any help to determine this would be appreciated. Thanks!

This is the 70 model I'm trying to find a serial number on. Can't find it anywhere.

The Serial Number for the 70/100 series are located here. There was NO serial number format the utilized the "U" back then. The serial number range was 65459 to 127160.

Ok thank u. I took pics of the number I found, so with that, how would I determine the year it was made?

This is the number I found.

So it's not the big number it's the small number on that plate?

the small number stamped into the square block is what your looking for.
the number you show in pix is a casting number:beerchug:

So this would be the serial number?

Thank you all for your help. I truly appreciate it

Now would this work also on the 122 model? Because I don't have a stamped plate and the spot where I found the s/n for the 70, the 122 doesn't have any numbers there.
