MF 40 Industrial Serial Number

[lacord03]

I recently purchased an MF 40 industrial tractor, and would like to find a source to confirm the age. I was told it was a 1974 or 1975 by the owner, but another source believes it is a 1976. While I have found the serial number, I haven't had any luck finding a source to tell me the age. Please let me know if you are able to provide a website or source. Thanks.
