The serial number should be on a small plate just forward of the steering wheel.


When the serial number plate is missing look just in front of the dip stick on the hydraulic/transmission housing. There you should find a vertical number something like ‘12-8-9’. This gives you the day/month/year of manufacture of that casting. You might find similar numbers just forward of the steering drop arm and above the dynamo.

If it is a 6 volt tractor there is a year date on dynamo / distributor / and starter motor if they are original.
A date code such as 12-8-9 would mean the casting was made on 12th August 1949


MF 35/65/135

The serial plate should be on the bottom of the dash board to the right on this range of tractors.

There is a date code in front of the transmission housing dip stick (response lever on 135) and again in front of the steering drop arm.

I should be able to date your tractor to the year it was built from these codes. I need to be told where they were found.

On a few early tractors there was a date on the front end of the engine sump.
