I recently bought a 1970's John Deere 7520 at an auction. This tractor had both the serial tags removed from the rear axle and the engine. I would like to identify the year and some other information about this tractor. I talked with John Deere and they said I need one of those two numbers to find get the full serial number. When I shine a light where the engine serial number was I can faintly see some numbers/letters. Would these numbers have been stamped on the aluminum plate then installed on the tractor or would hey have been stamped after installed on the tractor? I can't imagine just the friction from vibration would have made part of a serial number visible. Has anyone else had luck finding a serial number this way. Does anyone have any tips for how to recover a serial number if I can't get the numbers to show this way.
Thanks
