How do you tell a Massey Ferguson 3 cylinder 35 to a Massey Ferguson 35x Vintage tractor

Focused squarely on identification: how to tell a standard Massey Ferguson 35 three-cylinder from the 35X using the build plate codes, dynamo bracket design, and RPM differences visible on the hour meter. The creator references an original factory brochure to settle the diff-lock debate and briefly fires the engine. Best for vintage MF35 owners or buyers trying to confirm which variant they actually have.

Posted by the Mr B channel, which appears to be a personal enthusiast channel with a family connection to this specific tractor, suggesting an owner/hobbyist perspective rather than a commercial one.
