Hello; Those old classic tractors were built to last a couple of life times and beyond! This is what I love about diesel engines. They can sit forever, and when you finally go to start it back up, most of the time all you have to do is put a new battery and some ether, and she fire up and be a happy engine. As someone who has restored a couple of old pieces of equipment, I can tell you there is nothing like seeing the engine come back to life and run again. Banners aside it is definitely a great video with very interesting old-school machines that could and will run longer than anything built by today's standards guaranteed and no they might not have as much power but definitely less tear downs and rebuilds! Diesels are just one of those beasts that never really die they just slumber and like an old man they're groggy and cranky to get started again.
