As the kinda useless guy in the video noted "not financial advice".
Farm implements tend to be built to last, autos not so much. The pre-WWII tractor my dad bought (used) when I was a little kid did a lot of service (mostly as a mower), and at least 25 years ago he sold it to a broker, then 10 or more years ago it showed up for sale about 12 miles from here, in a large, large yard in a posh area, and since sold it is probably still in service somewhere.
The John Deeres also last a really long time. All such equipment has to be properly maintained of course, but it won't be surprising when the older ones around now enter their second century of service. :^)
Hard to sell new ones except in a growing (sorry) market -- such as China, which started mechanization of its agriculture at least 60 years after the US did.

The old ones last WAY longer than the new ones BECAUSE the new ones are loaded with electronics. The maintenance you refer to is vastly in addition to the maintenance needed before the electronics were added.
