Knowing John Deere, no.
Maybe dad and an uncle’s collection of vintage tractors that someone can work on will be valuable someday.
I help a farmer part-time near Lawrenceburg, TN. He farms with late model Deere machinery, but has enough 20 series tractors (built from 1963 to 1972) to outfit a half dozen farmers. There are at least two others in that county that could do the same.
Another family near there specializes in rebuilding and selling Deere farm tractors built in the 1960s through the early 90s. They have an impressive collection.
The main worry is if rebuild and repair parts become unavailable.
