My grandfather, rest his soul, was a 3rd generation rancher and farmer. He bought 2 John Deere tractors in the '80s and used them for 35 years. They are still being used to this day on the ranch. Growing up, I visited the ranch regularly. Farming and ranching is very hard on equipment so the tractors often needed repair. My father and grandfather could seemingly fix anything on the tractor without even needing to go…
Look at how popular 40-year old tractors are :)
It's never been a better time to create a good old repairable machine.
