> The technology itself is not the issue... In a way, it is. There's no argument today's machines (including even consumer cars) are more technologically complicated than those of 40 years ago. There's more stuff (read features) that can break, and there's more microcontrollers and embedded computers that run software (read bugs) with sometimes intricate behavior. Those 40-year old tractors are easier to maintain because everything is mechanical, so it's easier to diagnose and easier to fix.
