And it still works.
Things were made different back then.
I looked up the manual, you got everything you need to repair it. Maintenance is extremely easy. Even have electric schema.
Now my BMW, I looked into the manual how to change a light. It said to go to the dealer lol.
Fuck the modern car / tractor / tools. I blame the people for that, we went from customer that demanded to be able to repair their stuff to people who are now mechanically illiterate. I'm not sure they would even know how to replace a tire on their Tesla :)
That's why manufacturer have all the latitude to do what they do. And that's why it didn't go very far with farmers.
