I cannot speak to whether this is still true for modern farm equipment for two reasons. First, my family ran a small livestock operation and older machinery was more affordable to buy/run/repair and fulfilled our needs. Second, the farm has since been sold and now I'm a mere city boy.

Does IC mean integrated chips? I have certainly read that modern farm equipment is less repairable, and I would not be surprised if they played a role. But I don't claim any knowledge about that. I may also have the time scales wrong.

But damn, those machines were a marvel sometimes. Here is a particularly fun one, the square bale picker/stacker. https://www.youtube.com/watch?v=TUWrNZaLttQ&ab_channel=Thoma...
