And even if you are a farmer, an american pick-up seems to be a rare choice around here. If you see something pick-up-like, it's usually more a variant of UniMog https://en.wikipedia.org/wiki/Unimog .
And for the "small-time farmer without enough money to buy lots of equipment" (rare nowadays), tractors with tons of included functions were often more practical: https://de.wikipedia.org/wiki/Fendt_GT (no english version, sorry). Since Germany is more dense and distances are smaller, low speed is less of an issue I guess, compared to the US. And you can pull real farm equipment, which a pick-up car usually cannot.
