Except that tractors are more dangerous than your car/appliance/whatever.
You'd be amazed the amount of carnage running a brushhog at 1000rpm will do when it was designed at 540rpm. They will happily throw the 3-4 foot blade right though 1/2in steel up to 300-400ft in whatever direction the wind takes them.
When that process is controlled by software all it takes is flipping the wrong high order bit in the PTO controller. On a manual tractor it's very clear when the PTO lever is in 1000rpm vs 540rpm(and usually on a separate lever from engagement) vs an opaque software stack.
