alt Hacker NewsA tractor does actual work like pulling an implement like a plow or spinning the PTO to power a machine like a wood splitter or well drill.
Airplane engines are rebuilt every 5,000ish miles because they’re constantly running at like 50% load, it’s much harder on the engine than moving a car, a tractor is very similar.
Car engines do very little work once you’re up to speed, it only takes a fraction of the max power available to keep the car moving. This is why EVs are possible.
Running a tractor engine under load requires a lot of energy, battery density isn’t quite there yet, diesel has around 50x more energy by weight than a battery.
Off by an order of magnitude. Average TBO (which airplane engines routinely exceed if they don’t rust out) is 2,000 hours assuming piston, or about 300,000 miles for a Piper Arrow at cruise speed.
