Electric tractors. What could go wrong?
What’s the matter with you? Electric tractors will work. Just have a big windmill on top of them to generate the electricity and farmers can run around the fields totally free, anytime they want. Tractors need weight for traction, several lithium batteries will do the trick. If the farmer gets cold, no problem, sooner or later the batteries will start fire and the farmer can be real toasty.
So you see, there’s no problem.
