It’s still possible to rototill in raised beds if you use an electric tiller like the Mantis. Rototillers are major labor savers. I have one that I’ve used in beds for some years. Incredible torque. Good depth: up to 10″, though with a limiter I usually use it at
just a few inches depth for prepping beds for replanting. A set of simple L-shaped brackets bolted to the tiller tine shield front, back and sides can help prevent the tiller tines from gouging the raised bed frame sides or ends. The tiller is light too: I carry it one-handed over my shoulder.
