Personally, I have given up on rototilling.
It breaks my heart to see worm hamburger.

Very few worms are harmed during rototilling, the vast majority burrow
deeper then you can till as soon as they feel the vibrations of your
machine. Earthworms are both male and female, each produces both eggs and
sperm. Earthworms reproduces at a far greater rate than you can rototill
them, fortunately There is no shortage of earthworms, all the world's
earthworms weigh more than all other animal life combined. If not for the
preditors that live by feeding on earthworms the planet would be so over run
with earthworms so as to make the planet uninhabitable for any other animal
life. Don't argue with me, argue with Charles Darwin.
