The soil my yard sits on it extremely rocky. It's very nice soil, all
glacial till and stream bed composition, but more rocks than I care to
count. Digging a hole is an exercise in futility as I will encounter round
rocks about the size of a baseball or grapefruit more often than not.

I would like to take a rototiller to a patch of land but fear what will
happen with all those damn rocks. What kind of things should I look out for
when rototilling really rocky soil? Do I need a special tiller, should I
simply not do it, would renting one be a bad idea (I'm thinking of damage to
the unit), would a rototiller not do a good job? Are there other options
besides a tractor?
