You can get a trip plow which will tilt when you hit a rock, rather than snag on it.
I have a 101 Ford single bottom which will do that, otherwise I would have broken something major a long time ago.
For those unfamilar with the old drawbar plows - notice the rope used to lower and raise it.

These have spring loaded hooks and are used with a twisted clevis and plow separates from tractor when large rook or root is encountered. Many not so smart (noobie) farmers secured the rope to the seat suspension springs on early tractors ex. IH model M. Amazing how fast your butt drops, quickly learn that bailing wire can be your friend.
