Besides pre-marking and avoiding sprinkler heads:
- Can an aerator dig deep enough to strike the underground sprinkler lines?
- Can a sod cutter cut under grass deep enough to strike the underground sprinkler lines?
Any other concerns?

No. I've since discovered most sod cutters only dig 2-½" max deep and most aerators only punch 3" max deep. Sprinkler lines in northern states are usually 6" deep.
If someone has a better answer I'm willing to change my accepted answer to yours.
