Aren't there large commercial (tractor mounted) line trimmers?

Hi All,

What about using a "Knock Sensor" from a car and adapting it to
the application?   Not sure if this idea is worth anything, but
thought I'd throw it in as a suggestion.

You mean flail mowers, that flail chains around instead of line trimmer
nylon cord?

Actually, I did mean large commercial multi-head nylon cord line
trimmers.  Pretty sure I've seen such a thing.  I know they make large
single head models.  The flail mower sounds like a better alternative
however, especially in light of the rough terrain.
