Maybe blasting stumps at 6 AM when they’re trying to sleep it off might get their attention.
Well, I do have a very loud chipper shredder which a ran up just an hour ago to shred some brush. I think they just turned the music up louder.
You don’t have a noise curfew time in your city/county?
I always thought it was a great idea to mow the lawn at daybreak with the biggest loudest mower I could find. Be sure and take the muffler off of it first. Put as bad spark plug in it so it backfires often. I got a 20 HP riding mower that sounds like a shotgun going off. Move slow and take plenty of breaks with the engine still running wide open. Also, you wouldn’t believe how loud a big boat motor is while it’s running out of the water with just a water hose hooked to it to keep it cool. It will wake the dead. It will literally make the neighborhood dogs (including theirs) start howling.
I took the muffler off my tractor and ran it up and down the property line mowing.
At five AM one morning after the neighbors had a very loud party till three am.
About 50 feet from where they were all camping.
We came to a understanding :)
