I was mowing a lawn this past fall and my mower shot a piece of metal through the window of the house across the street. I have no doubt that this was from my equipment. The glass was still falling out as I walked over to look. The problem I have the metal was not put in the lawn by me. So is this my fault. Some years ago I shot a hockey puck at a customers door and put a small dent in it. In this case the home owner took all the blame for the hockey puck which was left in the lawn by a child of hers. Is the window any different? I have insurance to cover these freak things. The bill only came to $345. I plan on paying this unless anyone can offer good advice. Sometimes I think the "lawn guys" are easy targets to blame for these accidents..
