Alright, while doing clean a clean-up on Friday, at appears some stones were in the lawn and the mower happened to catch one and throw it shattering the window of a truck driving by. Now, the mower had a recycler kit in it, which completely covers the discharge, so the fact that a stone escaped and flew about 50 feet is completely beyond me. Anyways, I was the one on the mower when it happened, and had no clue that a rock had escaped. At first I thought this guy was driving by with the window already broken by and saw a nice lettered truck and guys working and stopped looking for patsy to replace his window. However an employee was standing at the back of the truck fueling a blower and says he saw/heard it. Now originally I gave the guy a card and said get an estimate to fix it and get with me. Well, the estimate was laying on the fax machine today, and lets just say, it's not a nice number. Now that you know the story, my question is, am I really even responsible? I mean if you are happy homeowner, and you are mowing your lawn with your 21" on Saturday morning and throw a rock and break someones car window, do you have to pay, or is it the vehicle owners responsibility to just turn it in to their insurance? I know it's not good biz, but I'm half tempted tp just tell the guy, "Hey, I didn't see it happen, the guards were all in place on the mower, if you think you can prove I broke your window, sue me." I'll probably end up cutting the check for this, but just looking for some opinions.
