I'm gonna fess up!!! LOL. I was doing a new account last week and didn't really walk the yard to check things out. As I was riding I saw some loose stones and hit the pto I thought in time. Out of the corner of my eye I saw glass shattering. Lucky for me (I guess) it was the back window of my Blazer. Made a quick phone call to the glass company and they wanted $450.00 to replace it. With pending rain I called a local salvage yard and lo and behold they had one already taken off and waiting for me. $75.00 and they helped me put it in! Lesson learned........walk a yard before cutting.
