I went out to do my normal Monday yards today and noticed two yards that had terrible striping right underneath where my tire tracks were from last week. Let me preface by saying that I only to the mowing maintenance on these two properties, they are serviced weekly, grass is bagged, cut at an appropriate height (3.5-4"). I had sharp blades on that morning and the mowers were clean top to bottom and under the deck from washing them during the weekend. These first two pictures are of the worst occurrence of this on the customers front yard followed by two pictures of the back yard. The back yard had this damage as well, it wasn't as severe and is mowed with a different mower.
