Why is it that I stripe new lawns or lawns that were previously stressed with my Permagreen? I can run a full route all day but the one lawn that was just recently installed (3-4 weeks old) or I have one lawn that stripes every time. I dont do anything different on these lawns. The one lawn I went back and criss crossed it and it striped again. Tire mark to tire mark is 6 to 7 feet.
