Last week when i cut lawns during the day, my riders rear wide tires where they ran over the grass in multiple yards, left "burnt" marks in the grass. This was on several lawns in NJ. Its not where i turned or stopped and ONLY from the rear large drive tires path. Its back and forth pattens in the various yards when i cut them. Could this be because these lawns were too dry, too hot out? time of day? My mower is 1000lbs , a 61" deck ferris 1000z, has about 10" wide drive tires.
