Does anyone have a good logical explanation for the brown stripes the tires leave in the lawn? I have a bunch of condos that I mow. Mowed them last week. It had been about a week with no rain and temps in the 80's. Of the 42 lawns I mowed, two had the stripes in the lawn where the tires were. The guys are pretty upset about the stripes. I know it happens occasionally but I can't figure out what causes it. Must have to have just the right conditions or something. I bet Eric can't get my kind of stripes on a consistent basis.
