I had a long lawn and decided to cross-cut in a checkered patern as it needed a double cut. On the 2nd pass, the original stripes were for the most part erased. How do you go about cross cutting? Do you switch directions every other week or do you double-cut each week? I know some grasses stripe better than others, but does it make a huge difference when cross cutting? I don't use stripe kits. Are they necessary to make the checkered pattern show up? How do you get a best result?
