To do those cool patterns in the lawn you need a piece of equipment that is called a striper (it's really just a roller that you put on the back of your mower.) It attaches to the back of your lawn mower (though it maybe tough to find one for the usual mower that you can go buy at Sears or Home Depot, etc.) and what it does is makes the grass lie down as you mow it. When the grass lies down facing you, it appears lighter because it is reflecting the light toward you; grass lying down away is darker because the light is reflected away from you.

It's actually pretty simple and you could get a lawn roller to have the same effect. Of course, by simple, I mean making the lawn look like it has light and dark stripes; checkerboard is more time consuming than difficult, but logos like the big leagues have are tough, especially for a guy like me with no artistic talent.

Sorry about the long answer.
