Do the checker pattern but when you mow do a pattern of 2 cutting widths down and 1 back and keep doing this! Make sure your stripes are from corner to corner going diagnolly across the lawn. Then when you get the frist pattern in there you have to start the 2nd pattern so you will get the nice diamonds at the 90 degrees to each other. This puts some nice diamonds in the lawn. I found this information on the simplicity lawn mower site.
