Hey, What methods do they use to get those patterns in the pitch? - Thinking of doing the circles in my yard Cheers
Easy. Adjust the blade height on your lawn mower. It's a little trickier if you want to sell advertising space, but it shouldn't be too hard if you just cut out a template to cover the grass.
You may want to find this book: "Fenway Park's head groundskeeper, David R. Mellor, has written a book called Picture Perfect: Mowing Techniques for Lawns, Landscapes, and Sports. Mellor was one of the first groundskeepers to mow patterns into stadium turf, and his book shows the average homeowner how to reproduce these patterns in his or her lawn." http://gardennetwork.tripod.com/garden_store/lawn_and_garden/isbn_1575041510.htm
as someone that used to do "turf management" to put himself through college i can answer your question. first off all, it depends on what kind of grass you have, you can only do certain things with certain kinds. i was mainly taking care of an american football field and the main thing that we used to do was alternating 10 yard strips of dark and light. with the particular type of grass that was on the field (its name escapes me at present) had a "dark" and "light" side on the individual blades of grass. obviously, taking care of a quality sports field requires that you suck up or bag the grass just like on a conventional lawnmower, except these are infinitely bigger. one of the mowers we used had 100 inches across of blades (with this retractable, collapsable thing too...very cool.) the way we achieved the dark and light strips was to use a mower that had suction and we would only drive it north in the strip we wanted dark and we would only mow south for the alternating light strips. is it a royal pain in the butt to do? yes. does it look cool on TV or sitting way up in the stands? yes. the circle pattern is basically a variation on the strips, but much more difficult and would require fairly sophisticated equipment.
In my town they let the aliens do it. The spacecraft-travelling aliens, you clod - not the INS office-line-crowding ones.
