The Zamboni Pattern is a field tending pattern, so named for it's resemblance to the pattern a zamboni takes when resurfacing an ice hockey rink. It is advantageous if time is a factor, as it cuts down on the time spent turning the equipment, usually a combine harvester thresher, by eliminating half of the three-point turns. It is especially useful in the early stages of a game as the turning radius of the starter combine, the Sampo Rosenlew Comia C6, is approximately 28 feet (8.6 meters), double the width of it's wheat header. The Zamboni Pattern becomes less useful at later stages of the game as combines with larger headers will not use the full length of the header after the first turn.
