The radius of a center pivot irrigation system is typically less than 500 meters (1,600 feet). However, the most common size has a radius of 400 meters (approximately 1/4 mile).
While the maximum length can approach 500 meters, variations exist depending on factors like field size, water source location, and specific crop requirements. The 400-meter radius machine is prevalent because it efficiently covers approximately 50 hectares (125 acres) of land in a circular pattern.
