Rain Bird designed the Eagle-series rotors in response to golf course superintendents, designers, builders and owners who rank durability and efficiency as a rotor’s most important features. In prerelease performance testing in the field, Eagle rotors were said to be 23% more efficient in terms of distribution uniformity, using less water on the course and saving energy while still delivering noticeably more playable grounds. Design incorporates tough new materials, friction-minimizing design tolerances, new molding processes and new assembly techniques. Rain Bird Corp., Tucson, Ariz.
