Built for durability, precision, and long-term performance, the I-40 is engineered to handle the toughest jobs with ease. Featuring a fully adjustable arc from 50 to 360 degrees and a powerful spray distance from 44 to 76 feet, this rotor covers large zones efficiently with even water distribution and minimal dry spots. Whether you're working on municipal parks, stadium turf, or large residential lawns, the I-40 delivers high-performance results where consistency matters most.

Its 1-inch NPT inlet fits standard commercial systems with ease. The built-in check valve holds water up to 15 feet of elevation, reducing runoff, erosion, and system wear on sloped terrain. Six color-coded nozzles allow for tailored water delivery, while a factory-installed rubber top adds protection in high-traffic areas. Designed for speed, durability, and efficiency, the I-40 is the go-to rotor for contractors who demand real-world reliability.
