This 52SA Series rotor is designed for long-life, quiet operation, and maximum flexibility. Its protected, closed-case styling makes it ideal for use with "creeping" grasses, sandy soil, or other harsh surroundings. Its water lubricated, gear-driven technology allows for an almost silent operation, and maintenance free performance. It features a 3/4" inlet, a 4" pop-up, and a spray distance of 25 to 50 feet.
