Hunter I-20 Ultra Rotor

Hunter I-20 Rotor

A High Performance Rotor with the Diversity and Efficiency for Any Site

With 22 nozzle choices, a 5.2mts to 14.3mts (17ft-47ft) radius, and 6 body choices, the I-20 is an indispensable rotor. Whether you’ve got a small area, sandy soil, or a mix of shrubs and grass, the I-20 is ready to water with efficiency and reliability. Recent improvements include automatic arc return; non-reversing 360, from 50 to 360 degrees; and a non-strippable, vandal-proof drive mechanism that prevents gear stripping and saves repair costs. Adding FloStop® control, easy through-the-top arc adjustment, and a standard drain-check valve all equate to a rotor that stands second-to-none in its class.
