Product Information


The Hunter I-20 Ultra is your one-stop-shop for sprinkler rotors. With the ability to cover a radius range from 17 to 46 feet, you now have the choice to use only one sprinkler compared to having a variety of rotors and sprays.

Let’s sum this up: 18 nozzles + 17 to 46 foot radius + 6 body choices = 1 indispensable rotor. That’s the difference of the I-20 Ultra, whether you’ve got a small area, sandy soil, or a mix of shrubs and grass. Now we’ve added 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 you repair costs. Adding FloStop® control, easy through-the-top arc adjustment, and a standard drain-check valve all equate to one prime product.
