ProTech Safety System Equals the Best Defense

The ProTech™ safety system makes the exposed portion of its heavy-duty rubber cover as small as possible to avoid players or children. The rubber boot around the cover ensures that no metal or hard plastic pieces cause added injury either. So the tops of our ergonomically-designed I-40 Ultra, I-35 Sierra and I-25 Ultra commercial rotors are flexible and made to minimize contact.

Stainless Steel Rises to the Top

Why stainless steel? Nothing is better. Whether you’re dealing with unpredictable soil conditions, unforgiving climates or heavy foot traffic, this solid riser takes it all in stride. Stainless steel risers come standard on I-60 and I-40 Ultra rotors, as an option on I-35 Sierra, I-25 Ultra and I-20 Ultra. Take a Hunter rotor, add a stainless steel riser, and you’ve got an equation for lasting muscle.

Opposing Design for All Sides

The I-40-ON gives you all the winning features of our other I-40 models and an opposing nozzle design for excellent water distribution. With primary and secondary nozzles on opposing sides of the turret, streams arc in opposite directions as the sprinkler rotates. You get outstanding midrange and close-in watering.
