Features & Benefits

With 34 nozzle choices, a 17’ to 46’ 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.

• Patented automatic arc return feature returns the turret back to the original arc pattern if vandalized; adjustable arc from 50° to 360°
• Non-strippable drive mechanism is protected from damage if turned in the opposite direction of travel
• Part- and full-circle in one model for flexibility across landscapes and reduced inventory
• Headed and slotted setscrew allows radius adjustment with a Hunter wrench or flat-blade screwdriver
• FloStop closes the flow of water from individual sprinklers to change the nozzle or perform repairs
• Flat-top nozzles allow fast, easy insertion
• QuickCheck arc mechanism for fast arc adjustment
• Available stainless steel riser for extra durability
• Drain check valve prevents low-head drainage (up to 10' of elevation)
