Brand: Hunter Industries SKU: I20-6ADS
Product Overview
The Hunter I20-6ADS is a 6-inch pop-up I-20 gear-drive rotor with a stainless steel riser, adjustable arc, and factory-installed check valve. It is designed for demanding residential and commercial turf applications where a taller pop-up helps clear established grass and the stainless steel riser adds durability in high-use areas. The adjustable 50° to 360° arc allows the rotor to be matched to corners, edges, and irregular landscape boundaries, while the nozzle selection determines the final radius and flow for the zone.
The built-in drain check helps reduce low-head drainage on sloped sites by holding back water when the system shuts off. With the correct nozzle and operating pressure, the I-20 family can cover medium-to-large turf areas while providing the serviceability and adjustment expected from a professional gear-drive rotor.

Compatibility and Installation Notes
Select the nozzle and spacing from the irrigation design rather than choosing by radius alone. Available pressure, nozzle flow, precipitation rate, wind exposure, and head-to-head coverage all affect performance. Flush the lateral line before final nozzle installation, set the arc and radius after the rotor is operating, and keep the top of the sprinkler level with finished grade.
Frequently Asked Questions
Is the I20-6ADS a full-circle-only rotor?
No. This model has an adjustable arc from 50° through 360°, allowing both part-circle and full-circle coverage.
Why choose a 6-inch pop-up rotor?
The taller riser helps the water stream clear established turf or slightly taller groundcover that may obstruct a standard 4-inch rotor.
Why Buy the Hunter I20-6ADS from Big Frog Supply?
This model combines a 6-inch pop-up, stainless steel riser, adjustable arc, and check valve in one professional rotor. Big Frog Supply presents the operating range and application details needed to compare it with shorter, plastic-riser, or non-check-valve I-20 configurations before ordering.
