Hunter I-25 Gear Drive Sprinkler

This patented feature returns the turret to the original arc regardless of where it is turned. This ensures vandal protection in any environment.

Patented non-reversing 360 for part- and full-circle in one model, from 50 to 360 degrees.

As air in the system piping can cause long-term damage to rotors and plumbing, the drain check valve keeps lines from draining when the system is shut off. This saves water, reduces liability, and increases system life.
