Long-radius full-circle rotor built for single-row fairway systems. G-900 Series golf rotors combine durability, efficiency, and user flexibility for long-range on-course watering. Innovative TTS technology means every serviceable element of the rotor is reachable from the playing surface.
This Configuration – Electric Valve-in-Head
Electric valve-in-head with adjustable pressure regulation, on-off-auto selector, and a 190 mA (350 mA inrush) solenoid with captive plunger and internal downstream bleed.
Ships with the #53 nozzle installed. Nozzles are field-swappable with Hunter’s QuickChange™ system, so you can retune radius and flow without pulling the rotor.
Factory pressure regulation is set to 80 PSI at the inlet.
