Rain Bird 551 Series provides the right coverage for tee boxes, greens and other small areas with short and medium throw range. With Rapid-Adjust Technology your staff can make easy arc adjustments with the turn of a screw. Patented MemoryArc® retains two part-circle arc settings, so you can shift between full and part-circle operation in seconds. Nozzles for the 551 series offer higher flow rates and large droplets that cut through wind allowing you to apply water precisely where needed and in a shorter amount of time. 

  • Radius of 32' to 55' (9.8 to 16.8 m).
  • Can handle pressures from 60 to 100 psi (4.1 to 6.9 bars).
  • Holdback up to 10' (3.1 m) of elevation.
  • Nozzle design provides superior water distribution with less sensitivity to spacing difference.
  • Solid design and construction provide a higher degree of reliability and longer life than commercial-grade products.

Rain Bird® golf rotors are engineered for precise application and distribution uniformity, helping you get the most from your water source. With intelligent, easy-to-use features like a top‑serviceable design and quick full-circle/part-circle adjustments, Rain Bird golf rotors help you and your crew save time every week.
