Engineered for performance and built to withstand the elements, this rotor delivers even coverage and flexible control across a wide range of lawn and landscape applications.

Nozzle trajectory options include a standard 25° angle and a low-angle 13° nozzle for wind resistance or slope applications. Whether you're replacing an old sprinkler head or building a new irrigation system, the PGP-ADJ delivers industry-leading reliability, smooth gear-driven rotation, and customizable watering with every use.
