Hunter releases new PGP-06 rotor The new product prevents nozzle stream blockage and wasted water. SAN MARCOS, Calif. — Tall grass can block or deflect a rotor’s nozzle stream, which leads to dry, underwatered patches and muddy, overwatered areas. The new PGP-06 solves this problem with a taller pop-up height. At 6-inches, it can clear tall turf and deliver water efficiently without interference. "When the nozzle stream is blocked by turf, it can’t work effectively. The new PGP-06 rotor pops up a full 6-inch, which positions the nozzle high above the turf. This allows it to deliver water unimpeded,” said Steve Hoveln, product manager.
