3-Row Spray Head System versus PGJ Rotor 2-Row System
Typically, in long and narrow landscapes, three rows of spray heads have been installed to
irrigate the areas. Now, with the PGJ, two rows can irrigate the same area, more efciently,
while saving dollars on piping, valves, stations on the controller, trenching, labor and most
importantly, water use!
