What Makes PGP the World's #1 Gear Drive?

Hunter PGP - #1 Gear DriveThe Hunter PGP Rotary Sprinkler has been and continues to be the world's best-selling gear-driven rotary sprinkler. But being first is not simply limited to sales figures. The Hunter PGP also holds the distinction of being the first irrigation sprinkler to give the irrigation industry some of the "taken for granted" features that continue to set it apart from the competition. Some of the Hunter PGP "Firsts" include:

  • Through the top adjustment - wet or dry - no parts to remove, easy adjustment, precise
  • Full rack of nozzles included with every head - allows you to custom-tailor sprinkler performance to the site's needs
  • Rubber cover standard - keeps dirt out, improves safety

It's no coincidence...being first in developing technological advances has had more than a little to do with being first in product sales. No wonder products like the Hunter PGP have earned Hunter the reputation as "The Irrigation Innovators."
