Rotors

Rotors

Rotors and spray heads solve the same basic problem — getting water from a pipe onto your lawn — but they do it very differently. A rotor uses an internal gear mechanism to throw one or more streams that sweep back and forth (or fully rotate) across the zone, which means water lands more slowly and evenly than a spray head applying its whole pattern at once.

That slower application rate is exactly why rotors work best on larger turf areas. Spread a full-coverage spray pattern over a wide-open lawn and you'll get runoff on slopes and puddling near the head before the far edge of the zone gets enough water. A rotor's sweeping stream reaches farther and gives the soil time to absorb water as it goes, which is especially useful on sloped yards or heavier soil that doesn't drain quickly.

Most rotors are adjustable on-site — arc, radius, and in some cases flow rate can be set or fine-tuned after installation, which matters because a zone's real-world coverage rarely matches its spec sheet exactly. Gear-driven models keep that adjustment mechanism sealed away from dirt, grass clippings, and hard water deposits, which is the main reason rotors tend to hold their calibration longer than lower-cost alternatives.

Rotors are typically spaced farther apart than spray heads since each one covers more ground, so a rotor zone often uses fewer heads than a spray zone of the same size — worth factoring into a materials list before pricing out a new zone or an upgrade from an older system.
