- Lawn coverage
- Rectangular lawns
- New grass
The default pick for square and rectangular lawns. The adjustable width/range and flow controls let you match the spray to a strip of new seed or a whole back yard, and the metal sled stays put. Its weakness is wind and water efficiency — that's where an impact or soaker wins.
Pros
- Covers up to 4,500 sq ft with an even, gentle rectangular rain that's kind to new grass
- TwinTouch width and range sliders plus a flow dial tailor the pattern to fit the yard exactly
- Weighted metal sled resists tipping and the 20 rubber nozzles wipe clean to clear grit
Cons
- The tall fan spray drifts and loses ground on windy days
- Uses more water and loses more to evaporation than a targeted impact or drip line
- Plastic gears and the nozzle tube can wear or clog with well-water sediment over time

Frequently Asked Questions
- How do you shape the watering pattern?
- TwinTouch sliders set width and range independently, plus a flow dial for volume. That lets you fit the rectangle to the actual lawn instead of watering the driveway.
- Why is an oscillating sprinkler good for new grass?
- It lays down an even, gentle rectangular rain rather than a heavy pulsing jet, so it does not wash out seed. Coverage runs up to 4,500 sq ft.
- What maintenance do oscillating sprinklers need?
- Keeping the nozzles clear. The 20 rubber nozzles wipe clean to clear grit, but plastic gears and the nozzle tube can wear or clog over time on well water with sediment.
