How to Identify and Adjust Your Toro Sprinkler Head

If you've recently moved into a home with an existing Toro sprinkler system, you might be wondering how to identify the model and adjust the heads for optimal coverage. This guide walks you through the basics using a typical Toro spray head.

Tools You'll Need

• Allen wrench (for spray distance adjustment)
• Flathead screwdriver (for arc adjustment)

Adjusting Spray Distance

Locate the small screw directly above the nozzle where the water stream exits. Using an Allen wrench, turn the screw clockwise to reduce the throw distance or counterclockwise to increase it. Make small adjustments and test the spray pattern until you achieve the desired coverage.

Adjusting the Arc (Rotation Angle)

On the back of the sprinkler head, you'll find a slotted screw with a plus (+) and minus (-) indicator on either side. Insert a flathead screwdriver and turn toward the plus sign to increase the arc (wider rotation) or toward the minus sign to decrease it (narrower rotation). This allows you to customize the watering pattern to match your landscape layout.

Pro Tips

Always adjust heads while the system is running so you can see immediate results. If you're unsure of the model number, check the base of the head for a stamped part number or consult Toro's online identification guide. Regular seasonal adjustments ensure efficient water use and healthy turf.
