Orbit Irrigation 55661 Gear Drive Sprinkler Head

Product Description

The Orbit Irrigation 55661 is a professional-grade gear drive pop-up sprinkler head designed for residential and commercial irrigation installations. The head delivers coverage from 35 to 45 feet in radius and features a top-mounted adjustment mechanism that allows the technician to dial in full-circle or part-circle watering patterns. The arc is field-adjustable from 40 to 360 degrees without tools, and the head extends 4 inches above grade when pressurized. A built-in removable filter helps prevent clogging from debris in the supply line. This unit is suited for licensed irrigation contractors and experienced landscape maintenance professionals.

The 55661 is intended for use in professionally designed turf and groundcover irrigation systems where consistent, adjustable coverage is required. The gear-drive mechanism provides smooth, quiet rotation and is appropriate for medium to large turf zones in both residential and light commercial landscapes. It installs on standard threaded risers or swing pipe assemblies and operates within typical residential system pressure ranges. The top-adjust design reduces service time during seasonal arc changes or system modifications.

Key Features

• Coverage radius of 35 to 45 feet, suitable for medium and large turf zones
• Arc adjustable from 40 to 360 degrees directly from the top of the head
• 4-inch pop-up height keeps nozzle above turf during operation and retracts flush when off
• Gear-drive mechanism delivers consistent rotation with reduced wear
• Removable inline filter protects nozzle from debris clogging
• Full-circle or part-circle watering modes without removing the head from the ground

Compatibility

Designed as an OEM-style replacement or new-installation gear drive sprinkler head for standard threaded riser and swing-pipe irrigation systems commonly used in residential and light commercial turf applications.

Installation Notes

Installation should be performed by a licensed irrigation contractor in accordance with local plumbing and landscape irrigation codes. Shut off the irrigation zone valve and relieve system pressure before removing or installing any sprinkler head. Use PTFE thread tape on all threaded connections and verify proper burial depth so the top of the head sits flush with finished grade when retracted. Flush the supply line before final installation to prevent debris from reaching the internal filter.
