Hunter 44001840 4 Inch Pop-up Adjustable Rotor

Product Description

The HUNTER 44001840 is a 4-inch pop-up adjustable rotor sprinkler head designed to bring the efficiency of rotary irrigation to zones that traditionally rely on spray heads. Built from ABS plastic with a rubber cover for durability and operator safety, this rotor delivers even water distribution across adjustable arc patterns. The design supports easy arc adjustment in the field, reducing setup time during installation and simplifying future service calls. Licensed irrigation contractors and landscape professionals install this head in residential and light commercial turf and planting bed zones where water-efficient coverage is the priority.

The 44001840 is suited for applications where a mix of coverage sizes is needed within a single irrigation zone. It can operate in tandem with larger rotors, allowing a single zone to serve both large and small areas without splitting into separate zones. This flexibility reduces the total number of heads required per zone and simplifies zone design. The head ships with a rack of interchangeable nozzles that are straightforward to install and swap in the field, supporting fine-tuned precipitation rate matching across the zone.

Key Features

• 4-inch pop-up height provides clearance over turf without excessive elevation
• Adjustable arc allows on-site customization of spray pattern without special tools
• Interchangeable nozzle rack included for easy nozzle selection and replacement
• Rubber cover protects the riser and reduces mower and foot-traffic damage
• ABS construction resists corrosion and handles typical soil and irrigation water conditions
• Compatible with mixed-rotor zones, reducing total head count and zone complexity

Compatibility

Designed as an OEM-style replacement or new-installation rotor head for residential and light commercial irrigation systems requiring a 4-inch pop-up adjustable rotor in spray-head applications.

Installation Notes

Installation should be performed by a licensed irrigation technician or qualified landscape professional. Shut off the irrigation system water supply and depressurize the line before removing or installing any head. The head threads into a standard swing-joint or lateral fitting and should be set flush with or just below finish grade to minimize mow-over damage. Verify arc and nozzle selection before backfilling to avoid reopening the trench for adjustments.
