Toro 640 Pop-up Rotor, 360° Arc, #44 Nozzle, Check-O-Matic

The Toro 640 Pop-up Rotor with #44 nozzle and Check-O-Matic is a heavy-duty commercial rotor engineered for athletic fields and large turf areas. Its gear-drive design, stainless-steel retraction spring and durable construction deliver reliable, long-life performance under demanding use.

• Wide coverage: full 360° arc with nozzle #44 producing approximately 47–67 ft (14.3–20.2 m) radius; flow varies by pressure (about 6.0–25.0 GPM).
• Pressure and performance: recommended operating pressure 40–90 psi (2.8–6.2 bar); maximum 100 psi (7 bar); trajectory approximately 27° for consistent distribution.
• Durable construction: stainless-steel encased nozzle and drive assembly, brass components, engineering-grade plastics, and a standard rubber cover to minimize impact damage.
• Check-O-Matic: integrated check valve prevents low-head drainage and keeps laterals charged, reducing water waste and maintaining system pressure.
• Dimensions & connections: pop-up to nozzle height 2 3/8 in (60 mm); 1" female-thread inlet; compact exposed surface for near-flush installations.
• Serviceability & warranty: replaceable nozzle and stator assemblies simplify maintenance; 5-year warranty on select models—refer to Toro documentation for specifics.
