The Toro 640 Series pop-up rotor (model 641-02-43) delivers commercial-grade durability and precision for athletic fields, parks, and large turf installations. Built with stainless-steel-encased components, brass fittings and engineering-grade plastics, it is engineered for long service life, reduced maintenance, and reliable irrigation performance in demanding environments.

  • Commercial-grade construction: Stainless steel-encased gear drive, brass components and a rubber cover provide impact resistance and long-term reliability.
  • Versatile coverage: Choose from five interchangeable nozzles and 12 fixed arcs — including the 90° sector — for precise sector control and overlap.
  • Performance specs: Radius 47–67 ft (14.3–20.4 m); flow range 6.0–25.0 GPM (23–95 LPM); recommended pressure 40–90 psi; maximum 100 psi.
  • Compact installation: 1" female inlet, 2 3/8" pop-up-to-nozzle height, 2 1/2" body diameter and 3 1/4" cap diameter for minimal exposed surface when buried.
  • Check-O-Matic advantage: Built-in check valve prevents low-head drainage and keeps laterals charged, maintaining up to 15 ft (4.6 m) of elevation change.
  • Low maintenance: Gear-drive design, stainless steel retraction spring and basket filter screen reduce wear and clogging; Toro backs the design with a five-year warranty.

Model 641-02-43 ships with the #43 nozzle installed and is specified for heavy-use turf and commercial projects where dependable coverage and low maintenance are required. Consult the included performance chart and installation/service instructions for nozzle selection, pressure guidance and recommended spacing. Replacement nozzles and service parts are widely available to configure the rotor for site-specific requirements.
