Rain Bird R-50 Rotors: Chronic Retraction Failures

50+ R-50 rotors, 7 years old. Half replaced over years—most common failure: won't retract, hanging on wiper seal at arc adjustment ring. Owner feels it's a design flaw; Rain Bird charges for support. Toro rotors lasted 10+ years with fewer issues.

Known R-50 Weakness

The R-50 has a long-documented retraction problem. The expert recounts a 6-acre park with 250 R-50s requiring dozens of replacements after every mowing. They switched to Hunter I-20 rotors 20 years ago and resolved it.

Recommendation

• Yes, they should last longer than a few years.
• When replacing, choose a different model (Hunter I-20, Rain Bird 5000/5500, Toro T5).
• Rain Bird's warranty support is notoriously difficult.
