The Remco RMC585410 RollMax Multi-Speed PTO Coupler is a professional-grade PTO drive coupler designed for compatible RollMax 4-roller and 6-roller pump systems. Engineered for agricultural spraying and PTO-driven pumping applications, this coupler provides a secure connection between compatible RollMax pumps and tractor PTO shafts while supporting both 540 RPM and 1000 RPM PTO operation.
Designed for use with RollMax R440 and R660 series pumps utilizing a 5/8" shaft configuration, the RMC585410 allows operators to run spray systems across multiple tractors and PTO configurations without requiring separate couplers for different PTO speeds.
Built from cast aluminum/zinc construction, the RMC585410 is engineered to withstand vibration and torque loads commonly encountered during agricultural spraying and liquid transfer applications. The set screw fastening system helps maintain a stable, vibration-resistant shaft connection during continuous field operation.
