Multi-speed PTO coupler for RollMax 4-roller and 6-roller pumps. 5/8" shaft, 540/1000 RPM compatible, cast aluminum/zinc construction with set screws.
The Remco RMC585410 is the multi-speed PTO coupler for RollMax 4-roller and 6-roller pumps, designed to connect the R440, R441, R660, or R660SS directly to a tractor or equipment PTO shaft. Its multi-speed design supports both 540 RPM and 1000 RPM PTO outputs, giving operators the flexibility to run their pump on a wide range of tractors and equipment without needing separate couplers for different speeds.
Built from cast aluminum/zinc with set screw fastening, the RMC585410 provides a secure, reliable connection sized specifically for the 5/8" shaft shared across the R440 and R660 series pumps. It is also included as standard equipment in the R660C-TAK complete pump kit, making it the ideal standalone replacement or upgrade coupler for existing R440 and R660 installations.
