Ace BAC-10-RP8-QC Multi-Speed PTO Quick Coupler – 8-Roller Pumps

The Ace BAC-10-RP8-QC Multi-Speed PTO Quick Coupler provides a convenient connection between compatible Ace 8-roller pumps and a tractor's power take-off (PTO) shaft. Designed for pumps with a 15/16" keyed shaft, this coupler allows operators to connect and disconnect their roller pump without complicated installation procedures.

Its multi-speed design accommodates both standard 1-3/8" 6-spline (540 RPM) and 1-3/8" 21-spline (1,000 RPM) tractor PTO shafts, providing flexibility across different tractors and operating applications.

The die-cast coupler features a spring-loaded locking collar that allows for quick attachment and removal while securing the pump to the tractor's PTO shaft. This makes it a practical solution for agricultural spraying operations where pumps may need to be installed, removed, or transferred between compatible tractors.

Whether replacing a worn PTO coupler or setting up a new Ace roller pump, the BAC-10-RP8-QC provides a reliable OEM connection designed specifically for Ace 8-roller pump applications.
