PTO pump couplings connect a hydraulic pump or auxiliary drive directly to the tractor PTO shaft. The quick-release spline coupling slides onto the PTO shaft and locks in place, while the bore end connects to the pump input shaft. Select the correct coupling by matching the PTO spline count and the pump input shaft bore diameter.

Available couplings

• B6691 - 1 3/8" x 6 spline, 5/8" bore, 95mm length
• B2711 - 1 3/8" x 6 spline, 3/4" bore, 95mm length
• B2712 - 1 3/8" x 6 spline, 7/8" bore, 95mm length
• B2713 - 1 3/8" x 6 spline, 1" bore, 95mm length
• B2902 - 1 3/8" x 21 spline, 3/4" bore, 95mm length
• B2903 - 1 3/8" x 21 spline, 7/8" bore, 95mm length

All couplings are 95mm in length. The 6-spline versions suit standard tractor PTOs; the 21-spline versions suit tractors with a 21-spline output. Confirm your pump input shaft diameter and your tractor PTO spline count before ordering.
