PTO Over-Running Coupler Adapter - Female Spline 1 1/8'' - 6 Spline x Male spline 1 3/8'' - 6 Spline with Locking Pin - Rated up to max 75 HP
Ford, IH Farmall Tractor (with original 1 1/8" PTO Shaft) that has not been converted to 1 3/8" PTO Shaft
This does not fit Tractor models that have been converted from the 1 1/8" PTO Shaft to 1 3/8" PTO Shaft
Your model Tractor must have a hole in the PTO Shaft - if you do not have a hole, you will not be able to install this Coupler and may want to consider purchasing a 1 1/8" to 1 3/8" Conversion kit and the Quick Disconnect Coupler - SKU 51A100
Uninstalling and re-installing Coupler with locking pin will weaken the pin. We do offer replacement pins for this specific Coupler if needed.
