This listing is for one overrunning coupler / clutch with 1-1/8" X 6 spline male end with 1-3/8" X 6 Spline female end. This clutch is used to protect the operator and implement when used on tractors without "Live Power" to eliminate the implements ability to push or drive the tractor as it spins down to a stop. Includes quick mounting pin and roll pin for mounting In agricultural equipment an overrunning clutch is typically used on hay balers and other equipment with a high inertial load, particularly when used in conjunction with a tractor without a live power take-off (PTO). Without a live PTO, a high inertial load can cause the tractor to continue to move forward even when the foot clutch is depressed, creating an unsafe condition. By disconnecting the load from the PTO under these conditions, the overrunning clutch improves safety.
If you are not sure if your tractor has live power please contact the tractors manufacturer for more information!
