over running PTO

Does anyone have any information on a good source to purchase an overrunning clutch to slip onto my PTO for my Ford Heavy Duty Industrial tractor. I bought one from Tractor Supply and one year later it is broken. I don't mind spending some extra money for something with a better quality that will not have to be replaced so quickly. Thanks for any input.
 
Someone started making heavy duty ones lately. YT might sell them here. I saw some on fleabay, bushhog's probably do a number on them. A bushhog with a slip clutch is probably easier on everything turning it.

A slip clutch and an over running clutch are two different things that accomplish two different objectives. A slip clutch allows the drive train to slip if the load becomes too great, and is used instead of a shear pin. An ORC is a ratcheting mechanism that allows force to be transferred in one rotational direction but not the other so that a heavy implement does not cause the tractor to keep moving when the clutch and brakes are applied on a tractor with a transmission driven PTO. So having a slip clutch will not help keep an ORC from wearing out unless there is constantly to much load to where you would always be breaking shear pins if it had a shear pin instead of a slip clutch.

You need to size an ORC for the horsepower of the tractor and implement. And if the seller doesn't state the maximum hp it is designed for then you should buy from somewhere else. The term "heavy duty" means different things to different people. One that is considered heavy duty in the SCUT world would be considered lightweight when talking about larger tractors. Amazon has one listed that says that it is heavy duty, but then states that it handles up to 75 hp. My idea of heavy duty would be one designed to handle at least 100 hp, but that's just me.
 
Depends on what broke, did it stop engaging and driving the output side, or did it pull apart axially (front to back)? If it pulled apart front to back, it broke through poor maintenance of the PTO shafting on your implements. Those units are not designed to take the end thrust from your shaft not telescoping as the implement moves side to side and up and down. Also you need to give them a shot of grease EVERY time you use it.
