My TC33D does not have a "one way clutch" (by which I assume you mean an over-running clutch, also known as a sprag clutch). Those are usually not built into the tractor, they are something you add to the PTO shaft.
Thanks for the reply, John. My tractor does in fact have the one way clutch, It is in the intermediate PTO shaft. Some of the TC series do not have them. Wish mine did not as it looks like a major pain to replace. Hence my post. Thanks again.
