I've got an overruning coupler and a slip clutch on my 5' hog, hooked up to an 8N Ford. From your description, it sounds like the same overruning coupler. Stiff as all get out new. Mine did not work at first either, but after it broke free the first time, it worked smoothly there after. I do not know of them being in different spring configurations, as that would serve no purpose. Just initial stiffness, perhaps due to rust as you suggested. Mine broke free in operation after a few tractor stops. Still stiff for the next few, and now just as free as can be (turns by hand quite easily). The addition of a slip clutch could cause a binding problem with length, but that is inherent with the specific shaft and such. If it's a problem, it's simple enough to trim the pto shaft on the impliment.
More a concern is where you mount it and how much flexing you get going. With the overruning coupler, you've already got two areas of wiggle up front (where the coupler attaches to the tractor, and where the impliment pto shaft attaches to the coupler. Adding a third one up there could create a problem with excessive flexing and wiggling. My slip clutch is mounted rigidly to flange on the gearbox of the bushhog itself, with the universal joint mounted to it. Far more stable that way.
