The drive shaft I bought from KK say's heavy shear pin (or somthin like that) on the plastic protector. I have a slip clutch on my woods 6' cutter. Am I screwed? Is this normal to have that.? I can not look at it anymore (its 300 miles away) I had only enough time to unwrap the package today and did not look into it any further. Any one here can school me? Whats the difference if any? Does the shear pin protection come with all drive shafts and the difference is that with my slip clutch, that is added at the end? In other words, does the slip clutch on all cutters have a drive shaft with a shear pin in it?

I addressed that very thing in your other thread, which apparently didn't seem important to you at the time. There are two basic kinds of PTO driveline protection; shear pin (good with the right size and grade bolt), and slip clutch (better).
But then it gets a little more complicated. Some slip clutches mate with a round transmission input shaft. Some folks mistake the bolt that holds the slip clutch to the round shaft as a shear bolt too. It's not. That bolt should be stronger than the slip clutch itself, so that it's still holding as the clutch slips. It's the bolt that actually causes the transmission to turn.
The other kind of slip clutch mates with splined transmission input shafts. They too bolt - but - obviously there won't be any shear pin action because of the splines. In this case the bolt merely keeps the clutch from sliding forward and coming off the shaft. It's the splines that do the turning.
Then there are add-on slip clutches that are splined on the input end to actually mate with a conventional PTO shaft. They could be either smooth or splined on the output end.
So what we need to know now, is how you plan to mate the new PTO shaft with your existing slip clutch.

Reason it was not important was because it was already ordered LOL! I admited I have my head up my ass when I told them I had a KK kutter. My problem stems from not being able to look at this right now and I need to plan ahead for my next trip up to my other house. No internet there to help me. Ive been searching for information on these two name brands and its like finding needles in hay stacks. Sure I can do a general search and get a general idea. I have basic knowlege of how it goes and how it works (slip clutch).
Im having a hard time visualing what we're taliking about. Maybe a trip to the local dealer is in store for me?
Greg, I appreciate your input, was not B-slapping you by giving you the impression that what you said was not important. Just was not getting the info I needed to visualize it and was gettin frusterated! I know its not complicated but am having a hard time (and its pissing me off I oreded the wrong company's equipment)
Thanks tom ....

I realize this is a long shot, but I'm in SE Minnesota right now. I'll be taking I90 through Wisconsin on the way back to KY later. Any chance your location is not too far off that corridor? If yes, I might be able to stop by and take a first hand look at your situation.

Tom, first things first, you need to know, or remember, the style of slip clutch you have.
Generally speaking they have either a smooth or splined socket that goes over the input shaft of the gearbox on your cutter. The other end will have a means to attach it to the drive shaft, that will be either another shaft usually, and again, either smooth or splined, or the 'ears' of a half a U-joint.
In order to mate the cutter to the clutch to the drive shaft they must all be of the proper type. Given that all you are doing is swapping out the shaft itself, we'll leave out the gear box to clutch part since we already know it was mated and therefore the same.
Now, do you remember whether your slip clutch was joined to the drive shaft by a U-joint or shaft to socket?
Best of luck. ....

Thanks but I am in the Northern part of Wisconsin, north of Eau Claire.
I just found out that I will have a whole day to myself as my bride dont want me helping (or anywhere near) the girls while they are primping her dorm room. Seems they think I wouldnt have any patience? Hmm Magine that??? While I have field work to do, ya think?
This will free up my schedual enough to drive to location that has parts if I need them. I did not think I would have this kind of extra time early in the week but now its looking better. Its hell trying to remember something you only look at 4-5 times a year (brush cutter, not the wife!)

Me thinks it was not the u-joint. I do have a u-joint on the end I busted up though (tractor side). I will take pics and post my stupidity after next week. Thanks ....
