Brendan,
I don't know what kind of sound you are talking about, but I guess the first question has to be, does the clutch disengage before the pedal stops moving? Are you able to shift the transmission into gear with the engine running? If you have one inch of free play, then I think the only thing that stops the clutch rod is the pressure plate fingers bottoming out. Does anyone with more experience understand what is going on here? I guess a little more info would be helpful.

Brendan, remove the clutch housing hand hole cover on the bottom of the torque tube, take a flashlight and get a better idea of what is going on inside, without seeing it in person it is hard to troubleshoot your problem. There are some key adjustments that must be in place as Glenn mentioned, but I am wondering how much of the graphite release bearing surface you have left held in place by the retainer.

Well all it will do is when you push the petal in only a inch before you hear a grinding sound kinda. next time im near it ill take a look first thing!

Visually check the thickness of the graphite bearing as it protrudes from the retainer as shown in this photo from TM Tractor:

Sounds like you have no bearing left and the cast bearing housing is rubbing on the pressure plate fingers.

As cubguy stated, look in the handhole and see if all three fingers are equal distance from the release bearing.Does the clutch pedal seem to "pulsate" when you hear the noise?

Yes i can only push it in so far before it sounds like its grinding. About an inch or so.

I would guess the fingers are out of adjustment. Possibly a stripped adjustment stud. It shoul dbe obvious once you look up in the hole though. If you have doubts, take a picture of what you see in the hole and we will help as best we can.

I had a similar problem a while back, and it turned out the fingers of the clutch were out of adjustment. The terrible noise actually began after I had adjusted the pedal free-play for the recommended 1", and the TOB carrier began hitting the tops of the adjustment bolts before the TOB itself hit the clutch fingers. It was really a gawd-awful noise! After I adjusted the clutch, I still had to make the free-play a bit more than 1".

Good luck!

How did the adjustment of the pressure plate fingers appear when you looked up inside? How much wear did you have left on the throw out bearing?

This how-to by Jeff Silvey will give you a good start as to what to look for and how to adjust. The Cubs could have come with one of two style clutches--Rockford or Auburn--but this will help you understand the basics of how it works and the adjustment process.
