Its a slip clutch....not an overrunning clutch.......
it has bolts and springs, which are adjusted somehow and also has disc in between......
Overrunning clutches are for older tractors, which did not have live power, or independent pto's.....they kept the tractor from being pushed if brush hog got in a bind.....a safety device....I'm sure someone else can explain it better than myself.....
From info on this thread,I have shortened the pto shaft, filled gear box, tightened the gearbox..loosened the clutch so that it slips...
I now have the bolt shearing business reduced, still shearing them but not as fequent, also going to raise the rear of brushhog and also repair tailwheel .....(after I get forge going)...may rebore the the holes in the pto shaft and install a larger bolt..
So I do want to thank everyone for their input, I've never seen a manual on a slip clutch or a brushhog....just bought used ones and started beating and flelling?....thanks to you folks, I now know how to brushhog......Mike

Yes sir,

I know what it is/does..........I was just wondering if you did...............I had one on my Ford 8N, which I sold a few years ago............I now have a Yanmar YM2000 and it has an over-running clutch...............My Mahindra 485 D.I. has live pto, therefore it does not have one...............
