over running clutch

[Anonymous-0]

I am going to run a thresher with a horse powered sweep power. Since the thresher cylinder is essentially a flywheel I need an over running clutch so that when the horses stop the machine wont drive the sweep arms into the back legs of the horses.
I was wondering if an old silage cutter or haybine would have an overrunning clutch on it I could use.
Does anyone have a good suggestion?

Thanks

how bout an overrunning clutch for the 540 rpm pto? farm and fleet sells em for about 50-60 dollars. i have them on my m's for the bush hog. they release very easy, shouldnt be hard to splice one in to the pto shaft.

New holland small square balers have a simple over running in the driveline just in front of the flywheel. Would be very easy to adapt to your application. There are many of these units in scrap piles in dealer lots etc.
