I think it gets called a clutch as it essentially clutches int he opposite direction, or when the implement overspeeds the tractor.. IE a 1-way clutch or ratchet. to save confusion from the newbies with the differences in that an a slip clutch.. the 'coupler' term seems safer.. to me anyway..

Just to complicate this discussion, my MF-124 baler has a conventional slip clutch (like you find on brush hogs) along with a sprag clutch that's built into the slip clutch. The sprag is a one-way clutch that only transmits torque in one rotation direction. In the opposite direction of rotation, the sprag free-wheels.

Yes, that is how I remember it on the MF balers. A baler sure could supply a good amount of inertia if it was allowed to.

sounds like a slip and over running all together in one.

my IH belly mower on my 66 cub has a built in orc in the mower drive pulley at the hub for the blades...

Flywheel effect..........have you see a tractor running into your car and the operator can not stop the tractor intime ? That is without a ORC !

I'm looking at old tractors in the 20 - 30 HP range and have been receiving advice in another thread. (Ford vs. Case)

I've gained a new perspective in regards to LPTO, however I am receiving some interesting information from sellers and tractors. I've been looking to confirm whether tractors had the overrunning clutch, and have noticed others identify a slip clutch.

Can you help me understand if these are the same thing? I'm gleaning that I can add a $60 slip clutch to any tractor's PTO. Is the "over-running clutch" a factory feature of the same intention?

I'm looking at a lot of late 40, early 50 Fords and other makes, but trying to stay under 3K. Not finding many of the later Fords (861) with Live PTO, but if I can add the slip clutch for the same effect, it opens up many options.

Thanks in advance.

For under $3000 you can find a tractor with live pto, a real drawbar , working brakes , live hydraulics and it's less liable to roll or flip than a N series Ford.

N series fords are no more prone to tip, roll or flip than any other brand with similar layout.

Its usually the moron driving that causes problems

Why are so many N series Fords upside down on top of their drivers?

Like the previous poster said, the moron driving. Usually trying to pull a heavy load with the three point hitch rather than the lower drawbar.

Many of those N's never even had a drawbar.

Moron drivers.

Given that most small 4 wheeled tractors with a 3pt hitch and hp rating from 25-40 and similar weight range perform practical identical regardless of paint color or name badge.

Since you are singling out ford, it signals that you are just hating on fords, or dont understand the dynamics of the problem, or both.
