Overriding coupler same as slip clutch?

Ok, dumb question time.

My Jubilee has what I believe is called an overriding coupler (looks like what the local TSC Farm Supply sells). I am getting a 5' mounted rotary cutter and need to know if the overriding coupler does the same thing as a slip clutch? Also, I don't understand how the "ratchet" effect of the coupler works.

My Jubilee does not have the live pto option.

Can anybody educate me?

Please help.

Thanks in advance.

Hi Mark, not same. overriding coupler allows tractor pto to drive implement (bushhog) but will not allow the flywheel effect of the bushhog to drive the tractor. this would happen with older pto configerations. you could drive to a tree, push in on the clutch which disconnects the engine from the drive axle. but since the bushhog was rotating and directly connected to drive axle through pto, the tractor would keep going. very dangerous. overriding coupling elimates this effect. usually consist of pawls or balls that slip in one direction, wedge in in the other direction. usually is connected to tractor pto. now slip clutch is a type of clutch that limits the torque applied to the implement. usually consist of friction disk and springs that are somewhat adjustable. usually connected to the implement side of the pto shaft. for an older tractor both would be nice. for modern tractor, the limit clutch is nice. hope i have not muddied the waters.
