Push ring PTO coupling

[Fordfan1234]

Hi
I have a PTO with a ring which slides towards the tractor when the PTO shaft is placed on the end of the PTO. How do I get it on the tractor spline to the grove and take it off again at the end of use. The push pin PTO I have is a breeze in comparison. Cheers John N

They are all about the same. Pull the ring back, hold it in place, push the PTO shaft all the way forward onto the tractor/implement PTO stub, release the ring. The ring should slide forward and release the pin to engage the grove on the PTO shaft.

You might have to pull the PTO shaft forward/back a bit to ensure engagement.

I currently have the push pin type PTO shaft. I previously had the slip ring variety.

Lots of lube and patience is the answer.

Those ring type PTO couplers are a PITA. But the government says they're safer for us because you don't have the end of the locking pin spinning around when the PTO is running.

It's very difficult to PULL back on the ring while you PUSH on the knuckle to engage the spline. I have found that it helps if you engage the tip of the spline in the knuckle first (it will only go on about 1/4") then PULL the ring back as you keep the knuckle engaged, then PUSH the whole thing on as far as it goes, then PULL the knuckle back until the detent balls snap into the groove of the tractor shaft.

There is NO EASY WAY to connect this style of coupler.

As someone mentioned above you match up the splines first as they can be coupled 1/4” together before any locking device needs to be retracted. Unlike the other posters I love the locking ring type and hate the push pin type. What engineering idiot designed a pin with pounds of spring pressure on it that is only 1/4” in diameter? How about a decent sized button on the end........

Amen! I'll take the locking ring!

Lube can make coupling the female and male fittings easier.

I once used Fluid Film.

However, I have found any brand of spray DRY LUBE to work better for me.

WD-40 is too thin. I will assist coupling but burns/ drys out when shafts heat up. Removal is tough with WD-40.

True Dat!!!!! Especially as things age.

^^ I saw where this was headed the instant jeff posted that.

I have NO problem using WD-40, it works just fine for me...

I also MUCH prefer the button to the ring!

I use the method mcfarmall described...

Thank goodness no one has mentioned using K-Y Jelly!

I've always preferred the button style too. The ones I have used were large enough to push in easily. Does your new BB720X have a ring style?

Hey it's non-staining and will wash off very easy :thumbsup:

 

[Fordfan1234]

Thanks for the suggestion I will see if that will work for me tomorrow morning thanks John N

Yes, but if the front half of my old Woods hog, that has the button style "properly" fits, I'm going to slide it in,

and use it!

I was afraid of that, since I've read the ring style is the most used now. I just ordered my BB720X today.

either is better that the twist type

When you say hold the ring back. The only movement at the ring from its normal position was towards the tractor. Do I push the ring forward towards the tractor then push the pto assembly onto the tractor spline cheers John N

I bought a bush hog with one. I told the dealer when I bought the next one that it would be sent back if it didn't have the push pin on the yoke.

 

[vvanders]

Sell it.

Got one of those with our PTO generator. With the safety cowling it's physically impossible to install. Spend 30 minutes cussing at the thing and finally just used the PTO shaft from the flail mower instead.

One thing that hasn't been mentioned when you 'pull' the ring back is to use both hands... (after lubing both the PTO shaft & the coupling with a lanolin lubricant) I cradle the coupling in the palm of my hands, then 'pinch' the ring back between thumb a fingers...

Once I've got it sliding onto the shaft, I can release the ring either before or after I've advanced it regarding the PTO groove. You can hear & feel it lock into the groove.

Then it's just a matter on getting/cleaning all of the grease that has jumped onto your clothing... and then everything that you've brushed up against... which should take a few days. :laughing:
