PTO Connectors

[dooleysm]

I'll try to explain this as best as I can and see if anyone can figure out my problem and offer some advice.

I've got an old post hole digger my dad sold me from the cemetery where he works. He's worked there for 30 years and says they've never used it since he's been there. We went to use it last fall to dig some fence post holes and ran into this problem. The PTO shaft coming out of my L3000 Kubota was too big to fit into the female side of the PHD's PTO connector.

After driving all over town we found an adapter that has a 1 3/8" female side and a 1 1/8" male side. This allowed me to hook the PHD to my tractor and dig the few holes I needed to complete my dog pen.

The problem is, the female side of the adapter that I bought has a hole drilled through that expects to mate up with a similar hole drilled through the male PTO shaft. You can then put a bolt through there to keep both sides held together. My Kubota PTO shaft doesn't have a hole drilled through it (I'm guessing this is an older method) and all my other attachments have the collar release or a push button release that keeps the attachment's PTO engaged to the tractor's PTO.

So, every time I drill a hole, the PTO stays engaged while I'm going down, but then when I lift the PHD out of the hole, the PTO slides off the tractor. Big hassle.

So, does anyone know of an adapter that I could get to keep things happy, or will I have to replace the 1 1/8" female connector on the PHD's PTO shaft? If I do have to replace, is that something I can do myself easily?

Thanks guys!

The easiest would probably be replace the end on the PHD PTO shaft. Basically the same as replacing the universal joints on an automobiles drive shaft.

Shame on Kubota for not including the pto standard hole. That is terrible of them, normally I think a lot of the Orange company.

You could have a machinest drill the pto shaft on your tractor.

I'm sure there are adaptors that are spring-locked, & not pinned on. Can't list one off the top of my head, but I'm sure you will find one.

I agree with rambler.. I think it is pretty chincy of a tractor comapny not provideing that standarized hole that has been around since the po came out practically.

Here's what I would do.. that that 1 3/8 female to 1 1/8 male adapter.. it has the hole on the female sleave side... tap some threads into that hole, and then use a bolt.. or preferably, a recess allan head set screw.. screw it in till flush on the inside... now.. slide it on.. tighten it down and away you go. I have a seeder with a smooth coupling that relies solely on 2recessed allan headed set screws to hold it to the pto shaft... have never had an issue with it. I simply carry that allan wrench in my tractor tool box...

This way you are not drilling your tractor pto, and you are only modifying a ? 15$ part.. and not that vintage ? mid 50's auger with the neat 1 1/8 yoke on it that a collector may want .. intact, one day...

You will only be out the cost of the set screw(s) and the time it takes you to tap some threads into it.. 5$ and 15 minutes?.. way better than tring to drill the shaft on the tractor and hope you get it true and straight.. or vs pulling the shaft and then replacing seals and oil and gaskets, and paying a machine shop to do it.. etc..

Check Agri-Supply - I believe they have quick release PTO adapters that don't use the bolt.

To take Soundguys idea one step further. Slide your adapter on your PTO shaft, and spot drill your PTO shaft to create a slight recess, then as Soundguy said, tap that hole and use a nylock setscrew. That way it wont come off and the nylock shouldnt loosen up /forums/images/graemlins/grin.gif

Thanks for the advice guys. I checked agri-supply and it appears the quick release adapters they have are for 6 spline to 21 spline and vice versa. No 6 spline to 6 spline adapters.

I guess I'll try tapping the adapter I have like Soundguy said. It was a $15 part at Rural King. I really didn't like the idea of drilling through the tractor's PTO shaft.

I guess most other tractors must have that hole in the PTO shaft or else everybody else is using attachments with the quick release PTO coupler. It seems to me this should be a more common problem that someone would have come up with a widely available adapter. I've looked all over the internet and talked to several dealers and none have had any.

Yes, all the PTO shafts now have the groove in the OD for the quick release. Sounds like you got it under control /forums/images/graemlins/grin.gif

My New Hollands (TC45DA) pto shaft is just like your Kubotas, it has no hole for a pin type of coupling. I thought this was kind of weird because growing up I was used to old Fords that had the hole. I wonder if all newer tractors are going to this type of shaft?

My 2002 7610s has the hole....??
