My 80's vintage Ariens GT17 has a custom fabricated loader on it. The pump is powered off the front PTO shaft. This past weekend, the coupling between the pump and the PTO shaft snapped. It appears this coupling was a custom made piece that was clearly insufficient to handle the load, so now I'm trying to engineer a more durable solution.
What I would really like to do is just use a universal joint. It will require that I space the pump out a little farther, but I think no matter what I do I'm going to have to change the pump mount in some way or another.
The problem I'm having is figuring out how to go from a 15 spline male PTO shaft on the Ariens to a 3/4" keyed shaft on the pump. Here is where Bolens comes in. My tube frames all have a 6 spline shaft, but I think the large frames used the same 15 spline as Ariens. Does anyone know if Bolens ever had a yoke with a 3/4" keyed shaft to power some other attachment? If they did, it would sure save me a lot of trouble getting something custom welded.
If no such yoke is available, I'm open to suggestions for any other option to connect these two shafts.

Hopefully someone can help you out soon

In the mean time, I think I may be on to a source for the yokes. It looks like Weasler may make a 15 spline and a 3/4" keyed yoke that fit together. I'd rather go this route because I like off the shelf parts that I can buy again when I break the next one

I installed the rototiller on the 800 yesterday, and what did I find on the end of the driveshaft? That's right, a 3/4" keyed yoke. I don't know why I didn't think of it sooner. Anybody got a spare lying around? ;-)
That same yoke should be found on all tube-frame mower decks and snowblower attachments where they attach to the right-angle gearboxes.

Other sites offer adaptors that might be better suited to your purpose but I didn't search too long. Good luck!
