Yeah, that's the same response I got when I was looking for the FH connection part. Fortunately, I was able to get that part welded at a Cubfest. Still looking for the PTO shield front half.

Sorry, I misunderstood. It originally sounded like the yoke to the gear box on the mower deck itself is where the problem is, which is why I thought you could just weld them together. Upon re-reading again, I see that you are referring to the yoke on the PTO drive shaft wearing out the splines on the PTO shaft on the tractor.

In that case, here's a fairly simple repair. Pick up a PTO adapter, to get the splines on the Cub PTO up to a standard 540-rpm PTO size. It looks like these are running about $30

Then go to Tractor Supply and pick up a standard PTO yoke adapter. It looks like these are around $50:

Replace the old yoke from your PTO shaft with the new one from Tractor Supply, and you should be in business.

He's already found the adaptor, just needs to chase down a standard yoke that will adapt to his shaft.

I called Messicks about the RM42CF drive shaft and asked about splined yoke, part #23982 and was told it is available as well as the attachment kit assy for the driveshaft shield (#7 in the picture). If yours is the same, you could probably change it at the u joint and have a new assembly. Picture attachment has the information.

Thanks all - I'm going to go with the PTO adapter that you found "git. I found it last night too! I'm going to go a different route and just have it bored into the current yoke rather than buy a new one and try to fit it to the shaft. Might end up a little bit cheaper in the long run. We'll see about that. I thought that potentially changing the rotational orientation of the u-joint seems a bit more risky than modifying the current yoke/joint.

Alright - little update and a question too.

Was able to have the PTO adapter bored and welded into place on the old female u-joint end of the mower drive assembly. While working on this, I also decided to replace my old PTO shaft since the worn splines were what caused the u-joint to burn up in the first place.

I'm still a little confused about what needs to be done to get the PTO lever to engage properly. I assume that the pin at the end of the lever needs to fall between the two grooves in the shift collar while also being sure to get the shaft lined up with the splines of the transmission shaft? Is there anything else to look out for while I'm attempting this? Any words of advice?

Is there any possibility of the transmission shaft/bushing moving forward toward the front of the tractor? I went to install the PTO initially and did not line up the lever properly and screwed down the rear plate under a bit of pressure. Realized afterward when the shaft itself wasn't turning at all that I had done something wrong. Hopefully didn't hurt the bushing or the transmission shaft?

What's best way of getting photos up here to share machine job on u-joint with those who have asked??

Thanks in advance for your help!

Big thanks to Ed for coming out to lend a hand setting the PTO shaft and lever into place... took less than 5 minutes after he showed up.

thanks Ed!
