Posthole Digger PTO Shaft Question......

[Dave M7040]

Dave,
We had to remove the spring pin so, someone didn't have to push it in while it was chained to a stump to pull it off. But I can tell you that way before the ball bearings get to where they seat, it is extremely hard to get on within the first 1/2" after inserting it, it becomes to hard to do with only your hands.

Clearly something is not correct.
As a test, why not go to somewhere like TSC and buy a yoke and see if a new one will go on your pto shaft easily before you worry about it being the correct yoke for your shaft.
Then just return it saying it does not fit or whatever....

If it goes on easily, then find the correct one but..... if it does not, now you know something is off with the splines on your pto. Perhaps a bit of a twist caused by the old yoke?
