I have a King Kutter 6' bush hog. No slip clutch. The shear bolt has broken due to hitting something. After removing the snap ring, I cannot remove the PTO from the shaft and it has moved past the bolt hole. I assume part of the shear bolt is seizing the PTO. Any suggestions on how to remove the PTO to be able to install a new shear bolt?

Had the same problem a few years ago with the PTO drive shaft "stuck" on a sheared bolt.
This is the method that worked in that situation.

Rotate the PTO drive shaft so that the hole in the universal joint is on top.
Apply plenty of your favorite lubricant into the hole.
Using a long bar through the universal joint, hammer against the long bar.
Rotate the PTO drive shaft 180<sup>o</sup> and hammer against the long bar.
Repeat the process until the end of the universal joint clears the sheared bolt.
Hope this helps.

Can you push it in until the holes line up then drive the shear bolt
out. At least by going in you can lubricate the shaft.

it that might loosen it up

James, is that a Model T drive shaft? Square on one end and tapered on the other?

That drive shaft came with the rotary cutter.
It is a Corsicana 7ft cutter.
These cutters are not manufactured anymore, but we can still get some parts from the local New Holland dealer.

Maybe I did not make myself clear. The bar you are using to turn the pto shaft looks like a Model T driveshaft. One of the best prybars to have in the shop.

Might work as traditional said:
I bought an old post hole digger, I took the sheer bolt out on the gearbox to PTO shaft.
But, could not get the PTO shaft loose from the gearbox shaft.
So I took the old post hole digger out and started digging holes, sprayed the shaft
connection with penetrating oil.
After about four or five holes in that hard dirt, it finally broke loose an I was able
to get the PTO shaft off the gearbox shaft.
Note: I kept the safety snap ring in place!!!!!!!
If you try this, I would re install the safety snap ring, if it does come loose you do
not want it coming off an tearing up something else.
Good luck and stay safe.
Either this method or take the universal joint apart and pull it apart with a heavy duty gear puller.

You have "friction welded" the yoke to the shaft.
To fix it "right" you will need to cut the yoke off of the shaft, clean the fused metal off of the shaft and go back together with a new yoke.
Been there, done that, on a Farm King snowblower.

I have no idea when we acquired that bar.
My father worked at a steel mill and probably "rescued" it from a scrap pile headed for the smelter.
Also use it to turn the drive shaft on the balers to oil the drive chains.

Dj,
Not trying to get the cart before the horse, but when you get this all sorted out,
be sure to use the proper soft sheer bolts, when I sheer one off in my old hog, just
knock it out or many times they will fall out and insert a new one, they should be soft
bolts.
Sometimes when people borrow your stuff they put in hard bolts because they do not care
about your machine.
when you have to go after it wherever they leave it, it will be broken.
