How do I get this PTO bolt off?

[Farmerford]

Mike has it exactly right. If the bolt is partially sheared as much as it appears, you are likely to have to drill out the parts of the bolt within the yoke collar. Don't drill all the way through because the collar is probably offset enough from the shaft that the holes in the collar and shaft don't line up and you will enlarge the hole in the shaft (not a disaster, but best to avoid).
If you have to drill the bolt out, here are a few hints. Very carefully mark the center of the end of the bolt with a center punch. Then drill the bolt to the depth of the collar and just a bit more with progressively larger bits. Start with 3/16 or 1/4, follow with a 3/8, and finish up with a 1/2. If you are careful (and lucky), only the middle part of the bolt within the shaft will be left, perhaps with thin slivers around parts of the holes in the collar. That should let you block the blades (to keep the shaft from turning) and turn the collar with a pipe wrench to align the holes and drive the remaining pin from the shaft with a pin punch. If you are real lucky with your drilling the collar may pull right off (after removing the lock ring as Mike pointed out).

The safety police will protest, but the first thing I would do is cut that plastic shield off the universal joint. It will make the work much easier.

The shear bolt is partially sheared. Get the plastic cover out of the way, support the shaft solidly from below and rap it as hard as necessary with a hammer and punch, (if necessary).

Are you sure you need to take out the shear pin to replace the zerk? Start with Normde2001's suggestion and remove the plastic collar. The collar should slide up the shaft after releasing it. That should give you access to the zerk.

I removed the shear pin this morning by tapping it out with a hammer. It was indeed partially sheared and bent.

I then had unencumbered access to the defective grease zerk and changed that out.

Everything is now greased, reassembled, new shear pin in place, and ready to go! Thanks to everyone for the suggestions. Time to go cut some weeds!

I see you already have fixed the problem by the time I read and got to post, so you may not even see this. Anytime your hitting one object with a hammer, wear SAFETY GLASSES.
