H PTO Drive Removal

My question is how do I remove that lowest shaft? I found the retainer ring on the back end of the shaft where the actulal PTO shaft mates, but on the front of that shaft is a bearing with three bolts. I remove the bolts, but nothing moves. The front of the shaft has a large slot where a short coupling can be removed. Do I try and drive that entire lower shaft forward (toward the front of the engine)?

I read in an IT manual to "remove the nut" on the front of the shaft, but the only "nut" I have found up there is the one working on it.

Thanks in advance for the help. JK

Kirk is right about the nut. Here's the IH Blue Ribbon book paragraph about taking out the lower shaft says:
Does that make any more sense than the IT? I've found that those two books often fill in gaps for each other.

Thanks all of you for the info. I did check some gear prices and I think I will look for a new rear instead of replacing parts.

I also noticed the cast housing for the final differential bearings are broke. When you use the jacking bolts on them, whoever worked on it before me must not have removed the bull gears first. Both of them are boken (they still hold the bearings though).

I am going to take that bottom shaft out now that I know how. It is not going to whup me.
