Hydraulic Top / 3pt Hitch removal

I'm working on getting into the top cover of the rear hydraulics (position lever not working (very hard to move), though 3pt arms go up and hold).

I've gotten pretty far by starting to remove sheet metal, seat, and coverings, now disconnecting 3pt. hitch arms and center link i've run 3 questions.

1. Bolt on left side 3pt arm won't remove, head broke off bolt, I removed the PIN holding the knuckle of it, so I can "saw" through it later, any ideas ? Rever to pictures.
2. The center link came off easy, but than there were 3 pins holding the "thing" it pivots on, top / bottom pin came out easy, the middle one will not move at all, it does "pivot" on it, but i hammered on it a bit (big hammer) and no movement? Any ideas ? see pictures.
3. on to removing the top of the hydraulic lid thingy, do I have to remove the remote hydraulics ? They work fine, but it looks like I will have a hard time getting to the other stuff with that on there, see pictures.

(i'm going to fix this thing !)
( dealer said he'd fix for 1k to 2.5k, but would take him 4-6 weeks to get too, so hoping I can do myself).

Any ideas help is appreciated.

Looks to be a 4200. Top link arm can stay. Looks to be enough room to take sawsall cut bolt off. The remote valve and plate can stay.
 
That's what I was thinking too, hack saw off the bolt, leave top link in-place and try to remove top lid with remote hydraulics on.

Thanks for affirming, i'll proceed (with caution !).

The remote valve is different on a row crop model, not sure about the valve but I think that plate it's piped to will have to come off, pretty sure there's a bolt under it the holds the lift top on.
If the valve is hard piped to the plate it'll all have to come off
 
This doesn't help, but you just caused me to think about using a cylinder for the top link, and that has to do with your problem. With a mechanical link you can rotate the link and change the setting till it's free to unpin. On the hydraulic that seems to be much harder to find the sweet spot to undo the pin. If you are a limit it could be what you are experiencing where with a mechanical you just get out a pipe wrench and unscrew it.
