HOW DO I REMOVE A SUPPORT PIVOT ROD

I didn't tear mine apart to see exactly what was in there (I was too cuss-ed ugly after changing it out I didn't care -- I was just glad to have something to sit on so I could drive the tractor!)

Basically there's a rubber bushing in the gap in the seat mount with two nuts or a single threaded tube embedded in it. The bolts that come in from the outside of the bracket on top of the tool box bite into the threads of those nuts or the threaded bushing (whichever) that's in there. The threads rust together and/or the rubber rots out, the nuts turn, and you can't break the threads loose. If they'd asked me to design the thing, I'd have embedded a straight tube for a bushing in the rubber leaving a rubber flange on each end, and driven a single bolt to push through and be tightened with a nut on the other end. But I wasn't alive, so I'll forgive them for not asking me.

The more I think about it, it acted more like a single threaded bushin inside. The more I twisted, one side or the other would turn in the thread and eventually come out, but that was of no use in getting the other side out, since the center was free to spin.

You may get some other good advice on how to get it apart, but I went at it like I described in the post below. It took some finaglin', but she came apart with the heads of the bolts ground off. Took some sweat, some colorful persuasive language and some patience but she came apart.

IIRC, the two bolts thread into nuts or someting else with a thread imbedded in the rubber bushing. The problem is probably that the rubber is shot and wont hold the thread in place as you try to back out the bolts, so ou're wrenching and getting nowhere.

I wound up grinding the heads off both bolts, then beating the shaft of the bolt back in as far as it would go. It took a little flexing (NOT bending, though that may be necessary) to nurse and wiggle the stub of one of the bolts out of the holes in the base, and lift the whole out.
