you could try a long eye bolt and pulling them or getting auger bit and drilling them. Hard to say without seeing it.

I used and auger bit to drill it out and then pry bars to break it apart and pull it out. I found vacuuming out the wood chips helps. It was a time consuming task, but it probably depends on how rotten yours is. Another option is a tree stump remover that you pour into pre drilled holes and set it on fire. No big flames but it gradually burns out the stump. Word of caution, don't do it if its near your home or a gas line.

Biggest longest drill bit you can find. Drill as many holes as deep as you can. Use a pry bar to break up the post, and fish the pieces out of the hole.

I have driven a studded steel post into the broken post and pulled it out. Doesn't work every time though.

Long auger bit,bring it out frequently to clean hole so you don't get the bit stuck.use 1 inch or bigger.make sure to get one that you can put on an extension,because you don't know how deep in is.

Instead of putting the pipe into the hole can you weld a plate to the end of the pipe and anchored it to the slab? Just cut the wood off flush.

Can you screw a very large eye bolt in it and pull it out with the hoist on a tractor?
