Sounds like an ideal case for a self gripping puller based around a two spring loaded quadrants, like two giant opposed STEIN adjustable rope grabs. Drop them over the post and lower till the cams are apart, then lift so they self grip, pull the post. To eject crowd forward and lower simultaneously.

 

I dit think you would need the spring pieces or  anything  just a c shape of the thick metal welded to a headstock mount with the inner c  slightly bigger than the posts 

Drive up to post so the c shape is nextto post turn wheel so post enters the c crowd back and the post be gripped lift post out ground uncrowd and post will become loose 

 

Like how a formwork pin puller works
