There you go! If you can find a old style bumper jack. TSC has 'handymans', but dang, one of those bumper jacks would work just as good for that.Old fashioned car jack, and something to hook onto the post. That's what Dh did, and it worked.
I'd like to have one of those pullers but don't like spending $.
@Latestarter , I move my run with t-posts quite often, sometimes pull up easy, sometimes holy crap must catch a boulder. Wriggle/wiggle, bend and pull, ...
I now just use a crowbar with the sledge hammer I use to pound them in, to pry down (up) on on the bumps . Only goes up a inch or so at a time but easy. Pry pry pry, up up up, gets past the hard spot pretty easy.
