I posted yesterday about removing rotted off posts in a pole barn garage. We started out trying the lag bolt screwed into the remaining posts and worked pretty well. Most came right out but a few were stubborn or pretty soft. Only had to dig down on two of them then got them leaned out away from the concrete and tied a chain around them to get them out. Took about two hours to get 14 posts out so not too bad. Thanks for all the suggestions.
