I use an old pair of ice block grabbers, the kind that pinch tighter when you pull on it, and a chain attached to the two handles. I then use whatever power at hand (vehicle, tractor, winch ect) to pull them out. Then there’s what I always call the ‘Egyptian’ method which is just rolling the log the long way on short pieces of pipe or small logs, continuously taking the ones from the back and putting them in front.
