I tore down an old shed last year that was built on 8 4x4's sunk 2
feet into the ground with no concrete. But the soil around here is
heavy clay, and the earth had a death grip on those posts: a four-ton
hydraulic floor jack and tow chain failed to do the job.
What finally worked for me was to dig a small trench around each post,
and let the garden hose run slowly for about an hour on each post.
Then rock the post back and forth, and pull the sucker out by hand.

I pulled about a dozen 4X4 posts in my yard using a "farm jack" which
is kind of a super-heavy-duty bumper jack. If I didn't already own
one, I believe a regular bumper jack would have worked OK. Instead of
a chain I used a couple big C clamps and clamped a 2X4 block about 8"
long to the posts, and then put the jack against the block. If the
jack isn't powerful enough, soaking the ground around the post may
help. Put the base of the jack on a piece of 2X10 or whatever to
distribute the load and keep it from sinking into the ground.

Done it many times and it works great; just remember to set the jack on
a concrete block, paver, or scrap of 3/4 plywood.
It's kind of embarassing when the post doesn't move and you just jack
the jack into the ground(done that too)<g>

they don't need concrete in some rocky soils in some climates.
your particular post may vary from the others. the specifications of
the job may have been selected by the previous homeowner or local
permit office.
