I had two long rows of vinyl fencing that bit the dust in Ida. Posts basically sheared off at ground level. Each post had a bag to bag and a half of concrete to secure it in place. Anyone know how to remove the concrete from the ground.....besides manually digging it up?

On one side, I plan to stagger the posts to fit in between the current blocks of cement, but I already did that on the other side (There was an older vinyl fence there when I purchased the property). Thinking I may need to remove some cement to make it work. Doing it manually is likely out of the question. I have about 20 posts. Any advice/thoughts are greatly appreciated.

Screw a large bolt into the remaining wood from the post. Get a hi-lift jack with a tripod attachment and attach a chain to the bolt and the jack. Jack the cement and posts out. 5-10 minutes per post and you are done. Then you have the hole all ready to go for your new fence as well.

Vinyl fence posts are hollow. Thanks for the idea, though.

Ok, then what about a small piece of flat bar that you can lower down and when you pull it wedges into the vinyl and pulls it out then when it’s out you can dislodge it and move on to the next one? I’ll make a sketch.

Can also substitute using a tractor front end loader in place of hi-lift Jack to do the lifting

Can you dig out a little bit and wrap the chain around the concrete?

Front end loader or back hoe....hook a strap around it, and lift....peice of cake. and worth the rental fee.

I had to replace a few fenceposts about three years ago after a storm. I dig one out but it took about 4 hours and was a mess. My neighbor has an old Ford tractor with a bush hog to mow his property. He came over with his tractor, exposed the first 6" of the concrete, wrapped a chain around it a couple of times, and then got on the tractor and pulled the remaining two posts in about 10 minutes (for the remaining 3).

Rent a piece of equipment! So much easier.

If you can do this, connect the chain to a truck, but run it over a tire on a rim to redirect the force.

All you have to do is wrap the chain with a slip hook around the concrete then. Same concept.

this works, but use a spare tire, slightly deflated for extra height. Also, Tie off the chain a few feet from the tire and connect the tie off to the tire, in case the chain snaps off the post it wont missile through your back window.

Make sure there is a steady base for the hi lift though otherwise your lift will sink once under pressure. I put a 2x4 under mine and it worked well

I built a tripod about 4' high

Used metal pipe with a big ubolt as an attachment point for a (heavy duty) come a long

position tripod over the concrete

wrap chain around the concrete using slip knot, you may need to dig around the concrete slightly to expose 1-2 inches to allow the chain to bite

connect chain to come a long

pull up slowly

About 1 min per hole

Move to next hole

if these post are the ones I'm thinking of a wooden 4x4 would fit perfectly into your existing vinyl 4x4s.

the vinyl post are really made to go over wooden 4x4s as a wrap.

Drop wooden post in and top with vinyl wraps.
could pour thin set to fill the void that that may be present.

Watch this video and start at about 3:20. He goes through his lessons learned on removing fence posts.

This guy’s channel is awesome, by the way. If anyone here is a woodworker or wants to learn from someone who started all on his own, I highly recommend it.

Edit: welp nevermind. With the posts gone this doesn’t help at all…

Well, there is at least one dumbass here, as evidenced by the 1 red arrow.
