Removing concrete anchor bolts

Can anyone on here give me some advice as how to remove anchor bolts from concrete?
I am fitting a new fence post and need to remove the old fitting and bolts as the post is split and rotting away but the anchor fittings are stuck in the ground and will not budge. As you see, the end of the bolt is splayed out once is goes into the ground, causing it to fix rigid.

My last resort is to drill them out and make a hole to set the new post in cement instead, but I'd rather not.

Thanks.

Can you not attack the rotting post?

Are the nuts visible ?
Can't you undo them after a good over night soaking in WD 40 ?

I suspect they might turn anyway, along with the part in the ground.

Next.......try whacking them in, and knocking them sideways until they loosen a bit......then a nailbar in the threads might lift it.

There is a retaining wire ring holding the parts that spread the fixing in the ground, once that loosens the bolt will fall out...................give it some welly side to side.

Why not just replace the post?

Could be rusted and holed ?

ME first .... I am WOMAN and we has common sense

Do not set a wooden post in cement. When it rots at the base you will have even more problems.

Use an angle grinder and cut them off

Apologies ... I failed to appreciate that the metal wotsit is knackered.

Any good at welding?
