Don't do it.

When I pull t-posts I use the 3ph not the loader bucket. I attach the chain to a rear blade and lift straight up. Either it will pull the post or stop the implement, but it won’t break anything if the attachment is centered on the blade.

One time I tried to pull a simple T post with the loader. Had the heavy box blade on the back and it lifted the rear off the ground.

One thing I have come to appreciate about a low-powered tractor without much hydraulic power, it is hard to tear anything up. The loader just runs out of power before bending anything or lifting the rear end.

I am usually telling myself “no” and hiring it out.

Really! the back lift on most tractors has double the lifting power of the FEL,

I started with tractors without FEL, so didn't get an early dose of bad practices.

A fence post only needs to pull out about 8 inches before it gets easy.

Turns out it was a steel post in concrete. How much I don't know but the clay soil here locks everything down when it is really wet and when it is really dry, like it is now. So you are trying to pull the post, the concrete, and all the hardened soil 3 ft around it.

Yep, a bit north of you but when it wet it's like quick sand when dry like concrete...

high lift farmer Jack is the way to go for this kind of stuff or like other said the 3 point.

Several years ago I was pulling old fence posts with the loader, which was fine for the line posts. Switched to the 3 point for the concreted corners and pulled a real bone-head move...
I threaded an old section of 9k climbing rope through the lower hitch arm mounts for the pull, and snapped off the 3 point arm case mounting point due to the force pulling the lower arms together. That ended up costing me $2k.

my go to is an old tire rim (the larger the better) without the tire on it. attach a chain to the post as low as you can, place a 2X10 on the ground put the rim down on its rounded side with the chain over it then attach the other end of the chain to the draw bar on the tractor and pull.

I was thinking about this method recently and wondering if you couldn't do the same backing the tractor rear wheel up to the post, Chaining up the post the draping the chain over the tractor tire then putting the rest of the chin under the tire, so moving forward would walk the chain pulling the post up. What think yee?
