Patrick_g, I'm going to need a photo of your puller-gripper-thingy....can't seem to get a picture in my head...
John, I posted a drawing a while back.
It really isn't complicated. It is basically a short length of scrap pipe with a chain welded to it.
Hanging from the chain, the axis of the pipe is diagonal WRT the world. The pipe is like a wide wedding band. It will slip over a T-post by gravity but when you pull up on the chain it cocks the pipe which catches on the bumps on the T-post and lets you pull the post.
If you lower the FEL till the post starts to touch the ground a little and jiggle the FEL a bit and raise it a bit the T-Post falls out of the grabber and you are ready for the next one.
My pipe was a little larger diameter than I wanted so I welded some scrap steel inside the ID to close the hole down a little so it grabbed batter when I pulled up on it.
I haven't used it (or seen it) for a while and don't really know exactly where it is. It would only take a few minutes to make another one. I'm no artist but I'll try to make a sketch, scan it in and post it.
Here goes...
OK, I fond some previous scans so posting an old one and a new one. Both designs work. The one with the scrap plate grabs better (fewer missed attempts) but doesn't release quite as easily.
Note: These drawings are not all that good to scale. Make a prototype and watch how it works and then make a better one. NOt much to these but they do work.
The commercial post popper I have, the one that works manually like a jack has a little attachment that grabs the post. You could duplicate that attachment and have a post puller that would work on flat posts AND T-posts.
