It's just a truck bed extension stuck inside the hoist it was hanging above the hoist were I bought it. I put the two together in my mind right there in the store.
The yellow ends are out of my jack stands.

Use a jack to pull the pole out of the ground.
I have a Hi-Lift jack, also called a farm jack, that I use to pull large fence posts out with, and it works so easy I would think it would pull that pole out. Just bolt a short 2x4 to the pole, lay a 2x6 on the ground and jack away. The jack has a 36" handle so either the base of the jack will go into the ground or the pole will come out.
