After jacking a couple posts out of the ground, we decided to give this method a try.
1. Probably would be a good idea to lay a piece of carpet or tarp over the chain. However, there was rarely much force that needed to be applied. Any time there was, I backed away from the post. I did not install these posts. I just needed to remove them.
2. We shouldn’t have used the tow ball to pull from. Again, never came close to the tow capacity of the ball, but probably still should have avoided it.
3. For those of you that cannot get a truck close to your work area, I guess you will have to find a different method.
