</font><font color="blue" class="small">( Northern Tools sells a metal post puller for fairly cheap. I bought one about 2 years ago and use it often. It works well and does not bend the posts. )</font>
Those things rock!
I used to buy the cheap t-poles for my garden because I always damaged them getting them out. Then I found two tools. A t-pole driver and the t-pole puller. I have not damaged a t-pole since. Not the expensive ones, not the cheap ones. Nor have I had to dig for an hour to get the broken part out from below ground so I would not run over it with the tiller next time I did that part of the ground. I have used the same cheap t-poles for my beans for the past 2-3 years.
I can see how you might do it with the FEL, but I can probably pull 6 with the dirt cheap tool designed to do the job properly in the time those guys do one, and I can guarentee I won't bend it.
ymmv.
