I have done a few strange things related to farming in my life, and today was actually the second time I have had to reacquire a
fence. But the truth of the matter is, I have put fences in the wrong spot and had to move some on occasion too, so while I have spent several posts on how to put in a functioning NEW
fence, I never actually helped fellow Permiculturists on how to redo a fence that needs to be moved.
I use Page Wire fences with barbed staples so it is one of the trickiest to take down in a state that can be reused later just as if it was new. But these techniques would also apply to barb wire fences and barbless cable fences as well.
The trick is knowing two things: (1) even with purpose built
staple pullers, it takes FOREVER to pull a staple and in the number driven into the fence posts to hold the wire up, it is not even worth trying to pull them. (2) As great as it would be, and as simple as it sounds, leaving the posts stapled to the fence posts and then just driving them in the ground in the new location is impossible. The fence will not be taunt, and the posts will go in crooked, and it just will not work.
So knowing you cannot pull the staples out of the posts, yet knowing the posts have to be removed from the wire, the fastest, cheapest method is to use a 5 inch angle grinder with a metal cut off wheel. With the wheel you can cut the staple off from around the wire and pull it free. If you are careful, you will not cut the fencing wire; just the staple. If you do on occasion, it is no big deal on the field wires, but at ALL COSTS, do NOT cut the top and bottom wires on Page Wire fencing as that is your tension wires. Feel free to cut into the post however to get the staple cut.
I usually pull the posts out of the ground and get the fence, wire and posts to lay flat on the ground to do all this, often rolling up big lengths of it so that once freed, I have big lengths of uncut wire. If you cannot transport the wire home where you have electricity (or live off grid) I often put my generator into the
bucket of my
tractor, use an extension cord and cut staples free of the wire that way in a field situation. As for the metal cut off wheels, they go a very long time. I did a 10 acre field repossesion with 3 cut off wheels at $3.99/wheel. Considering a single fence post costs that, it is worthwhile to do.
Is it worth it overall?
I think so. A new roll of wire costs $179 for 330 linear feet, and posts are $4 per post. It took me two days of labor to pull, and reinstall that repossed fence, but with less than $10 in fuel costs and a few cut-off wheels, for less than $30 I got 10 acres fenced in. And since the fence was 7 years old, and has a lifespan of 30 years, 2 days of labor is worth 23 years of fence I think.
So if you find yourself needing to move a permanent fence, rest assured that you now have some tricks to make it easier.
