Fence Posts, upside down or not?

[tallyho8]

The fences I am putting up are either barb wire or field fence and they are in the back pastures so they don't have to be perfectly straight for aesthetics as they are surrounded by woods.

Almost all the old fence posts that I am removing that are from 50 to 75 years old, all seem to be broken or rotten right at the ground level and the part above and below ground is in decent shape.

We don't have any frost here to worry about and if the poles do work their way up a few inches over time, it wouldn't be hard for me to go along the fence line and push them back down a little with my fel every few years.

If I was digging a larger hole and filling with concrete I would put the large end down but since I am driving them like a pile driver does, I believe that it is compressing the soil around the poles making them tighter than they would be if I put them the other way and tried to tamp dirt down around them.

One thing for sure, it's a lot easier to do it this way.

If the posts are being driven rather than planted...they will drive much easier stump end up...also less chance of splitting...

I used to contract with a pile driver and all wood piles were driven "top down"

Do you sharpen the end before driving it down? It would be unheard of here to do it any other way. There are machines in use here that peels the post and as it finishes the operator lifts it and puts a pencil point on the wide end. They are pushed in and then after a few months and a few rains the ground settles back around to hold them tight.

I curious as to what technique you use to push the post down with out bending the bucket. How exactly do you do this?

My Kubota L4400 has a very sturdy bucket but I also fill the bucket with dirt to give it a lot of weight to force the post down. Also, as stated in post #1, I dig a hole first a little smaller than the post with my post hole digger making it easier than just pounding the post into the ground.

The big end goes down. It's digging holes, not science or art. Don't put more than eight inches of dirt before compacting. Don't use green colored posts. They are junk! Get black, creosote coated, ones. I've installed thousands. The key to success is product and compaction.

We do much the same, the only place they'll rot off is just where the ground level is.

As a retired Telephone Outside Plant Engineer I couldn't help but get a chuckle from the comment about never seeing a power pole up-side-down. I just wish I'd thought of specifying one that way on a job so I could hear what the Line Crew foreman would say. They have a very colorful way of asking wtf???

Power poles are much taller, and the fat end is much stronger. I've written orders to replace poles hit by cars where the pole broke at the top where the wires were connected and not at the bottom where they were hit.

Productivity would be diminished since it would take longer to drill holes, and longer thru-bolts would be required.

Poles only rot at the ground line. In a lot of wet areas a chemical wrap "bandage" is placed on a pole at the ground line to ****** rotting. I've often wondered it that sort of thing would be worth while for a farm. Perhaps if you could "borrow" them from the phone or power company. ;o)

...Poles only rot at the ground line....

Ever been to a marina?...all the pilings (telephone poles) are fat end up...and usually domed off and painted on top...many are capped with copper...

Next time you're on the interstate...check out the wooden DOT fence posts..all have aluminum caps...

Wood is most susceptible from the end-grain

You are right, they rot at the top as well. But they seldom fail because of that rot.
