We feel that you can drive a PasturePro post anywhere that you can a steel t-post. A standard manual post driver is all you need. A pilot driver does come in handy when you are in very hard or rocky soils. Our recommendation is to try one if you are having problems getting the posts in straight and plumb. We love the flexible nature of PasturePro posts, however this flexible nature also means that when you hit rocks, the posts will want to flex and turn off the rock, thus giving you a post that isn’t plumb.
Now, for a cattleman that is putting in a single wire cross fence that may not be important — they may just want a post to do its job, if it leans or flexes a little, so what. Personally, I am somewhat of a “nut” about sighting down my fence and seeing all the posts in line. So, I like using the pilot driver. If you pilot a plumb straight hole, your post will stand true.
Once the wire is attached and tensioned, it will help align the few that may be a fuzz out of line. The pilot driver is somewhat heavy to lug around, but is sure an improvement over the alternatives in rocky hard soils. Additional note: this pilot driver is not just for PasturePro posts, we have used it on various other kinds of posts as well – with favorable results.
We feel that 12″ of ground penetration is enough for a 48″ post for single wire cross fences. As post height increases and the number of wires that will be attached to the post increases, so should the ground penetration for the post. On a 72″ post, with 5 or more strands of hi-tensile wire attached, then 18″ of ground penetration would be more acceptable.
We sell the PasturePro post into many different geographic locations and get feedback from our customers regarding how far the post should be driven into the ground. That feedback varies from different locations, as it should.
If you are located in sandy western soil, such as the Sand Hills of Western Nebraska – and need more stability, then go with your personal feelings – you probably know your soil better than we do!
So what we are saying here is this: If we say that 12″ of ground penetration on a 48″ post works well here in the Ozarks and you know personally that a 54″ or 60″ would be better for your soil types, then go with your feeling. What probably works the best in this industry is to take the basic recommendations + input from your own personal experiences and knowledge, and adapt it to your own location.
