Transitions, dips, and ridges are good places to use a wood post as a boss post. Remember, the PasturePro post a line post and it serves that purpose wonderfully. Just as in any type of fence – at bends, transtitions, severe ridges and dips, you will need a non-flexible post. We recommend using a wood post in places where you will be having pulls in either vertical or horizontal directions.
In going over hills or severe ridges, it may be prudent to just plant a good wood post at the ridge-top. I’ve noticed that when I do not get that ridge post exactly in line, it will bend horizontally with the wire pressure when you tension up the wire. So, as a suggestion, I would recommend using a wood post in this situation when you are building fence over lots of hills.
