How does the Pivot Post work?
The Pivotal Fencing System™ is all about flexibility in both literal and figurative terms. The key to the system is the Pivotal Fence Post™, a fiberglass post fitted and fixed to a spring-loaded cast aluminum base. By anchoring the Pivotal Fence Post to the ground with a steel t-post and attaching electric wire to the post with cotter-keys, an electric fence can easily be constructed in any type of terrain-a fence that will bend but not break.

Consider pasture grown with center pivot irrigation, for example. With the Pivotal Fencing System, an irrigated circle can be cross-fenced into as many grazing cell as a producer wants. With the use of the system's Wire Diverters attached to the sprinkler, it moves around the circle in either direction, approaches the fence, bends it down, rolls over it and the fence springs back into place.

Likewise, the inherent flexibility of the Pivotal Fencing System means that native pasture and dry land used for forage can be easily cross fenced with electric wire without the threat of livestock or wildlife knocking the fence down.

How many Pivot Posts do I need?


Only ONE Pivotal Post™ per sprinkler tower is needed! A conventional post is used in the center of the span.

What is the Pivotal Post made of?


The Pivotal Post is made up of three major components. The base is cast of an aluminum alloy for longevity. The return mechanism consists of a spring made from oil tempered rod. The post consists of a predrilled full seven eighths inch fiberglass rod.

Does the sprinkler tire run over the Pivotal Post?


No, the Pivotal Post is placed five feet on the outside of the wheel track. The sprinkler tire presses on the fence wire which in turn lays the post over.

Does the system work if the wheel tracks are deep?


Yes, but in order for the fencing system to work the tire must catch the wire. For exceptionally deep wheel tracks it may be necessary to fasten the bottom wire to the lowest predrilled hole in the fiberglass rod.

What kind of wire works best?


We strongly recommend the use of high tensile 12 1/2 gauge smooth wire. Excellent wire, free of splices and kinks, functions trouble free. Barbed wire will not slide through the cotter key fateners.

Will this system work in rough terrain?


Yes, the Pivotal Fencing System™ shines in adverse conditions. One producer who has tried virtually everything recently purchased our system and said their problems are finally solved.

What keeps the wire from catching on the centerdrive gearbox?


An important part of the system is the wire diverter which is mounted on poly blocks for insulating purposes and is attached to the sprinkler tower basebeam with four U-bolts. The diverter hangs below all obstructions on the tower and allows the wire to slide along it.

What keeps the wire from stretching and breaking when the sprinkler crosses it?


Our spring and ratchet assemblies are installed at the end of each wire in order to provide the proper tenstion of optimum fence operation.

Does the fence ground out when the sprinkler crosses over it?


Modern fences are far more resistant to grounding and often a shocking sensation is still felt on the other side of a direct ground.

Do cattle cross the fence as the sprinkler is crossing it?


No, an electric fence is a mental barrier rather than a physical one. The cattle fear the wire and are extermely hesitant to touch or cross the wire when it is being crossed by the sprinkler.
