"Pivot Post" Allows Rotational Grazing Under Center Pivot
Livestock producers in dryland areas who want to practice rotational grazing will like this new Pivot Post that lets center pivot towers roll right over electric fence. It allows you to divide an irrigated circle into as many grazing cells as you want.
The Pivot Post consists of a fiberglass post attached to a spring-loaded cast aluminum base that's anchored to the ground by a short length of steel post. The electric wire attaches to the fiberglass post with cotter keys. A conventional wooden post is used at the center of the pivot span, and a corner post is set outside the circle.
The fiberglass post is placed 5 ft. from the outside of the wheel track. As the pivot tower wheel presses on the fence wire, the wire pulls the post down flat on the ground. Once both pivot wheels have rolled over the wires, the post - and the fence - springs back into position.
A wire diverter attaches to the base of each tower with four U-bolts. It pushes the wire down to keep it from catching on anything.
A spring and ratchet assembly at the end of each wire allows you to adjust wire tension. Support posts are installed halfway between each of the towers. As the fence is tipped over by the pivot wheels, the wires slide inside insulators on the posts.
According to the company, livestock won't cross the fence as the sprinkler is going over it, because they fear the wire and are afraid to touch or cross it even as the center pivot crosses over it. The company recommends the use of high tensile 12 1/2-gauge smooth wire. Two smooth fence wires are recommended to ensure that the pivot wheel catches the wire.
The fence should be offset about 15 ft. from the center of the pivot so that all the towers don't cross the fence wires at the same time. This reduces stress on the wire and springs.
A variety of paddock setups are possible.
