Spring-loaded post lets sprinkler drive over electric wire.
A new flexible fence post from Pivotal Fencing Systems takes the time and hassle out of using a center pivot irrigation system across electric fencing.
The bendable, electric post is attached to a heavy spring. When the wheel of the irrigation system rolls across electric fence wire, the post bends over and then springs back up. The post is designed for cattle-grazing systems where pasture is grown under a center pivot irrigation system. The irrigated circle may be fenced into grazing cells because the sprinkler moves over the wires without any help from the producer.
Construction. The post is a 7/8-in. solid fiberglass rod that is 30 in. long and predrilled for wire attachment. The post is mounted on a cast aluminum base and a removable spring. To help the sprinkler drive over the electric wire, a Pivotal Fencing Systems wire diverter must be mounted to the sprinker tower basebeam. The diverter keeps the wire from catching on the sprinkler’s drive line, boxes, etc.
The company recommends using high-tensile, 12 1/2- gauge smooth wire that is free of kinks and splices. Barbed wire will not slide through the fasteners. The wire does not stretch and break because a spring-and-ratchet assembly installed at the end of each wire provides proper tension when the sprinkler pulls it to the ground.
Time-saver. "The pivotal fence saves a cattle producer a lot of time and labor," reports Adam Gates with Pivotal Fencing Systems. "They don’t need to build special gates, take down fencing or be at the fence when the sprinkler will go over it."
Cattle do not cross the fence during the brief time it is on the ground when the sprinkler crosses it because they fear touching the electric wire, Gates adds.
