Where grazing by cattle is anticipated, sprinklers should be kept above their reach, to avoid interference.
Cattle normally avoid an operating pivot (except perhaps in hot weather), and pugging is not normally an issue so under most conditions cattle can be left in the paddock during irrigation.
Fencing and access needs to be considered. Fencing can be radial (segments), or circular (‘donuts’), with narrower paddocks towards the outside if equal-area grazing units are required. Fencing and laneways existing prior to the pivot being installed may be utilised, but pasture and grazing management may require some compromises.
“Gates” just wide enough for the towers to pass through (1 to 2 m) can be used where the towers have to cross a fence. Flexible rods attached to an electric fence will prevent cattle movement but allow the towers to pass.
Skids fitted to towers can enable towers to pass over long (flexible) fence spans. However, the fence can become wrapped around the wheel hubs if this isn’t set up well.
Circular fencing under the pivot - note the paddocks are narrower towards the outside of the circle.
