Center pivot machines have been used in irrigation for decades. Center pivots, one of several types of mechanized irrigation machines, can lead to increased yields and less water wasted compared to other irrigation practices such as flood irrigation.
Center pivot irrigation is a form of overhead sprinkler irrigation consisting of several segments of pipe (usually galvanized steel or aluminum) with sprinklers positioned along their length, joined together and supported by trusses, and mounted on wheeled towers.The machine moves in a circular pattern and is fed with water from the pivot point at the center of the circle.
Most center pivot systems now have drops hanging from a u-shaped pipe called a gooseneck attached at the top of the pipe[clarification needed] with sprinkler heads that are positioned a few feet (at most) above the crop, thus limiting evaporative losses and wind drift. There are many different nozzle configurations available including static plate, moving plate and part circle. Pressure regulators are typically installed upstream of each nozzle to ensure each is operating at the correct design pressure.
