Very insoluble and does absorption does not change with pH as sulfentrazone. The most noticeable difference is the height of the pivot point. The smaller diameter of the supply pipe limits the effective length of the mini-pivots to about 800 feet, which is enough to irrigate about 50 acres. Because of their smaller size, they are lighter than standard pivots and may not be as prone to creating deep wheel tracks. The tower drive motor uses direct current rather than three phase AC typical of standard pivots.
Some manufacturers power the mini-pivot using batteries recharged by a solar panel.
Another form of mini-pivot uses a single tower of standard size and span length with a large overhang and power it with an internal combustion engine mounted on the tower. Mini-pivots use the same size drop tubes and sprinklers as standard pivots. They are commonly used for rectangular pieces of land. Flow meters appear to be equipment that many irrigators don't use, don't repair and constantly overlook when managing their irrigation systems. It is common to visit an irrigation pumping plant and find the flow meter not working.
