Control Speed and Direction

Precision Point Control III (PPC III) from T-L Irrigation is the newest addition to the company’s midlevel series of pivot control systems. The PPC III enhances real-time operational control and provides more information than previous systems. The technology offers five variable application areas within the pivot’s circle in both forward and reverse operation. By using a GPS or encoder position sensor, a farmer can make adjustments by degree within the circle and determine the irrigation pivot’s speed by entering the desired water application rate. When combined with T-L’s hydrostatic design, the PPC III assures uniform water application, improved crop production and
effective system management. The PPC III features a user-friendly control panel that shows speed versus actual speed, speed sensor operation, the system’s current run-time and relevant GPS data, such as latitude and longitude.

Get in Gear

LindsayATGearboxNew from Lindsay Corporation, the AT gearbox, which is part of the Zimmatic product line, showcases a new design, replacing the PowerDrive gearbox. With durability and efficiency in mind, features include stouter housing for less wear, forged steel gears, cartridge seals and large bearings on both sides of the input shaft. The AT gearbox includes a universal mounting pattern, externally gusseted bell housing and a shorter output shaft that helps eliminate high overhang load and extend bearing life. The easy-fill design allows for routine maintenance without opening the expansion chamber. Contact: Lindsay Corporation, 2222 North 111th St., Omaha, NE 68164; (866) 404-5049;

30° Angle Can Lower Irrigation Cost

NE Bender30 (2) ValleyWould you like to be able to stretch your irrigation system over a few additional acres? Valley Irrigation’s Bender30 bends any drive unit at a 30° angle, allowing the system to easily wrap a tree line or feedlot and avoid obstacles in the field to maximize irrigated acres. Not only does the Bender30 require no structural changes to existing spans, it comes with the options of a tower-control box that contains overextension safeties and monitors to ensure that the unit straightens back to its original position. Other features include multiple bends per machine and optional water shutoff valves to stop the span while bending. Bender30 is available for all ball-and-socket pipe except 10", and the kit includes one barricade. Contact: Valmont Irrigation, P.O. Box 358, Valley, NE 68064; (402) 359-2201;

Set Up and Go With Portable Reels

Kifco’s portable irrigation system, Ag-Rain Water-Reels, is designed for use on crop fields, hay ground and pastures. The simple set-up-and-go system can irrigate anywhere from 2.8 acres to 11.6 acres per run and can cover a field more than a quarter-mile long. The irrigation tube retracts using a highly efficient water-powered turbine or, for low-pressure applications, a gas-powered engine. A model can be selected based on chassis size or tube length and diameter, depending on what works for the area(s) you want to irrigate. Tube lengths range from 660' to 1,575', and tube diameters range from 2.3" to 4.5". Ag-Rain Water-Reels, which can be easily maneuvered by a single person, are ideal for irregularly shaped fields where pivots aren’t feasible and corners of fields where a pivot can’t reach. The system offers flexibility to apply water at various depths based on what the crop requires. Contact: Kifco, 700 S. Schrader Ave., Havana, IL 62644; (800) 452-7017;
