摘要： An irrigation system includes a central pivot and a series of mobile towers connected to the central pivot and to one another by support structure. Each mobile tower has wheels and a motor for driving at least one of the wheels. A control system operates the motors to maintain alignment of the mobile towers and the central pivot while preventing power usage of the system from exceeding a maximum power threshold. The control system determines in which sequence to operate the motors to maintain alignment of the mobile towers while operating no more than a selected number of the motors simultaneously.

摘要： A wheel assembly including a rigid wheel and a flexible tire. The rigid wheel includes a radially outer rim wall, a plurality of mounting elements, and a plurality of inflatable spacers between the mounting elements. The flexible tire may be mounted on the mounting elements of the rigid wheel such that portions of the flexible tire between the mounting elements are separated from the outer rim wall by spaces between the mounting elements and are configured to flex inwardly when subject to ground engaging pressure. The inflatable spacers limit the amount of inward flex of the inwardly flexible portions of the flexible tire.

摘要： A lateral irrigation system comprising a plurality of towers and a plurality of lateral structures extending between and connected to the towers. The support structures may comprise a first support structure, a second support structure pivotable relative to the first support structure, and a third support structure pivotable relative to the second support structure. The irrigation system may also comprise a fluid delivery system having conduits attached to or extending through the support structures and configured to output water from orifices formed therein. The irrigation system may further comprise joints at which the second and third support structures may pivot. The second and third support structures may be configured to pivot into a substantially zig-zag or “Z”-shaped configuration relative to the first support structure.

摘要： A wheel assembly includes a collapsible wheel and an airless flexible tire mounted on the wheel. The wheel includes a central portion and a plurality of circumferentially spaced mounting elements attached to the central portion. Each of the mounting elements is movable between a retracted position and an extended position, and may be pivotally attached to the central portion of the wheel and configured to pivot between the retracted position and the extended position. The tire may be positioned on the wheel when one or more of the mounting elements is in the retracted position, and the one or more mounting elements are moved to the extended position wherein the mounting elements engage and support the tire.

摘要： A planting and irrigation apparatus and method for planting seeds in and irrigating a field. The apparatus may comprise a plurality of spray nozzles configured with a pressure setting sufficient for forming a plurality of holes into soil of the field and a seed dispenser configured for dispensing one or more seeds into one or more of the holes. Once the seeds are dispensed throughout the field, the apparatus may irrigate the field, thereby washing soil displaced when the holes were formed back into the holes, thereby covering the seeds.
