Abstract: An agricultural machine includes a chassis, a liquid tank, a spray boom assembly, and a conduit. A nozzle body including a plurality of nozzles is located on a bottom side of the boom. A transponder tag is placed on each nozzle of the nozzle body and includes specific information regarding characteristics of the respective nozzle. A reader assembly emits electromagnetic waves through an antenna to receive information from a particular transponder tag. The transponder tag receives the electromagnetic waves and generates a signal that includes the specific information. Each nozzle is movable into an active position by rotation of a nozzle turret. The reader assembly is located such that a transponder tag of a nozzle enters communication range when the nozzle is placed in the active position. A controller receives the specific information and identifies characteristics of the nozzle in the active position.

Abstract: An agricultural machine includes a chassis, a center frame mounted for vertical movement, and laterally extendable right and left foldable booms. A sprayer boom controller includes positioning data. A first identification system transmits a predefined frequency radio signal at a first point in time. A second identification system on the right boom and a third identification system on the left boom receive the radio signal. An identification system calculates actual distances between the first and second identification systems and the first and third identification systems based on the wavelength of the radio signal and the differences of the first and second points in time and the first and third points in time. Information regarding the actual distances is transmitted to the sprayer boom controller which compares the calculated distances with the predetermined positioning data and stops folding and/or unfolding in response to determining they exceed or underrun a tolerance value.

Abstract: A trailed agricultural implement is disclosed. The trailed agricultural implement includes a hydraulically-driven pump for moving a fluid at an actual fluid rate. An electro-hydraulic valve is configured to regulate an implement hydraulic pressure to the hydraulically-driven pump. The hydraulically-driven pump regulates the actual fluid rate. The electro-hydraulic valve is configured to receive a vehicle hydraulic pressure. The electro-hydraulic valve communicates with a vehicle load sense system. The load sense system senses the implement hydraulic pressure and communicates with a vehicle hydraulic pump. The vehicle hydraulic pump adjusts the vehicle hydraulic pressure to correspond to the implement hydraulic pressure.

Abstract: A spraying apparatus (19) for an agricultural field sprayer (10) having at least one spray line (32) disposed on the spraying boom (20), and a plurality of discharge openings (36) disposed along the spray line (32) connected by a part (38) to an inlet opening (66, 76) of a spray nozzle body (40, 70). Fluid flow from the inlet opening (44) to the nozzle body inlet opening (66, 76) is along a straight line fluid path. The connecting part (38) is configured as a valve housing. A ball (54) is responsive to a magnetic field generated by a coil (52,68) for movement away from a closed position located generally on the straight line fluid path to an open position offset from the path.
