The present invention relates to a method of selectively spraying an area of a cultivated field (10) with an agriculture spraying vehicle. The vehicle comprises a spraying equipment (200) having at least one imaging system (210), and at least one trailing spray bar (300) comprising a plurality of electromechanical nozzles (310) spaced apart from each other by a constant pitch distance. The plurality of electromechanical nozzles (310) includes a corresponding plurality of nozzles (314) and of electromechanical valves (312). The agriculture spraying equipment (200) further comprises a control unit (220) including a processing unit to control the electromechanical valve (312) of each electromechanical nozzle (310). The method comprises: i) acquiring, by the at least one imaging system (210), an image of an area of the cultivated field (10) and differentiating on the image, by the processing unit, a plant (14) to be sprayed from a plant (12) which shall not be sprayed; ii) determining at least one nozzle (350) which is about to be substantially vertically positioned above a plant (14) to be sprayed; iii) computing a spraying pattern on the area based on the divergence angle of said at least one nozzle (350) and the vertical distance between said nozzle (350) and said area to be selectively sprayed, said spraying pattern covering the plant (14) to be sprayed and possibly touching a plant (12) which shall not be sprayed; iv) computing a distance called the jet shift distance (354) to laterally shift the spraying pattern such that the shifted pattern covers the plant (14) to be sprayed without covering the plant (12) which shall not be sprayed, and express said jet shift distance (354) as a multiple of said nozzle-to-nozzle pitch, and v) laterally shifting said spraying pattern by shifting the at least one nozzle (350) vertically positioned above a plant to be sprayed (14) by said jet shift distance (354) so that the spraying pattern from the at least one newly selected nozzle (352) does not spray the plant that shall not be sprayed (12).

A boom for mounting to an agricultural sprayer comprises an elongate frame supporting a plurality of liquid application devices, liquid delivery means connected to the application devices, and an elongate tray attached to, and extending along, the boom. The tray is movable between a first position in which the tray extends substantially horizontally beneath one or more of the application devices to prevent material from leaking onto the ground below, and a second position in which the tray is located clear of delivery paths of the liquid application devices.

Methods for providing compositions to corn fields prior to harvesting are provided herein. These methods provide an extended time period for the use of lower height or standard height farm equipment in-season in corn fields, while reducing the risk of damage to the corn plants. These methods also allow for late season access with lower height or standard height farm equipment, while reducing the risk of damage to the corn plants.

A sprayer system is provided for a work machine that includes a boom, a fluid source, and an air source. The sprayer system includes a spray device configured to selectively apply a fluid from the fluid source to an agricultural crop. A retractable arm includes a first arm segment, a second arm segment, a first hinge joint positioned such that the first arm segment is selectively foldable relative to the boom, and a second hinge joint positioned such that the second arm segment is selectively foldable relative to the first arm segment. An actuation assembly coupled to the retractable arm selectively folds and unfolds the first arm segment relative to the boom at the first hinge joint and the second arm segment relative to the first arm segment at the second hinge joint based on air pressure from the air source.

In one aspect, a control system is provided which determines fluid flow in a suspension system for an agricultural machine by determining total fluid in a closed loop piston system. Fluid is determined using position sensors and a pressure transducers and application of the ideal gas with respect to each accumulator. A closed loop control system can then target an amount of fluid for optimum suspension control.

In one aspect, a suspension control system is provided for dynamically adjusting pistons located proximal to wheels of an agricultural machine to account for tire deflection or squat with varying loads. Articulation, pitch, roll and/or machine height can be determined from pressure measurements on the machine to apply such tire height corrections. For sprayers, this allows controlling clearance and suspension height to maintain the boom parallel to the ground to prevent damage.

A front-boom sprayer is provided that includes a boom center section and lift arm arrangement that provides a field of view below the boom when the boom is in a raised state that is substantially free of view obstructions from torque tube or other crosswise-extending components. The lift arm arrangement may provide different link tube geometries so that the respective left and right pairs of upper and lower lift arms align with each other in the line of sight of the in-cab operator.

A localized product injection system includes a composite boom tube having a carrier fluid passage within a tube body, and at least one injection product passage within the tube body isolated from the carrier fluid passage. A plurality of port stations are provided at locations along the tube body. Each of the port stations includes a carrier fluid outlet port and at least one injection product outlet port. A localized injection interface is coupled at a port station. The injection interface includes a carrier fluid input coupled with the carrier fluid outlet port, and at least one injection product input coupled with the at least one injection product outlet port. The injection interface includes at least one throttling element in communication with the at least one injection product input, a mixing chamber, and an injection port configured for localized coupling and injection to a product dispenser.

An agricultural sprayer arrangement includes a chassis, at least one ground engaging traction member carried by the chassis, a liquid tank carried by the chassis, a boom carried by the chassis, a fluid conduit associated with the boom that is fluidly connected to the liquid tank, a spray nozzle that is fluidly connected to the fluid conduit and includes a nozzle body, a differential pressure sensor with a first pressure sensor in the fluid conduit associated with the spray nozzle and a second pressure sensor in the nozzle body, and an electrical processing circuit coupled to the differential pressure sensor. The differential pressure sensor is configured to output a pressure difference signal and the electrical processing circuit is configured to report a blocked nozzle when the pressure difference signal is less than a predetermined threshold value.

A vehicle platform comprises a central body that can support one or more implement configurations, such as sprayer booms, or planting row units. A plurality of adjustable legs extends downward from the central body. An arm assembly has a first end and a second end opposite the first end. The first end is pivotably coupled the central body and the second end coupled to a support beam. A plurality of nozzle assemblies is supported from the support beam. An arm actuator is arranged to control a transverse position of the support beam and the nozzle assemblies with respect to a reference point on the central body, such that each nozzle assembly may be aligned with a row of seeds or plants.
