An agricultural trailed implement includes a chassis with tongue for hitching to a tractor. A housing is integrated into a loadbearing section of the tongue. A pump or generator is mounted inside the housing and is driven by a PTO shaft connected to an attached tractor. The pump housing may define a sump which provides a fluid reservoir to supply the pump in a hydraulic circuit.

An agricultural sprayer having a liquid supply conduit for directing selectively controllable pressurized liquid to a plurality of spray nozzle assemblies. Each nozzle assembly includes a nozzle body having a respective orifice member having an inwardly tapered conical section communicating with a smaller diameter discharge orifice. Each respective orifice member is made of a resilient and pressure responsive deformable material such that upon an increase in the pressure of the liquid supply said liquid flow passage and discharge orifice thereof can be altered to increase the rate through said orifice member and nozzle body by at least 75 percent and upon interruption of the supply of pressurized liquid to the orifice member the orifice member liquid flow passage and discharge orifice return to their original shape.

A fluid sprayer includes a tank containing fluid therein and a nozzle assembly in communication with the tank to receive fluid therefrom and to atomize the fluid. The fluid sprayer also includes a blower assembly positioned upstream of the nozzle assembly for dispersing the atomized fluid from the nozzle assembly into the surroundings of the fluid sprayer and a discharge chute positioned downstream of the blower assembly into which the atomized fluid from the nozzle assembly is sprayed before being discharged upward and into the surroundings of the fluid sprayer.

A system and method for predicting a future wind direction and speed and, based thereon, determining a future wind-driven drift and providing the information to an operator or automatically acting to adapt application parameters to better control the wind-driven drift of a fluid during application of the fluid to land or crops by an agricultural machine. A processor receives machine and meteorological data, uses a model to predict the future wind direction and speed, and accesses a drift distance database to determine and visually depict the future wind-driven drift of the fluid. A sensitive area database stores information about sensitive areas bordering the target area, which may also be displayed, to facilitate controlling the wind-driven drift with regard to the sensitive areas. The mathematical model may be a kernel filter, an autoregressive model, an autoregressive integrated moving average model, or a hybrid model which incorporates features of different models.

A self-propelled agricultural application machine includes a chassis which carries a storage tank for the material to be applied. The chassis has a central longitudinal beam from which at least a pair of wheels is suspended. A transversely-extending boom assembly is suspended from the longitudinal beam. An engine is located to one side of the longitudinal beam and has an output drive shaft connected through the longitudinal beam to hydraulic pumps. The narrow chassis allows steerable wheels to be positioned at tolerable track widths while permitting a large steering angle and thus small turning radii.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluid to plants in rows in a field includes at least one applicator arm that is actuated by an actuator to move the applicator arm from a position in the row between plants to a position adjacent to the plant.

Systems and methods of the present disclosure include the use of a tracer in agricultural spray solutions, and preferably a metal tracer, to determine if off-target drift of an active ingredient (AI) is based on drift caused during application or volatility of Al after application.

A system for controlling an operation of an agricultural sprayer includes a boom assembly having a frame, a boom arm coupled to the frame, and a nozzle assembly supported on the boom arm. Furthermore, the system includes a sensor configured to generate data indicative of a position of the boom arm relative to the frame in a plane defined by a lateral direction and a vertical direction, which are perpendicular to a travel direction of the sprayer. Additionally, a computing system is configured to determine the position of the nozzle assembly relative to the frame in the plane defined by the lateral direction and the vertical direction based on the data generated by the sensor. Additionally, the computing system is configured to control an operation of the nozzle assembly based on the determined position of the nozzle assembly relative to the frame.

An air assist spray assembly for an aerial vehicle as shown and described. The air assist spray assembly may include a boom structure having a plurality of spray nozzles configured to dispense fine and course spray droplet sizes. The spray nozzle may be an electrostatic type of nozzle. The boom structure may include an air curtain system that includes an elongated air passageway with a plurality of air nozzles. The air curtain system may include a front air curtain and/or a rear air curtain to assist with directing the spray of electrostatically charged fine and coarse droplets from the spray nozzles towards vegetation.

An agricultural sprayer assembly includes a wheeled carriage, a chassis, and a spray delivery system. The wheeled carriage has a number of adjustable support legs (e.g., four), each formed of hydraulically coupled and actuated upper and lower leg sections or members. The chassis is supported on the wheeled carriage, at an adjustable clearance height defined by the operational height of the support legs. The spray delivery system includes a spray boom coupled to a boom support, and an actuator coupled to the boom support and the chassis. The actuator is configured to adjust the height of the spray boom with respect to the clearance height of the chassis.
