Abstract: A system for controlling the operation of an agricultural sprayer includes a boom assembly having a boom arm 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. Additionally, a computing system is configured to determine the position of a portion of the boom arm relative to the frame in a plane defined by a longitudinal direction and a vertical direction based on the data generated by the sensor. The longitudinal direction is parallel to the travel direction and perpendicular to the lateral direction, while the vertical direction is perpendicular to the lateral direction and the travel direction. Additionally, the computing system is configured to control the operation of the nozzle assembly based on the determined position of the portion of the boom arm relative to the frame.

Abstract: 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.

Abstract: A boom center section for an agricultural machine includes a bulkhead having a first end and a second end, at least one bulkhead opening located adjacent at least one of the first and the second ends of the bulkhead, and at least one connection assembly disposed within the at least one bulkhead opening.

Abstract: An alternative traction control system, in addition to a primary traction control system, is associated with an agricultural machine in which a user selectable input can allow wheels of an the agricultural machine to spin freely, such as for clearing debris from tires, until a predetermined deactivate condition occurs. Such a deactivate condition could comprise, for example, reaching a maximum rotation speed and/or temperature threshold with respect to a wheel. To minimize the risk of damage to propulsion components which may be caused by excessive rotation speeds and/or temperatures, upon reaching such a threshold, operation can return from the alternative traction control system to the primary traction control system. Such a system can therefore allow an “on the fly” change that would permit an operator to selectively spin the tires without damaging mechanical aspects of the agricultural machine.

The top plate has a first thickness at a first location of the chassis frame to provide additional strength to the chassis frame at the first location. The top plate has a second thickness at a second location of the chassis frame to provide additional strength to the chassis frame at the second location.

Abstract: A chassis frame including a top plate, a bottom plate spaced apart from the top plate, a plurality of side plates extending from the top plate to the bottom plate, a plurality of mounting tabs extending from at least one of the top plate and the bottom plate and being integrally formed therewith, and a plurality of mounting brackets permanently coupled to at least one of the top plate and the plurality of side plates.

Abstract: A suspension control system dynamically adjusts pistons located proximal to wheels of an agricultural machine to substantially equalize distribution of weight of the machine at each wheel and/or provide a substantially constant desired orientation of the machine above a ground surface thereby protecting laterally extending sprayer booms from contacting the ground. Articulation, pitch, roll and/or machine height can be determined from piston measurements on the machine to apply such height corrections. For sprayers, this allows controlling clearance and suspension height to maintain the boom parallel to the ground to prevent damage.

Additionally, the split deck rail may include a ladder that an operator can walk up to get to the deck sections.

Abstract: The present invention provides an agricultural product delivery system in which a support structure or skid well is configured to rigidly support a primary product storage tank that is manufactured from a non-metallic material such as polyethylene or plastic. The product storage tank can have a capacity of at least 500 gallons, and preferably 1000 gallons, and the support structure can include multiple support ribs spaced along sides of the tank for providing rigid support for the tank and preventing deformation when filled with liquid. In addition, the product storage tank can include one or more contours or cavities for accommodating smaller chemical injection tanks positioned therein. Such chemical injection tanks can also be rigidly supported by the support structure. A spray system can mix liquid from the product storage tank and chemical from a chemical injection tank for spraying a field.

Abstract: A high clearance sprayer with a four-wheel steering system includes a steering input, a steering control system, a front steering system, and a rear steering system. The front and rear steering systems are mirrored images of one another, which simplifies and improves the accuracy of the four-wheel steering control methodology. In doing so, the control system may calculate a single value that is used for controlling the front steering system, and an inverse of the single value that is used for controlling the rear steering system. Both of the front steering system and the rear steering system include wheels, steering actuator systems, swingarms, and wheel supports, which all of position of the wheels relative to the sprayer to be rotated. The steering control system may allow for various steering maneuvers to occur, including a turn-steering maneuver and a crab-steering maneuver.

Abstract: A self-propelled agricultural sprayer can be configured with a spray boom, adjustable width wheels and rear wheel spray nozzles arranged over rear wheels of the adjustable width wheels, so that the rear wheel nozzles ensure proper coverage of an agricultural field behind the rear wheels according to location. A control system can determine front wheel nozzles disposed on the spray boom that are counterpart spray nozzles to the rear wheel nozzles based on a width of the wheels, and implement activation/deactivation states of the rear wheel nozzles based on the counterpart front spray nozzles. The activation/deactivation states of the spray nozzles can be determined by geographic location of the machine using a UPS location. The rear wheel nozzles can be arranged with respect to fenders of the rear wheels, so that the rear wheel nozzles move laterally with the rear wheels.

Abstract: A protected tread widening system for a self-propelled high clearance sprayer. The system includes a frame with side rails and a first cross member and a second cross member extending between the opposite side rails, with the cross members being substantially hollow. Each of the cross members form slider receivers. The system also includes axle slider assemblies that are telescopically inserted into the slider receivers. Additionally, actuators are mounted within the cross members. These actuators are secured to the frame and to the axle slider assemblies to allow for telescopic movement of the axle slider assemblies into and out of the cross members. The actuators run substantially through a central axis of the first cross member and a central axis of the second cross member. This minimizes the bending moment of each actuator. Additionally, this system isolates the actuators from materials outside of the cross members.
