Abstract: By using various feedback data on a sprayer system, such as engine speed, wheel speed, sensed temperatures and/or sensed pressures, an onboard logic controller can be used to fine tune parameters of the driveline system in an automatic calibration process. In one aspect, a controller can drive up engine speed and manipulate electrical current being sent to coils of propel pumps and/or wheel motors as current reaches a point where there is no more change in wheel speed as detected by the system, thereby achieving a. calibration setpoint. Additionally, during the automatic calibration process, the machine as a whole can be monitored with respect to several sensors, such as pressures, temperatures, and the like, so that if any parameter being monitored is out of a predetermined range, the calibration can be stopped and not set.

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.

Abstract: An agricultural vehicle having a chassis and an application boom coupled to the chassis. The agricultural vehicle is configured to deliver agricultural product to an agricultural field. The application boom has a boom arm. The boom arm includes a longitudinal truss member, and a longitudinal chase supported by the longitudinal truss member. The longitudinal chase includes a channel. The agricultural vehicle further includes an application system. The application system has a product tank supported by the chassis and storing a volume of the agricultural product for delivery onto an agricultural field, a plurality of nozzle bodies, a piping system delivering the agricultural product to the plurality of nozzle bodies, and one or more control lines coupled to the plurality of nozzle bodies and for controlling the plurality of nozzle bodies. The one or more control lines are supported by the channel.

Abstract: A spray system for an agricultural machine is configured to include a valving arrangement and multiple liquid product lines coupled to spray nozzle assemblies such that the valving arrangement can connect the product lines to the spray nozzle assemblies in different ways to achieve different modes of operation. Such modes can include providing agricultural liquid product flow through the spray nozzle assemblies at differing rates and/or flushing the product through the spray nozzle assemblies in differing directions. This can be achieved by controlling the valving arrangement to selectively connect any of the lines to pump for supplying product, to tank for returning product, or to block the lines to inhibit the flow of product. In one aspect, the product multiple lines can be of different sizes to enable more modes of operation, such as greater or lesser flow rates while spraying.

Abstract: The present invention is directed to a spray system for an agricultural machine in which multiple spray nozzles for spraying a liquid product can be dynamically arranged in number and location along a preconfigured rail acting as a boom. Each spray nozzle can include an attachment arrangement for conveniently attaching, tightening, loosening and/or detaching the spray nozzle with respect to the rail. In one aspect, the attachment arrangement can comprise a fastener configured to tighten or loosen a clip with respect to a body for engaging the rail. A separate product line for supplying liquid product to the spray nozzles can flexibly include numerous ports, more than there are spray nozzles, with some ports attaching to spray nozzles via branch lines, and other ports being sealed to inhibit flow.

Abstract: By using various feedback data on a sprayer system, such as sensed positions of power actuators for turning wheels, an onboard logic controller can be used to fine tune parameters of the steering system in an automatic calibration process. In one aspect, a controller can send an electrical signal to a coil of a hydraulic pump to fully extend a power actuator for turning a wheel in a first direction, then incrementally adjust the signal until a change in position of the power actuator is determined, thereby obtaining a precise magnitude for commanding a full extension of the power actuator. Similarly, the controller can change the signal to fully retract the power actuator for turning the wheel in a second direction, then incrementally adjust the signal until a change in position of the power actuator is determined, thereby obtaining a precise magnitude for commanding a full retraction of the power actuator.

Abstract: A battery combiner may be used to electrically isolate first and second batteries during conditions in which a first battery required for a mechanical drive system may experience excessive power draw. The second battery may be used to provide a switched and/or continuous power source to a control system and/or other electrical devices for reliable operation, and the combiner may join the first and second batteries together such that both are electrically charged by a single alternator during conditions when it is safe.
