An agricultural product application system includes at least one sprayer boom extending between boom proximal and boom distal ends. The sprayer boom includes a plurality of sprayer nozzles distributed along the sprayer boom and agricultural product plumbing interconnected with each of the sprayer nozzles. One or more processors are configured to assign a compensation value to one or more sprayer nozzles, the compensation value based on one or more of boom kinematic characteristics of the sprayer boom or vehicle kinematic characteristics of an agricultural sprayer. The one or more processors monitor a target relative to at least one sprayer nozzle of the one or more sprayer nozzles and the assigned compensation value. The one or more processors initiate spraying of an agricultural product from at least one sprayer nozzle while the target is coextensive with the at least one sprayer nozzle having the compensation value.

A gauge wheel system for an agricultural header includes a gauge wheel arm assembly configured to rotatably support a gauge wheel and pivotally couple to a header frame of the agricultural header. The gauge wheel system also includes a bell crank configured to pivotally couple to the header frame and a damper pivotally coupled to the gauge wheel arm assembly and the bell crank. The damper is configured to urge the gauge wheel arm assembly to pivot downwardly relative to the header frame while the gauge wheel arm assembly is in a ground-engaging position. The gauge wheel system also includes an actuator coupled to the bell crank and configured to couple to the header frame. The actuator is configured to drive the bell crank to rotate to move the gauge wheel arm assembly between a ground-engaging position and a storage position.

The horizontal shaft (120) is supported by a first and a second bearing for rotation around a rotational axis. The processing elements (130) are mounted to the horizontal shaft (120) for rotation therewith and configured to rotate past the opposing element (140) for cooperation therewith. The first vibration sensor (210) is positioned at the first bearing and configured to provide a first vibration signal. The controller (230) is configured to receive the first vibration signal and to determine a condition of the processing elements (130) based on the first vibration signal.

A cleaning system for a cooling unit of an agricultural vehicle. The cleaning system includes a fan configured to deliver air (i) in a forward direction for cooling the cooling unit, and (ii) in a reverse direction for removing debris from the cooling unit. A controller is configured to activate the fan to deliver air in the reverse direction after (i) a pre-determined time interval has elapsed, and (ii) the agricultural vehicle is being operated in a pre-determined condition.

Control system (12) including a blower (42) configured to output an airflow (46) via a blower output flow passage (60), a heating system (40) configured to receive the airflow (46) from the blower (42), a heating system valve (80) positioned between the heating system (40) and the blower (42), a computing system (84) communicatively coupled to the blower (42), the heating system (40), and the heating system valve (80), and configured to receive an input, and when the input is related to a change in state of the blower (42), to delay actuation of the blower (42) for a first time period, to alter a blower (42) state during a second time period, to maintain the heating system valve (80) in the target position during the second time period, and to alter a position of the heating system valve (80) to an operation position after an expiration of the second time period.

An agricultural vehicle includes a threshing system that is configured to output straw material in a straw feed stream at a first location of the vehicle. A cleaning system is configured to output a chaff feed stream at a second location of the vehicle. A residue handling system includes (a) sieve that is positioned to receive the straw feed stream and the chaff feed stream, the sieve including a perforated surface through which weed seeds within the chaff and straw feed streams can pass; (b) an auger or conveyor positioned adjacent the perforated surface for threshing the straw feed stream and the chaff feed stream against the perforated surface to cause the weed seeds to separate from the straw material; and (c) a weed seed mill that is configured to receive the weeds seeds that have fallen through the sieve and devitalize those weeds seeds.

A crop loss monitoring system (300) for an agricultural harvester (100) includes a controller (302) configured to receive a left sensor signal from a left sensor (316) indicative of crop particle impacts on a left side of a row unit (208) and to receive a right sensor signal from a right sensor (318) indicative of crop particle impacts on a right side of the row unit (208). Furthermore, the controller (302) is configured to determine whether the row unit (208) is misaligned to a left side of a row of agricultural crops or to a right side of the row of agricultural crops. The controller (302) is configured to determine crop loss based on feedback from the left sensor (316) alone in response to determining the row unit (208) is misaligned to the left side, and to determine the crop loss based on feedback from the right sensor (318) alone in response to determining the row unit (208) is misaligned to the right side.

An agricultural vehicle includes a threshing system that is configured to output straw material in a straw feed stream at a first location of the vehicle; a cleaning system that is configured to output a chaff feed stream at a second location of the vehicle that is different from the first location; and a residue handling system. The residue handling system includes (i) a chaff receptacle positioned and configured to receive weed seeds from both the straw feed stream and the chaff feed stream, and (ii) a weed seed mill that is configured to receive the weeds seeds from the chaff receptacle and devitalize those weeds seeds.

The chopper assembly comprises a rotatable chopper drum (21), comprising a plurality of knives (31), mounted between two sidewalls (40) and configured to cut larger plant material into smaller particles through the interaction of the knives (31)and a set of counterknives (22). According to the invention, a guide surface (42) is mounted on at least one of the sidewalls (40), preferably on both sidewalls, and in the path of a stream of crop material advancing towards the chopper assembly. The guide surface (42) extends between an upstream edge (53,55;66) lying essentially in the plane of the sidewall and a downstream edge (55,57;67) removed from the sidewall. The guide surface is furthermore inclined relative to the sidewall, so as to guide plant material away from the sidewall and in the direction of the knives (31a) located closest to the sidewall. The guide surface thereby prevents plant material from passing between the knives and the sidewall without being cut.

A system (100) for automatically controlling work vehicle operation includes a remote computing system (114) configured to determine settings for the vehicle (10) and expected outcomes at a plurality of locations within a field/work site. Furthermore, the remote computing system (114) is configured to generate a map identifying the settings and the expected outcomes at each location. Additionally, an onboard computing system (106) is configured to control the operation of the vehicle (10) based on the map as the vehicle (10) traverses the field/work site. Moreover, the onboard computing system (106) is configured to determine actual outcomes at each of location as the vehicle (10) traverses the field/work site. In addition, the onboard computing system (106) is configured to compare the actual outcomes and the expected outcomes at each location and apply one or more offsets to the settings when the actual outcomes differ from the expected outcomes by more than a threshold amount.
