Systems and methods are provided for determining a leaf-to-stem ratio of a crop automatically from an image of the crop. An agricultural vehicle may include a crop analysis system having a computing device and an imaging device for capturing an image of a crop. The computing device analyzes images acquired by the imaging determine to determine a leaf-to-stem ratio of the crop.

A detection system that can identify fluid connections between a plurality of control valves of, including secured to, an agricultural vehicle and an implement of an agricultural machine. Information captured by a sensor(s) can provide information that identifies one or more identifiers, each identifier being coupled to a different conduit that is used in the exchange of hydraulic fluid between the agricultural vehicle and the implement. The identifier can also correspond to recorded information regarding the particular subsystem or operation of the implement to which the conduit associated with the identified identifier is fluidly coupled. Additionally, information captured by the sensor can be used to detect the particular control valve to which the conduit associated with the identified identifier is coupled. Such information can be used in the identification, or assignment, of the particular control valve that is fluidly coupled to a particular subsystem or operation of the implement.

A baler system includes a baler controller includes a processor operable to execute a bale ejection algorithm to receive a command input to initiate a last bale ejection sequence. Upon receiving the command input, the baler controller automatically engages a knotter system to wrap and bind crop material currently disposed within a baling chamber to form a final bale. Upon forming the final bale, the baler controller automatically determines if a discharge location disposed proximate a discharge end of the baling chamber is clear of obstructions. Upon determining that the discharge end of the baling chamber is clear of obstructions, the baler controller automatically engages a bale ejection system to eject the final bale from the baling chamber and onto the discharge location.

An agricultural machine includes a main frame, a rockshaft pivotably coupled to the main frame, a lift actuator couple between the rock shaft and the main frame, a lift arm pivotably coupled to the main frame below the rockshaft, a lift strap coupled between the rockshaft and the lift arm, and a lift actuator coupled between the main frame and the lift strap to pull the lift arm upwards. The agricultural machine includes header, which is supported by the lift arm and the float actuator above the ground at a desired harvesting height. During harvesting, the lift arm may encounter uneven ground, causing the header to move away from the desired harvesting height. By measuring float actuator pressure or header position and by changing the pressure in the float actuator or lift actuator in response, the header can be rapidly returned to the desired harvesting height.

A cruise control system and method for a work vehicle with vehicle interlocks, and a controller. Each vehicle interlock monitors a vehicle system status. When at least one of the vehicle interlocks is triggered, the controller notifies the operator of the triggered interlock and deactivates cruise control. An activation mechanism can activate cruise control. When the activation mechanism is activated and none of the vehicle interlocks is triggered, the controller activates cruise control and maintains current vehicle ground speed at a vehicle cruise speed. When the activation mechanism is deactivated, the controller deactivates cruise control. The cruise speed can be set to the current vehicle ground speed, or can be set by a speed selection mechanism, or can resume at a previously selected cruise speed, or can be set by another method.

A self-propelled agricultural harvester machine comprising a machine frame, a plurality of ground engaging units for supporting the machine frame from a ground surface, a header assembly for harvesting stalked crops, the header assembly being supported from the machine frame so that the header assembly can be raised, lowered, and tilted relative to the machine frame, at least a first sensor configured to sense at least an orientation of the stalked crops in a path of the agricultural harvester machine, the first sensor configured to output a crop orientation signal, and a controller configured to receive the crop orientation signal from the first sensor and to regulate a header assembly angle relative to the machine frame at least in part in response to the crop orientation signal.

A power management system and method for a work machine that receives real time data, computes current power requirements based on the real time data, computes an optimized engine speed based on the current power requirements and a desired reserve power, and informs an operator of the optimized engine speed. The system can predict upcoming power requirements based on real time and predictive machine data, and compute the optimized engine speed based on the current and upcoming power requirements and the desired reserve power. The system can also receive predictive data, and predict the upcoming power requirements based on the predictive and real time data. Predictive data can include topographical data and/or historical power-consumption data. The system can include an automatic mode where the system automatically adjusts engine speed to the optimized engine speed. The system can maintain a constant machine ground speed as it automatically adjusts engine speed.

A round baler implement includes a forming belt having a first longitudinal end and a second longitudinal end coupled together by a retaining pin to secure the forming belt in an endless loop. An image sensor is positioned and operable to capture an image of the retaining pin. A baler controller receives a current image of the retaining pin from the image sensor and determines a wear condition of the retaining pin therefrom. The baler controller may then communicate a notification signal to a communicator providing the wear condition of the retaining pin, thereby notifying user of the condition of the retaining pin so that the user may decide to replace the retaining pin when necessary.

A method of defining an end travel limit of an electric actuator includes sensing an electric current of the electric actuator while moving the electric actuator from a first position to a second position. A maximum travel current of the electric current sensed during movement of the electric actuator between the first position to the second position is increased by a factor to define a maximum calibration current. The electric current is then sensed while moving from the second position toward an end travel position of the electric actuator. Movement of the electric actuator is stopped at a fault position when the electric current equals the maximum calibration current. The end travel limit of the electric actuator is then defined as a function of the fault position.

End travel limit calibration of an electric actuator

A work implement includes a support controller disposed in communication with a hydraulic lift cylinder. The support controller initiates a control activation signal for commanding movement of the hydraulic lift cylinder to move the head support from an initial start position to a commanded support position. The support controller determines a stop signal position based on the current rate of movement of the head support toward the commanded support position. The stop signal position may further be based on a current fluid pressure of an associated float system. The support controller ceases or stops the control activation signal when the head support reaches the stop signal position, whereby the head support decelerates over a distance after cessation of the control activation signal such that the head support substantially stops movement at the commanded support position.

A baler implement includes a bale formation system operable to form crop material into a bale and eject the bale into an unloading zone. An object detection sensor is positioned to detect data related to the unloading zone. A baler controller is operable to determine if an object is present in the unloading zone or if an object is not present in the unloading zone based on a data signal from the object detection sensor. When an object is not present in the unloading zone, the controller may initiate the bale ejection sequence to eject the bale. When an object is present in the unloading zone, the controller may prevent initiation of the bale ejection sequence to prevent ejection of the bale onto the object.
