  • Patent number: 10561070
    Abstract: Monitoring current draw of an actuator associated with a rotating arm on a round baler during a net wrapping cycle is used to determine the position of the rotating arm and actuator, as well as to determine the net tension. The current draw of the actuator may be correlated with the home and insert positions of the rotating arm during the net wrapping cycle; thus by monitoring the current draw, the rotating arm and actuator position is determined and may be provided to aid an operator. The net tension during the net wrapping cycle is a function of the rotating arm and actuator current. A calculation of net tension is determined and provided to an operator, allowing the operator to verify performance issues related to the net tension.

  • Patent number: 9839181
    Abstract: The disclosure relates to a harvester control system that allows for the operation and control of a bottom floor assembly by an operator of a harvester, such as a round baler. The harvester control system generally comprises at least one rotation sensor configured to measure the rotation angle of the bottom floor assembly during the harvesting process, a controller that receives information from the rotation sensor(s), and an operator interface configured to display warning information to the operator if the bottom floor assembly meets certain rotation and time parameters.

  • Patent number: 8935979
    Abstract: A bale size sensing mechanism for an agricultural round baler having bale chamber partially defined by continuous side-by-side belts disposed between a pair of spaced-apart side walls and trained around a plurality of rolls. Bale size sensing mechanisms disposed in each side wall detects the density of the transverse ends of a bale forming within the chamber and provides the measure to a controller which determines the transverse uniformity of the bale. Each sensing mechanism includes a generally planar element having a wedge-shaped periphery with a vertex, the planar element being pivotally coupled to the baler adjacent to the vertex and a portion of the wedge-shaped periphery projecting into the bale-forming chamber to interact with the bale forming therein. The wedge-shaped periphery minimizes open areas within the bale chamber into which turbulent crop could enter and jam the sensing mechanism.

  • Patent number: 8106529
    Abstract: A farm implement towed or pushed by a vehicle includes at least one electrically actuated device mounted for operation and a high capacitance capacitor connected in circuit with the device and with a source of electricity on the vehicle. Electric power is supplied from the vehicle to the implement at a nominal rate to charge the capacitor and/or operate the device. The capacitor is selectively discharged to either supplement the electric power supplied by the vehicle to the device or to completely power the device such that the device is provided with electric power for operation at a peak rate exceeding the nominal rate electric power is supplied from the vehicle to the capacitor and/or the device.

  • Patent number: 8011295
    Abstract: An automated bale wrapping control system for a round baler that includes a simplified remotely installable operator interface for installation on a tractor. The simplified operator interface includes manual operated, mechanical input switches for selecting system on/off, number of wraps, twine or net wrapper selection, manual extension/retraction of the wrapping mechanism, and/or manual wrap cycle initiation. An audible alarm provides feedback to the operator for monitoring the baling and wrapping processes and for alerting the operator to abnormal conditions in the baling and/or wrapping processes.

  • Patent number: 7920947
    Abstract: Apparatus and a method for monitoring the performance of control algorithms, providing a safeing subsystem for a vehicle, particularly an agricultural windrower, for determining when a controlled system such as the propulsion system is no longer tracking a reference input signal sufficiently well. An appropriate action can then be executed, such as outputting a fault signal and/or shutting down the controlled system. An exponentially decaying integrator can be used to monitor the tracking errors.
