  • Publication number: 20230363317
    Abstract: An agricultural system includes: a frame; a control system operatively coupled with the frame, the control system including: at least one sensor configured for: detecting remotely at least one operative condition of a bale of a crop material after the bale has been ejected from a bale chamber of a baler; outputting at least one operative condition signal corresponding to the at least one operative condition; a controller system operatively coupled with the at least one sensor and configured for: receiving the at least one operative condition signal; determining at least one operative parameter based at least in part on the at least one operative condition signal, the at least one operative parameter being associated with a performance of the baler.

  • Publication number: 20200275609
    Abstract: An agricultural harvester is disclosed. The agricultural harvester comprises a header and a cab for an operator of the harvester. The header includes a frame, a support arm connected to the frame and a harvesting reel assembly. The harvesting reel assembly includes a central rotatable shaft connected to the support arm, a reel member extending widthwise across the harvesting reel assembly and connected to the central rotatable shaft for rotation therewith, and a first cam assembly rotatable about a first end of the central rotatable shaft. The first cam assembly includes a first cam plate, a first non-circular cam track for guiding rotation of the reel member and a first adjustor. The first adjustor is operatively engaged with the first cam plate and pivotably connected to the support arm for adjusting a rotational position of the first cam assembly relative to the central rotatable shaft.

  • Patent number: 10091923
    Abstract: An agricultural vehicle includes a chassis; a header carried by the chassis and including a cutter mechanism, the header being adjustable in a vertical direction; a swath roller carried by the chassis behind the header; a roller actuator connected to the swath roller and configured to adjust the swath roller in the vertical direction; and a controller coupled to the roller actuator. The controller is configured for: detecting when the header raises in the vertical direction; recording a header raising point where the header raises; determining when the swath roller reaches the header raising point; and signaling the roller actuator to raise the swath roller when the swath roller reaches the header raising point.
