  • Patent number: 11297765
    Abstract: A harvesting system includes a header pivotally attached to a combine. The header includes a center section to which a left wing and right wing are pivotally attached. A suspension system of the harvesting system includes first and second engageable states that enable dynamic wing behavior and reduce structural load. The first state corresponds to a harvesting configuration of the header in which the wings are allowed to pivot to allow the header to follow changes in terrain. The second state corresponds to a configuration in which the header is elevated relative to the ground. In the second state, the ability of the wings to pivot is minimized as compared to the first state, which allows the header to be maintained in a substantially flat configuration while minimizing the amount of dynamic load imparted by the header on the combine during non-harvesting transport of the header.

  • Patent number: 11064651
    Abstract: A disc opener unit for an agricultural implement has a down pressure adjustment device that automatically adjusts the amount of down pressure applied on a furrowing disc based on strain measurements taken by a strain gauge or load cell. The strain gauge, which may be mounted to an arm that is used to set the position of a depth setting gauge wheel, provides feedback to a processor that in turn controls the amount of hydraulic fluid in a hydraulic cylinder to adjust the down force applied on the disc. The amount of down pressure is therefore adjusted in substantially real-time in response to changes in field conditions, which improves furrow depth consistency and reduces wear on the gauge wheel and its components.

  • Patent number: 10774506
    Abstract: A system for moving material with a ground engaging work implement determines a topography of the work surface, a maximum cutting capacity for a cutting operation, and a maximum carrying capacity for a carrying operation. A first double cut location is determined based upon the maximum carrying capacity and the topography of the work surface and a second double cut location is determined based upon the maximum carrying capacity and a modified topography of the work surface. Individually, the amount of material from each of the first and second double cut locations is less than the maximum cutting capacity, and combined is less than the maximum carrying capacity. A first forward double cut command moves the first double cut material to an intermediate position and a second forward double cut command moves the first double cut material and the second double cut amount of material to a dump location.

  • Patent number: 10753755
    Abstract: A method controlling movement of an agent moving within an environment represented by a directed graph including vertices located at a border of an unknown portion of the environment, includes: guiding the moving agent via execution of at least one iteration of following successive operations: planning a path towards a destination vertex or border vertex, via a progressively increasing evaluation of a first heuristic of cost; controlling navigation of the agent towards the destination or border vertex returned by the planning; controlling an exploration in the unknown portion if the planning returns a border vertex as the destination. The planning includes, for each calculation of the first cost heuristic for a border vertex, calculation of a second heuristic of risk. The method provides, as the destination, the border vertex with lowest calculated heuristic risk evaluation as soon as the cost exceeds this heuristic risk evaluation before reaching the destination vertex.

  • Patent number: 10667461
    Abstract: A disc opener unit for an agricultural implement has a down pressure adjustment device that automatically adjusts the amount of down pressure applied on a furrowing disc based on strain measurements taken by a strain gauge or load cell. The strain gauge, which may be mounted to an arm that is used to set the position of a depth setting gauge wheel, provides feedback to a processor that in turn controls the amount of hydraulic fluid in a hydraulic cylinder to adjust the down force applied on the disc. The amount of down pressure is therefore adjusted in substantially real-time in response to changes in field conditions, which improves furrow depth consistency and reduces wear on the gauge wheel and its components.
