  • Publication number: 20260020525
    Abstract: A system and method are provided for proactively adjusting a height of an agricultural machine, or components thereof, using at least terrain elevation information provided by, or incorporated into, a terrain map. Moreover, the system can be configured for proactively determining a setpoint for the height(s) of the agricultural machine, or associated components, based a determination that involves at least one or more of a machine sink of the agricultural machine, a tilt offset of the agricultural machine, and elevation differences between a field and an adjacent headland, among other considerations. The system can further evaluate the time for the agricultural machine to reach a location, such as, for example, a location at which terrain elevation changes, an agricultural operation at least temporary stops or resumes, an end of a crop row, or a headland boundary such that such height adjustment(s) occur proactively, including in view of inherent system latencies.

  • Publication number: 20250098574
    Abstract: A basecutter assembly for a sugarcane harvester includes a cutting spindle powered by a first power source, and a transport spindle powered by a second power source independent of the cutting spindle. A torque sensor is coupled to the cutting spindle. A harvester controller defines a target cutting torque value for the cutting spindle based on a desired crop cut height and determines a current cutting torque of the cutting spindle while cutting the crop. The harvester controller may then control a height of the cutting spindle relative to a ground surface to maintain the current cutting torque substantially equal to the target cutting torque value to achieve the desired crop cut height.

  • Patent number: 11744180
    Abstract: A control system for a harvester that harvests crop stalks each having a bottom portion and a top portion. The harvester includes a topper that cuts the stalks between the top and bottom portions and a base cutter that cuts the stalks near a ground surface. The control system includes a sensor that senses a first height between the top of the bottom portion and the ground surface, and senses a second height between the bottom of the bottom portion and the ground surface. The controller receives signals representing the sensed first and second heights from the sensor, determines average first and second heights for the stalks over a set time, sends a first signal to the topper to cause movement of the topper to the average first height, and sends a second signal to the base cutter to cause movement of the base cutter to the average second height.
