  • Patent number: 11375658
    Abstract: An agricultural system includes an arm that supports a cutter bar assembly and is coupled to a fluid-filled biasing member such that the fluid-filled biasing member imparts a torque onto the arm. The agricultural system further includes an actuator and a controller. The actuator is coupled to the fluid-filled biasing member and is configured to move the fluid-filled biasing member relative to the actuator to change the torque imparted by the fluid-filled biasing member onto the arm. The controller is configured to determine a target position of the arm associated with a leveled configuration of the cutter bar assembly, receive an input to set the cutter bar assembly in the leveled configuration, and output a signal to instruct the actuator to set the fluid-filled biasing member relative to the actuator based on the target position upon receiving the input to set the cutter bar assembly in the leveled configuration.

  • Publication number: 20210237982
    Abstract: A detection system for an agricultural header includes a belt that has at least one physical feature driven by a roller at a roller rotational speed. The detection system also includes a sensor that detects a physical feature as it passes the sensor during rotation of the belt. The detection system further includes a controller that receives a signal indicating a first pulse of a first time a physical feature passes the sensor during the rotation of the belt and a second pulse of a second time a physical feature passes the sensor during the rotation of the belt. The controller further determines a pulse frequency based on the first and second times and calculates a belt rotational speed based on the pulse frequency. The controller compares the belt rotational speed to the roller rotational speed and provides an output if the roller rotational speed exceeds a threshold.
