  • Patent number: 11160216
    Abstract: A round baler includes a pick-up unit for picking up crop material from the ground, a baling chamber which receives the crop material from the pick-up unit, and a press mounted within the baling chamber for forming a bale during a bale formation cycle. The baler also includes a binding unit for dispensing a binding material for binding the bale, a tailgate displaceable by an actuator from a closed position at the beginning of a bale formation cycle to an open position to dispense the bale after the binding cycle. A sensor detects a first tailgate position after the bale formation cycle and before the binding cycle, and detects a second tailgate position after the binding cycle and before displacing the tailgate to the opened position. A controller is responsive to the sensor by determining a tailgate position change between the second tailgate position and the first tailgate position.

  • Publication number: 20200214219
    Abstract: A round baler includes a baling chamber and a press means mounted within the baling chamber. A first sensor is disposed within the baler for sensing data related to a change in a diameter of a bale being formed in the baling chamber. A second sensor is configured to detect data related to a speed of the press means, such as a rotational speed of a drive shaft. The data related to the change of the diameter of the bale and the data related to the speed of the press means after each rotation of the bale are processed to determine a thickness of a layer of the crop material in the bale. The thickness is indicated in a display unit for an operator to view.
