  • Publication number: 20260033434
    Abstract: A baler has a dispensing arm movably mounted to a frame and configured to dispense twine to wrap a bale of crops. The bale has a first end, a second end, a center, and a rotation axis extending along a longitudinal axis of the bale. The twine arm is moveable between a stowed position, a first position near the first end of the bale, and a second position near the second end of the bale. A controller is operatively coupled to the dispensing arm to control movement of the dispensing arm between the first end, a first and second catch position, and the second end. The controller is programmed to move the dispensing arm with a fast stroke at portions of the bale and a slower apply stroke a different portions of the bale to wrap the bale with twine having consistent spacing along the longitudinal axis of the bale.

  • Patent number: 12477995
    Abstract: A method of monitoring a status of a supply of wrap material of a baler implement includes receiving a supply roll length input when a new supply roll of wrap material is loaded into a wrap system of the baler implement. A respective length of the wrap material used to wrap each bale since receiving the supply roll length input is determined and summed together to define a total current used wrap value. The total current used wrap value is subtracted from the total longitudinal length to define a current remaining length of the wrap material. A notification signal is communicated to a communicator to indicate to an operator the current remaining length of the wrap material on the supply roll of the wrap material.

  • Publication number: 20240295467
    Abstract: A baler comprising an accelerometer coupled to the frame and configured to output a bulk signal representative of the total vibrational power in the frame, and a controller in operable communication with the accelerometer, where the controller is configured to deconstruct the bulk output signal provided by the accelerometer into at least a first component signal and a second component signal, and where the controller is configured to associate one of the first component signal and the second component signal with a first bearing and the other of the first component signal and the second component signal with a second bearing.

  • Patent number: 10588270
    Abstract: A baler including a frame, a compression system coupled to the frame, the compression system at least partially defining a compression chamber, a feed pan at least partially defining a pre-compression chamber, where the pre-compression chamber is in operable communication with the compression chamber, a first driven output shaft rotatable about a first axis of rotation, a second driven output shaft rotatable about a second axis of rotation, a lifting fork movable with respect to the pre-compression chamber and at least partially positionable therein, where rotation of the first driven output shaft, the second driven output shaft, or any combination thereof causes the lifting fork to move with respect to the pre-compression chamber, and where the first driven output shaft is operable independently of the second driven output shaft.
