  • Agricultural piston bale press
    Patent number: 8683779
    Abstract: An agricultural piston bale press includes a pressing piston, a main driving mechanism, an intake device to take in crop material, and a stuffing device. The stuffing device includes a feed passage and a stuffing mechanism that has a tine arm supporting tines that can be moved along a stuffing trajectory, and a drive mechanism for driving the tine arm. The drive mechanism is configured to move the tine arm in a cyclic movement along a constant trajectory, and that the tines are movably supported on the tine arm so that the tines can be arranged in different positions with respect to the tine arm to follow different trajectories.

  • Round Baler with Scale and Moisture Meter
    Publication number: 20130160661
    Abstract: A large round baler equipped with moisture sensing apparatus and a bale scale to improve information useful in baling and using bales. Moisture sensing begins after the bale reaches a predetermined diameter. A history of bale weights is used to estimate how much tension to apply to a belt tensioner to achieve both a target bale weight and a target bale size.
