  • Patent number: 10225985
    Abstract: Pick-up devices of a forage implement such as a round baler may include stripper bands that define slots between the stripper bands to allow tines to pass through during rotation of the tines. The pick-up device may include a back-plate for attaching stripper bands that includes chambers to receive the bands.

  • Patent number: 7490544
    Abstract: In a round baler, twin arms come together in the start position, on the side opposite the cut position, because that configuration ensures that two twines lie nearly on top of each other to secure the bale much better at that end than with a single twine. The “start position” refers to that position where the twine arms reverse direction, and change from a fast speed of travel used to move the twine arms across the bale width, to a slower, controlled speed that is adjustable to vary the spacing of the twines. The change in direction combined with bringing the twine arms together at the start position, ensures that loose twine ends are effectively restrained as the twines are applied.

  • Patent number: 6925788
    Abstract: A reverser which, in a preferred embodiment, has a hydraulic cylinder supported by a chopper baler frame. The opposite end of the hydraulic cylinder is attached to the reverser driver. When activated by hydraulics on a tractor, the hydraulics will extend the cylinder, causing the sprockets to be disengaged. Further extension of the cylinder will cause the reverser driver to engage the reverser sprocket and turn the rotor backwards slightly. After full extension, the cylinder will then be retracted. This process can be repeated a couple of times in order to remove the blockage. The reverser enables the operator to restore the baler to its working condition from the tractor seat. Being able to disengage the rotor from the rest of the machine enables the bale to be wrapped if a major blockage occurs. Also a controlled reversing motion is beneficial, so over-reversing does not occur.

  • Patent number: 5822967
    Abstract: An apparatus for forming and wrapping round bales includes a baler, arm structure, a cradle, and moving structure. The baler is for taking in a crop material, forming the crop material into a bale, and ejecting the bale. The arm structure is connected to the baler. The cradle is pivotably supported by the arm structure and is for holding the ejected bale. The cradle includes rotating structure for rotating the bale about a central axis of the bale. Moving structure is for providing relative movement between the baler and the cradle. Wrapping structure is supported by the baler and is adapted for holding wrapping material. The wrapping structure is movable around the bale and cooperates with the rotating structure to be capable of wrapping the bale with the wrapping material.
