  • Publication number: 20250331463
    Abstract: A pick-up attachment for a harvesting machine preferably for a field chopper, particularly preferably for a self-propelled field chopper, includes a pick-up rotor having pick-up tools for picking crop up from the ground, at least one guide element that rests on the ground, which element takes on the guidance of the pick-up rotor and guides it relative to the ground, and a machine frame that is connected to the pick-up rotor. The pick-up rotor is composed of multiple segments connected to one another at least partially in an articulated manner, for adaptation to the contours of the ground. At least one guidance system movably connects the pick-up rotor, in particular a segment of the pick-up rotor, to the machine frame of the pick-up attachment.

  • Publication number: 20250248339
    Abstract: A pick-up attachment for a harvesting machine, preferably for a field chopper, includes a pick-up rotor having pick-up tools for picking crop up from the ground. The pick-up rotor is connected to at least one guide element that rests on the ground and takes on the guidance of the pick-up rotor and guides it to the ground. The pick-up attachment can be tilted toward the ground and away from the ground by an angle that can be predetermined, about an axis of rotation transverse to the direction of travel, so as to set the raking height, in such a manner that the contact point of at least one guide element shifts during tilting, and thereby the position of at least one region of the pick-up rotor and thus the distance of at least one pick-up tool situated in this region or of the raking point from the ground changes.

  • Publication number: 20250098588
    Abstract: A pick-up attachment for a preferably self-propelled forage harvester includes a pick-up rotor with pick-up implements (for picking up crops from the ground, wherein the pick-up rotor is assembled from several segments joined to one another in at least partly articulated relationship for adaptation to the contours of the ground.

  • Publication number: 20250017143
    Abstract: A pick-up attachment for a harvesting machine includes a pick-up rotor having pick-up tools for picking crop up from the ground. The pick-up rotor is connected to at least one guide element on the ground that guides the pick-up rotor to the ground. The pick-up rotor along with the at least one guide element is suspended on the machine frame of the pick-up attachment by control arms, so as to swing. Each control arm is connected to the pick-up rotor with one end, in an articulated manner, and to the machine frame with the other end, in an articulated manner, so that during push travel of the pick-up attachment, a push point forming the attack point of a thrust direction vector defined by the control arms is arranged below the contact point that forms between the ground and the guide element, when the pick-up rotor assumes a certain position.
