    摘要： A center knife drive for a sickle of a plant cutting machine having an upwardly facing cover and at least one output element reciprocatingly movable by the drive above the cover for moving a knife of the sickle in a sideward reciprocating cutting action, including at least one cleaning flap in connection with the output element positioned and configured for reciprocating forward and rearward movement thereby, disposed above the cover and configured for cleaning loose material therefrom during the movement and for pushing the loose material from the cover to accommodate upward movement of the drive within a space below or in a floor of the machine, clearing the material from the path of the output element, and improved heat dissipation.

    摘要： The pivoting action sickle drive has a low profile allowing incorporation in or below a floor of a header of a plant cutting machine to allow passage of cut plant material thereabout. The drive includes a substantially flat rotatable input element, and a drive arm connected eccentric thereto for eccentric rotation along an epicyclical path. The arm extends to a connection with a pivot arm of a pivot element that connects to a knife arm that drives a sickle knife assembly, such that the pivot element, knife arm and knife assembly will be reciprocatingly driven by the eccentric rotation of the drive arm. A second drive can oppositely drive a second sickle knife assembly, such that opposite forces generated by the drives will cancel. The drives can be packaged in a forwardly tapered or curved enclosure, and the pivot elements can be correspondingly shaped to streamline the drives.

    摘要： A header for an agricultural vehicle. The header includes a header frame and an elongate sickle knife mounted along a leading edge of the header. The header further includes an actuator for reciprocally moving the elongate sickle knife in its longitudinal direction relative to the header frame between a first position and a second position over an intermediate position. At least one accumulator extends between the header frame and the elongate sickle knife to accumulate energy during a first movement of the elongate sickle knife from the intermediate position towards at least one of the first position and the second position, and to release accumulated energy during a second movement of the elongate sickle knife opposite to the first movement.

    摘要： An agricultural cutting device has knife bar sections with section knife blades. A drive with phase offset drives the knife bar sections at least temporarily in opposite directions. The section knife blades interact scissor-like with counter knives. The knife bar sections have adjacently positioned bar ends. When the knife bar sections move, a gap of varying size is formed between the bar ends. A mowing finger is arranged at the gap. A stationary knife blade with first cutting edges is arranged at the mowing finger. The first cutting edges are arranged adjacent to the mowing finger and extend at a slant relative to a forward travel direction of the cutting device so that the cutting edges have a V-shaped arrangement broadening in travel direction. The knife bar sections have an outer knife blade attached to the bar ends whose cutting edges extend parallel to the travel direction.
