  • Crop cutting device, agricultural machine comprising such crop cutting device and crop cutting method
    Patent number: 11266073
    Abstract: A crop cutting device including knives pivotally mounted below a crop guiding surface. Each knife is pivotable between a retracted position in which it is located below the guiding surface and an extended position. At least a cutting edge of the knife projects above the surface. A selector mechanism selectively holds spring loaded parts of operating members to maintain the corresponding knife in its retracted inoperative position while the operating member is moved to its second position. The selector mechanism includes a shaft carrying a plurality of cam elements which are mounted on the shaft and arranged to be moved to a position for blocking a respective spring loaded part upon rotation of the shaft from a non-holding to a holding position.
    Type: Grant

  • Support wheel assembly for a pick-up of an agricultural machine
    Patent number: 9723788
    Abstract: The assembly comprises a beam, a support wheel rotatably mounted on an axle carried by the beam with a stub shaft. A hole in the frame of the baler which receives the stub shaft includes at least one radial recess dimensioned to permit the radially projecting arm to pass through the hole when aligned with the recess, the arm preventing the stub shaft from moving axially relative to the frame when misaligned with the recess.
