  • Patent number: 5079906
    Abstract: The invention relates to a mowing machine provided with a hollow frame beam and with a plurality of mowing devices supported by the frame beam. The mowing devices are rotatable about axes of rotation extending upwardly and parallel to each other and can be driven by way of a driving belt provided in the frame beam and pulleys, located in the frame beam, which are coupled to the mowing devices. The axes of rotation of the mowing devices slope upwards during operation, when seen in the intended direction of movement, relative to a vertical plane extending in the direction of movement. Stubs are secured to the bottom plate of the frame beam, on each of which stubs there is journalled, by way of bearings a driving mechanism secured to a mowing device.

  • Patent number: 4566258
    Abstract: A rake for working crop lying on the ground having a pair of rotary rake wheels rotatably driven by gear boxes mounted at the ends of the frame beam. The first rake wheel is fixed to the frame beam, while the second rake wheel is mounted on a pivotable arm. The second rake wheel is so designed that it can be attached in two working positions. In the first position the rake wheels are transversely aligned to the direction of travel and driven in opposite directions so that the crop is direct between them. In the other position the rake wheels are located obliquely one behind the other and driven in the same direction so as to direct the crop to one side of the rake.
