  • Patent number: 5237804
    Abstract: A machine for mowing and chopping corn and similar stalk-like harvested crops includes at least two drawing-in and mowing devices which rotate about vertical axes and which are disposed on either side of the vertical, longitudinal midplane of the machine ahead of a chaff blower and, in each case, form several cutting sites. Push-in rollers, which form an inlet gap for the harvested crops, run in a horizontal plane lying at a distance above the working plane of the drawing-in and mowing device and are disposed ahead of the chaff blower for the purpose of charging it with the cut harvested crops.

  • Patent number: 4594842
    Abstract: A machine for the mowing and chopping-up of maize or the like should be able to operate independent of the distance between rows and the direction of the rows of the material to be harvested, and should also be able to pick up in a perfect manner stalks that have been flattened. To this effect one or several rotating drawing-in and mowing devices (6, 9) are arranged in front of a chaff-blower (1) with feed rollers (3), which drawing-in and mowing devices (6, 9) each comprise several cutting points (15;56) with adjacent working widths distributed over the front operating range. The drawing-in and mowing device positioned closest to the feed rollers at the same time acts as a transfer element for the harvested material coming from the cutting points arranged further away.
