Abstract: A machine for cutting and chopping corn and similar stalk-like harvested crops independently of rows includes drawing-in and cutting drums which are overlapped on the upper side in the region of their rotational sector by cover plates which interact each with a divider point for the harvested crops to be cut. The divider point extends in the driving direction. The outer edge of the cover plates in the region adjoining the respective divider point has an arching counter to the driving direction. The arching exposes the driving teeth of the associated drawing-in and cutting drum and forms an opening for the entry of the harvested crop between the driving teeth. This opening can optionally be closed by means of a blocking element depending on the nature of the crops being harvested.

Abstract: The mowing implement of a mowing apparatus, rotating about a vertical axis, is driven over a transmission comprising a freewheel mechanism and driving pins. A drive shaft is connected with the freewheel mechanism so that there cannot be any mutual rotation therebetween. In a basic orientation parallel to the axis of rotation of the mowing implement, these driving pins produce a driving connection between the freewheel mechanism and the mowing implement for driving the latter. In the event of a stoppage of the drive shaft, the driving pins, together with the freewheel mechanism, carry out a lifting motion, which interrupts the driving connection between the mowing implement and the freewheel mechanism. During their lifting motion, the driving pins activate a braking device in the region of the interior of the transmission housing above the freewheel mechanism. This braking device rapidly brings the mowing implement, which continues to run, to a stop.

Abstract: In the case of a machine for mowing and chopping corn and other similar stalk-like harvested crops, independently of rows, with at least two drawing-in and mowing drums disposed on either side of the vertical, central longitudinal plane of the machine, the cut, harvested crops are supplied to a central chopper over conveying ducts comprising vertical guiding walls. Towards the chopper and in plan view, the guiding walls have the shape of a wave traveling at right angles to the longitudinal, central plane of the machine. As seen in the driving direction, in each region of the wave crests between two adjacent drawing-in and mowing drums, a transverse conveying drum with protruding driving teeth is provided. Through opening slots in the guiding walls, the driving teeth intervene in the conveying duct for the cut, harvested crops.

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.

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.
