Abstract: A front attachment for an agricultural harvesting machine operates independently of rows of stalk crop to be harvested. The front attachment includes harvesting devices for harvesting the stalk crop, intake conveyor mechanisms extending across a width of the harvesting devices, snapping devices located downstream of the intake conveyor mechanisms in the direction of the crop flow and a cross conveyor located downstream of the intake conveyor mechanisms and snapping devices. In the arrangement, the cross conveyor and snapping device driven by a common drive train, the front attachment is prefabricated to enable retrofitting with a second drive train and the second drive train functions as the drive for a retrofittable chopping device.

Abstract: A front attachment for harvesting corn for use in a self-propelled combine harvester includes harvesting devices for grasping and guiding the corn stalks, for picking the corn cobs and for conveying the picked corn cobs. The front attachment has intake conveyor mechanisms extending across the width thereof, snapping devices disposed downstream of the intake conveyor mechanisms in the direction of the crop flow embodying snapping rollers rotating opposite to the direction of travel and a cross conveyor equipped with opposing auger sections. The cross conveyor draws harvested corn cobs together in the center of the front attachment and feeds them from there to a feed rake. The intake conveyor mechanisms and/or the snapping rollers and/or the cross conveyor are driven by a driven mechanism of the combine harvester, which driven mechanism is connected to a steplessly variable transmission.

Abstract: A front attachment for harvesting corn for a self-propelled combine harvester includes a snapping unit for separating the corn cobs from the remaining components of the corn plant. The snapping unit has snapping rollers that rotate in opposite directions. An overload clutch is disposed within a drive train of the snapping unit. A drive system is optimized in that an overload clutch is directly assigned to each of the snapping rollers.
