  • Agricultural harvesting machine with transfer device
    Patent number: 7873456
    Abstract: An agricultural harvesting machine, in particular a self-propelled forage harvester for picking up and processing crop material has a transfer device—which is located downstream from feeder and chopping devices and is swivelable around a horizontal and vertical axis—for transferring the crop material, and at least one dampening device—which is located between the vehicle body and the transfer device—for dampening the vibrations of the transfer device. The dampening device may be adjusted as a function of specified operating criteria in order to dampen the vibrations of the transfer device.
