  • Publication number: 20040173435
    Abstract: A crop discharging device, such as a discharge spout for a crop chopping machine, has a crop input end mounted for swiveling about an inclined upright axis and for pivoting vertically about a horizontal axis. The discharge spout also includes a vertically adjustable flap at its discharge end for directing the flow of crop from the spout. A first actuator is provided for effecting movement of the spout about the upright axis, a second actuator is provided for effecting movement of the spout about the horizontal axis and a third actuator is provided for effecting movement of the flap. A control arrangement, which includes a memory into which a preset correlation table, or the like may be loaded, is provided for automatically controlling the position of the second actuator as a function of the position of the first actuator so as to maintain a given discharge height.
