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. In the same way, the control arrangement is capable of automatically controlling the third actuator as a function of the operation of the second actuator so as to maintain a desired direction of flow of the crop from the spout during adjustment of the height of the discharge end of the spout.
In an agricultural harvesting machine including a crop discharging device comprising a spout having an inlet end mounted for swinging about an upright axis, tilted slightly in a rearward direction relative to a forward direction of movement of said harvesting machine, and also for pivoting about a horizontal axis, a first actuator for selectively effecting movement of said spout about said upright axis so as to adjust a height of a discharge end of said spout, and a second actuator for selectively effecting movement of said spout about said horizontal axis, and a control arrangement being coupled to said first actuator and to said second actuator, the improvement comprising:
