Abstract
The crop discharge spout of an agricultural machine is continuously adjusted so that the crop material discharged therefrom is always directed into a wagon connected to the rear of the agricultural machine. A sensor disposed on the agricultural machine cooperates with a mechanical follower which is coupled therefrom to the wagon to provide a signal indicative of the angle between the agricultural machine and the wagon. The signal is compared with a signal from a second sensor indicative of the angle of the direction of the crop discharge from the spout with respect to the agricultural machine and an error signal is developed from the difference therebetween. The error signal is coupled to a motor which rotates the discharge spout accordingly until the error signal is reduced to zero.
