ABSTRACT:
A crop-receiving wagon is pivotally attached to a forage harvesting machine with a pivotal crop discharging spout. A dual sensitivity spout-aiming control system maintains the spout-wagon angular relationship within first and second ranges during first and second ranges, respectively, of wagon-machine angles. A switching circuit switches the control system between its sensitivity modes in response to changes in the wagon-machine angle and includes a timer which delays the mode switching for a certain time period after a predetermined change in the wagon-machine angle. A gate circuit cooperates with the timer to reduce the delay period upon manual positioning of the spout.
