ABSTRACT:
A spout aiming control system for a forage harvester includes a sweep mode wherein the spout is automatically moved to provide even wagon filling under certain conditions. A magnetic pickup senses rotation of the forage harvester feed rolls. A disable system prevents operation of the sweep mode unless the feed rolls are rotating faster than a threshold rotation speed. A warning signal is generated if the pickup signal indicates that the feed rolls are not rotating and the pickup has an open circuit condition.
