ABSTRACT:
Agricultural vehicles, such as a forage harvester, have been equipped with metal detectors. The metal detecting device is connected to stop the feed roll mechanism in a fraction of a second. In connection with this, it is important to shift the associated feed roll drive from a forward mode to a neutral mode. Such shifting, if done manually, may involve a delay sufficient to permit the harvester head to jam with crop material. Jamming is avoided by apparatus for automatically declutching a gear selector thus almost instantaneously shifting to the desired neutral mode in response to actuation of the metal detecting device.
