ABSTRACT:
A device for sensing the loading on an input drive of a cotton harvesting unit and providing a warning when an overload of the drive occurs. Normal tension in the belt drive to the unit input shaft is balanced by an adjustable spring load. Overload of the input shaft overcomes the spring load to activate an electrical switch that alerts the operator by lighting a warning lamp. The input drive includes a slip clutch, and the spring load is adjusted so that a warning is provided before the drive load reaches the loading which would cause the clutch to begin to slip.
