Abstract: A tuber planter employing a conveyor with feed cups to discharge seed tubers into a furrow and having an electromagnetic monitor thereon to signal the continuous operation of the conveyor is disclosed. The monitor comprises a permanent magnet protectively encased in a cover attached to a sprocket of the continuous conveyor which it monitors. A reed switch activated by a permanent magnet is protectively located adjacent to said sprocket. A housing preferably encloses at least a portion of the sprocket. The permanent magnet triggers the reed switch once each revolution of the sprocket so that an electrical signal sent from the reed switch to a remote location is interrupted or an electric signal can be intermittently generated by closing of the switch so that the operation of the continuous conveyor may be monitored, e.g., by a flashing light from a remote location.

Abstract: A crop conveyor assembly having regularly spaced flights and discharge means to minimize bruising is disclosed. A crop conveyor having a feed section and a discharge end is equipped with regularly spaced flights wherein said flights have upright, regularly spaced, flexible fingers. Discharge means to minimize crop bruising is located adjacent the discharge end of the conveyor. The discharge means comprises slender, spaced members through which the fingers of the flight pass as the conveyor changes direction at the discharge of said conveyor. Disk members attached to a common axle perform well as the discharge means.
