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. The device is especially useful for tuber planters and the like wherein a planter is trailed behind a tractor and the display device for the monitor is mounted on the tractor so that the tractor operator will know that the planter is operating.
