Laurie Brownlee a retired farmer came with an invention called the Full Bin Sensor, which attached to the spout of a grain auger. The sensor sets off an alarm and light to let farmers know when the grain bin is getting closed to full. The unit gives the farmer plenty of warning to shut the flow of grain down to avoid plugging the auger or spilling any grain. It can be easily installed on any type of grain auger. At the time of our visit it was selling for $699. Brownlee has also built the Hopper Dropper, which allows farmers to open hopper bottom bin chutes wide open without spilling any grain. The unit attaches to the bottom of the bin with 80 pound magnets and sells for around $249.00.
