The Legend ST

Seed Sensor

LEGEND sensors continue to operate in spite of wiring problems, thanks to two-way daisy-chain communications. There are no obstructions to seed flow and they automatically compensate for build-up of seed treatment.

Product Information


Our accurate optical sensors use infrared energy to detect seed flow, much like a motion sensor in a security system. There are no pins or plates to interfere with the seed path. Each sensor has its own intelligent electronics to determine its order in the system. This means simple hookup compared to systems where you have to connect several boxes cluttering the machine. We have improved the ‘Daisy-Chain’ connection system so that a disconnected cable has no effect on operation.


Our sensors are built with a stainless steel tube which is nearly indestructible. Our cables and connectors have been proven to withstand vibration and moisture. Each sensor is tested with extremes of temperature. Six sizes of sensors are available for inside hose diameters of 22, 24, 25, 30, 32 and 38mm.


Our seed flow sensors are the world’s best, based on durability, ease of use, accuracy and value.

Air Drill Rate & Blockage Monitor

Applying too much seed or too little seed can be a costly mistake. Knowing the seed population is something corn and soybean planter operators have enjoyed for years. Now, air drill operators seeding small grains (or large!) can benefit from this information. Even a single plugged run will justify investing in THE LEGEND. This year, your Crop’s Story won’t include a tale of missing strips!

Blockage Monitor

Our entry level Air Drill Blockage Monitor requires minimal setup, and uses the same great Stainless Steel sensors. Audio and visual blockage alerts are provided. Flow information helps find meter or air system faults. Heavy duty weather proof harness is used throughout.

The Agtron ART-100 is an advanced blockage monitor developed by Agtron Enterprises for use on conventional type air seeders and air drills. The Monitor system consists of "smart" seed flow sensors and heavy duty weather proof cabling. The ART-100 automatically loads the sensor configuration.
