Vanguard designs and builds custom wiring harness for agricultural equipment as well as providing a full line of electronic monitor accessories and repair parts. In 1992, Agri Motive Products introduced the first Grain Drill Monitoring System on the market, The Vanguard System.  Population monitoring was pioneered in 1994, and in 1998, the Precision Information Center was first on the market with Ultra High Rate Sensors for counting wheat and other small grains.  

With over 40 years of seed monitoring experience, The Vanguard System no provides more information and more capabilities in a non-population monitor.

Bar graphs show both high and low flows for each row.  At a single glance, the operator can see total performance of his system.  Switch to the new line graph, and a single row becomes the focus with a 20 second history to detect skips and doubles.  Min-Max-Average mode lets the operator know exactly how his planter is performing.

The Vanguard VM-4000 series monitors are totally new from start to finish.  They feature new concepts designed by engineers who know farming.  The economical VM-4100 is a 16 row monitor that is plug and play for seed monitoring only up to 16 rows.  Even the monitor harness is designed to connect to any common planter or drill harness, either a standard pin configuration or a John Deere pin out. That’s a feature found on only the VM-4100 to make it the simplest and easiest monitor to install and use.

The VM-4200 and VM-4400 include many additional features for the operator who wants to know more about the performance of his planter or drill.  It's easy to set-up and easy to operate.  

The VM-4600 is a 32 row monitor that is capable of monitoring up to 32 rows of flow and/or seed.  

With the new Visu-Flo Technology, you can monitor liquid flow directly from the screen. Do away with floating balls and welcome on-screen monitoring that offers so much more information to the operator.  Our unique flowmeter provides not only flow/no flow information, but GPA rates, and gallons applied.
