We get this question a lot. In our experience, if you are running a 12 row or less, you will not need any power supply beyond that supplied by your Tractor. Sometimes 16 row planters can also be ran without an alternator. However, this can depend on type of soil and type of tractor being used to plant. Older tractors may need the help of an hydraulic alternator. If you have questions, please consult a Graham Dealer.
Yes, our product is adabtable to many monitors. Our EPD are universal with AgLeader, Precision, Trimble, and John Deere monitors.
That is the beauty of our electric planter drive system. It makes old planters new. We can retrofit on any old planter you may be operating.
Our electric planter drives replace chains and sprockets that are controlled wirelessly from a monitor in the cab. Our electric drives eliminate all ground and hydraulic drives and eliminates most chains and driveshafts. They drive the meters installed on the planter. They operate on any installed meter including John Deere, Kinze, Precision, White, Case iH, Monosem, Kuhn, Gespardo and Matter Mac to name a few.
Yes, our EPD can be used with a 3rd party monitor with variable rate modules installed to do variable rate planting as allowed by that 3rd party monitor. Otherwise, you can purchase any one of our GrahamCommand products to control our EPD and obtain variable rate control on a ROW-BY-ROW basis.
Yes, a 3rd party monitor to control individual row population can use our product. Additionally, you can select any on of our GrahamCommand products to control individual row population.
Yes, a 3rd party monitor that has GPS capabilities can be used to control our EPD and implement prescription mapping.

You can view our current models supported by going to the SUPPORT section of our website and viewing “Planter Models” to check that your planter model is supported. If you don’t see your particular planter, please contact Graham. We will find or create a solution that allows installation of our system on your planter.
Yes, our GrahamCommand Pro monitor can be equipped with modules to control granular fertilizer or liquid fertilizer including prescription mapping, auto row shut-off, section control (Granular) and individual row (liquid) control as well as turn compensation. This feature is offered through our technology partnership with H-Tec Ag.
We utilize 12V hollow shaft electric motors. On our Graham Lite product, we use brushed 80 RPM electric motors. Beginning in 2016, our Graham Pro EPD System will utilize 80RPM 12V 80 RPM brushless electric motors with individual row control boards built into the motors with high power RF chips to allow each row to communicate with our Interface system to the Cab.
