The Graham Electric Planter Drive (EPD) fits most planters to provide rate and section control.  Graham EPD’s integrate with your existing Trimble Field IQ system to provide individual row shutoff thereby reducing seed costs.  With Field IQ, you can also vary the rate across the planter.  When used with the Graham Command Pro tablet, you get individual row control, individual row shutoff and turn row compensation.  For example, it effectively turns a 24 row planter into 24 individual planters controlled by the Graham Command Pro.  Most rate controllers can take up to 80 feet to adjust the rate but with Graham EPD’s, the change happens within a foot of travel.  The Graham EPD system fits John Deere, Case, Kinzie planters and are easy to install.
