Graham offers a module upgrade to our Graham Pro EPD system that allows operators to control dry and liquid fertilizer application through our GrahamCommand Pro tablet-based controller.

Liquid Fertilizer Control Module includes:
NOTE –Each Graham Pro EPD motor provides power to individual row PWM solenoids (must be purchased from 3rd party seperately). Each PWM solenoid offers variable rate flow control and is wirelessly controlled through each motor control board housed in the end cap of each Graham Pro motor.
