I have a flexicoil variable rate 3450 cart. It is triple tank with 3 VRA electric over hydraulic motors. I only have the standard monitor/control that can with it. Question is can I use mobile to control the VRAs. How many motors will mobile control. I want to variable rate 2 tanks. I can see doing all 3. Then, can I even make a prescription map for 3 VRA products at once with mapping?
