We are trying use 4 hydraulic drive motors to control 4 sections on a 12 row 1720 JD planter. We are using a 2600 display and have seed star 2 on the planter. Not sure if John Deere ever uses 4 motors and my dealer isn't either can't find much info anywhere. Dealer says i need a GS rate controller. Anyone had any experience
GS2 Rate Controller
