I am wanting to VRD a 3 section 4740 drill all same rate with the ability to shut down 1/3rds. automatically . Currently using insight on a JD planter with Direct Command. Have used RIchardey John ,Deere, & Loup Seed monitoring devices in the past on drill with limited pop. success. AG leader informed me they cant read drill monitor eyes. Need advise ASAP! Thanks Tom V.
