No more fumbling through manuals or using the tractor's in-cab controller. Use the Duncan Seed Drill app on your phone for easy and accurate job configuration and calibration of any new or existing Duncan Renovator or Duncan Enviro drill, and take your drilling operations to the next level of productivity. The Duncan seed drill app contains step-by-step user guides for making calibration and mechanical adjustments to your drill. Great for any new operator or if you're just a bit rusty yourself! Calibrate multiple machines with the app, and get every operator set up with it too so they can do calibrations from their own phone. Calibrating a ground drive drill with seed or fertiliser will the display the required mechanical settings. Connect wirelessly to a Duncan E-Drive drill to set up the sowing rates and run calibrations while you are right beside the drill. Not sure if your Duncan E-Drive drill will connect with the app? Talk to your nearest Duncan dealer to find out more.
