The Duncan mechanical drive system is tried and true, proven on thousands of machines spanning decades of production.

For simplicity, accuracy and reliability, our ground driven mechanical drive seed metering is pretty hard to beat. That's why we still offer it as the standard specification on all of our gravity box drills and small air seeders.

 Features include:

• Reliable jockey wheel ground drive
• Variable speed gearbox for each seed or fertiliser box
• Simple manual calibration process
• Can be upgraded to the Duncan Touch-Screen electric drive by simply swapping the drive pedestal assembly and installing the wiring loom
