The History of Duncan Ag

Founded in 1937 by Bill Clough, Duncan Ag began designing, developing and building swamp ploughs. From there, under the leadership of George Clough until 1993, the company went on to build up a solid reputation for strength, quality and innovation that's endured through to the present day.

"Duncan Ag is founded upon a solid history of quality and service to the
Agricultural Industry for more than 70 years."



Each of the machines that Duncan Ag manufactures are being continually created stronger and better using some of the world's best technology. New Zealand and Australia are benefiting from this process and are now producing some of the world's highest-yield pasture for all stock grazing applications.


Duncan Ag specialises in seed drills that are easy to set up and operate, are accurate in seed and/or fertiliser placement and distribution. The company is well-known for making superior equipment for feeding out baled hay and silage bales, equipment that works with minimum wastage and better feed consumption.


Duncan products can be relied upon to deliver reduced downtime, lower maintenance costs, longer machine life, and excellent resale value - and that means greater productivity overall.
