Which drill is right for you?

Duncan Farmer Drills

Planting on your own land at the right time makes a lot of sense. We offer a range of Renovator tine drills and Enviro disc drills to suit every terrain and budget. Tine drills make great economic sense, with a lower initial investment and reduced ongoing maintenance costs than disc drills — without compromising performance or germination rates. If you're working stony ground or dealing with heavy cover crops or trash, a disc drill could be the right solution. Explore our Farmer range to find what's right for you.

Duncan Contractor Drills

The Duncan name is famous for tough gear and it's been a favourite with contractors for decades. We have a heavy duty tine, double disc or triple disc air seeder that is perfect for your large-scale farming or contracting business. Customise it with a range of options to suit your operation and conditions.

Our reliable metering system has been utilised on Duncan Drills for years. It is easy to calibrate and use, requires no tractor hydraulics to run it and it is incredibly accurate due to the seeds being metered from individual outlets for each run, with sowing rates of less than 1kg/hectare achievable.

Seed and fertiliser is stored in boxes above the drilling discs and drops into the metering peg roller system for each run, with paired large and fine seed wheels, and flow control flaps to handle different seed sizes and sowing rates.

The metered seed and fertiliser then drops down flexible hoses to be planted.

Each run outlet is metered individually providing a high degree of accuracy. Shutter slides at the top of each metering device are used to control the seed flow entering the metering unit and can also be used to shut off a seed row if it is not required. All the box shafts and drive shafts are made from stainless steel for corrosion resistance and longevity.

The calibration tray collects the seed when calibrating and conveniently is used to cover the metering units to stop any foreign matter entering the metering unit in operation.

A stainless steel agitator shaft runs in the base of each box to eliminate compaction and bridging, and improves the flow of fertiliser and seed into the metering units.

Adjustable flaps control the outlet flow of seed and fertiliser from the metering unit.

Our system of dual large and fine metering wheels allow for a wide range of seed types and fertilisers to be used. Disconnecting the large wheel with the supplied tool lets you sow small seeds at very low rates under 1kg /hectare.

Engage the large wheel for larger cereal or grass seeds and fertilisers at high rates, still with a high degree of accuracy.

Our air distribution systems consist of a high-speed hydraulically powered fan, which blows air through a venturi system and distributor heads out to the ground engaging components, which are either discs or tines. Seed and fertiliser is metered out of the storage hoppers and drops into the passing airstream.

The fan has an oil cooling radiator mounted to the suction inlet which warms and dries the air to minimise blockages in humid conditions.

Air distribution is excellent on hills, uneven terrain or smooth worked ground because the seed is always being blown to the ground, rather than relying on gravity, chatter and hose vibration. The air hoppers are typically larger than the gravity boxes so they are easier to fill, and air seeders can be wider than gravity drills and easily folded up to a transport width.
