These Enviro DD models are folding versions of the DD30. Perfect for large scale farmers and contractors. These machines are easy to set up and operate, and the folding frame ensures that it is wide at work and narrow to transport. An extensive list of options including press wheels make these very versatile drills.

Technology
Air seed distribution
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.

Double disc technology
Lower investment cost than a triple disc drill and lower maintenance costs with less wearing parts.
Large 380mm diameter heat treated discs work hard and have a long life.
A scalloped disc leads 30mm ahead of a plain disc to cut through trash and open up a rough slot creating tilth for good germination. The (full assembly) leading scalloped disc removes the need for an opening disc.
The plain disc holds the slot open to place the seed and the fertiliser into the slot.
The spring loaded jump assembly creates downward pressure but also allows the discs to ride up and over rocks and obstacles.
An optional press wheel or harrows close the slot to help with seed to soil contact and traps moisture.

Duncan touch screen electric drive
All DD45, DD50 and DD55 drills have our high torque electric drives and a touchscreen electronic rate control. This advanced system is simple to use and gives the user instant feedback about the operating state of the drill.
Packed with features, including:
* Precision and flexibility to vary planting rates electronically
* Fingertip calibration adjustments
* Includes touch-screen control for turning planting on and off
* Checks drilling rates and areas planted in real time
* High torque electric motor drives and reduction gearboxes
* Visual and audible warnings of drilling rates and bin levels
* Transfer job data between the field and the office using a USB port
Add a GPS aerial for coverage mapping, record keeping and proof of planting.

Calibration App
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 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.
