Enviro DD drills are an accurate, robust double disc air seeder, boasting low maintenance with few moving parts, and can penetrate the toughest conditions, while being easy to set up and operate.
Each vee-shaped double disc assembly has a leading 380mm diameter scalloped disc which cuts through trash and establishes a tilth while making a slot in the ground. The paired plain disc holds the slot open for the seed and fertiliser placement. A following press wheel, roller or harrows are used to close the slot, trapping moisture which is essential for enhanced germination.
Dual 1200 litre hoppers with optional hopper extensions increase productivity and reduce downtime.
The folding DD drills come in 4.5m, 5.0m and 5.5m widths. Options include press wheels, wide tyres, lube systems and cranes for loading bags. This is an incredibly versatile disc drill ideal for large scale farmers and contractors.
Small to large
300Ha plus
The heavy duty 2 point hitch gives excellent manoeuvrability, reduced overall drill length and allows for fine depth control using the tractor linkage arms
Double disc system with ground following ability. The leading 380mm scalloped disc cuts through trash and disturbs the soil enough to create tilth promoting faster germination. The combination of scalloped and plain discs in "v" sets create a slot for the seed and fertiliser placement.
Flexible HDPE scrapers clear mud and trash from between the double disc assemblies so that seed and fertiliser keeps flowing freely for even planting
The spring-loaded design allows the discs to closely follow ground contours, while stones are rolled over rather than being pulled out. Greasable, replaceable brass bushes in the pivot points help extend the machine’s service life
Sowing depth is adjusted by raising or lowering the transport and wing wheel sets. The is done with hydraulic rams and set using stop collars.
The high speed hydraulic fan is powerful to distribute seed and fertiliser evenly to the planting discs, even on steep slopes. Airflows can be increased for heavy rates of fertiliser, or reduced to eliminate seed bounce.
An oil cooler mounted on the fan inlet cools the tractor's hydraulics and utilises the heat to warm air going to the seeder distribution heads to prevent moisture plugging. The oil cooler has an over pressure valve and pressure gauge and uses a specially designed aluminium matrix core to utilise 100% of the air going into the fan.
Twin hoppers for seed and fertiliser. 1200L each side to carry a 1T bulk bag. The airflow distributor heads are installed inside the hoppers for a compact design that keeps them out of the weather
Large loading/access platforms at the front and rear with safety rails and lots of room for extra seed bag storage
The metering units are powered with 12V DC brushed motors through a reduction gearbox. This provides smooth variable speed control with loads of torque for heavy sowing rates, and fine control for low rates below 1kg/hectare
Accord style metering system - proven and highly accurate - essential when working with high value seed and fertiliser. It handles a wide range of products, from fine seeds at 1 kg/ha to peas at 350 kg/ha, and everything in between. A user-friendly trapdoor allows for quick and easy emptying of leftover seed and fertiliser.
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.
