The 3 metre to 4 metre rigid Renovator AS air seeders are highly optioned drills made for large farmers and contractors.
Featured with large easy access 700 litre seed and fertiliser hoppers and reliable and robust fluted roller metering units.
The AS drills use a large hydraulically powered fan to ensure consistent air supply on the flat plains and steep slopes.
Strong 25mm coil tines with Baker boots will place the seeds in the ground at the right depth and encourage a quick and even germination.
Often fitted with electric drive, the operator has full fingertip control of the sowing rate and constant monitoring of the hopper levels, fan speed, ground speed and hectares sown.
For an operator who strives for the best results, the AS drill is the machine for the job.
Small to Large
- Large capacity split hopper for both seed and fertiliser
- Large platform and safety rails that can be installed on either side of the machine, enabling easy access and safer loading of the hoppers
- Superior trash flow
- Seed and fertiliser is delivered by air with Accord metering for improved placement
- Butterfly valve for controlling different air rates between bins
- Ground driven jockey wheel
- Nihard inverted ‘T’ point with Tungsten leading edge
- 25mm coil tines
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.
25mm Coil Tine
The tine has minimal sideways movement so that it tracks straight and it will follow an opening disc.
The tine pulls back before it lifts up out of the ground, so it is not placing seed on top of the ground.
Made from solid spring steel with no drilled holes to weaken it so it’s very durable with minimal breakages.
Staggered tine mounting layout to assist trash flow.
The Baker Boot is replaceable.
The tungsten carbide leading edge with a positive rake angle on the point penetrates the ground and opens up a slot.
The seed and fertiliser are placed at different depths for optimum germination.
The wings & heel of the boot create a cavity containing all of the key ingredients being seed, fertiliser, moisture, air and loose soil which is ideal for fast germination and rapid root development.
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.
