Why do you still have the wheels inside the frame?

Because the bar simply works better. The design allows plenty of space between rows to reduce stubble blocking and maintains frame geometric balance between the front and rear tines.

Why did you retain the rigid drawbar?

For strength, stability and reduction of crabbing with controlled traffic.

Doesn't that mean that you get poor ground following characteristics and therefore poor depth control?

No. The attributes of so-called flexible frames and floating hitches are an integral part of our patented DBS seeding modules. We need a bar that is a strong carrier for our modules. That's why we keep it simple. The DBS modules are designed to achieve the required ground following characteristics for precise seed depth. That's why we call our Auseeders 'Precision Seeders'.

What about weed control using DBS?

Incorporated chemicals have been shown to give effective weed control and most DBS owners claim reduced post chemical usage. We believe the chemical incorporation and fast germinating crop plants play a major role in inhibiting weed plant growth.

Should I be using narrower row spacings?

Wider row spacings, 260mm (10") – 300mm (12"), in a systems approach are outperforming conventional practices. Wider row spacing means less weed seeds are stimulated to germinate, putting less pressure on weed control strategies and at the same time utilising the increased benefits of water harvesting.

What do you call precision seeding?

Seed placed into tilled soil at the required depth with absolute minimal variation. This is achieved with our patented DBS Three Slot System, with each slot having its own unique environmental characteristics to assist early vigorous plant growth that sets up yield potential. The first slot breaks through hardpans to create moisture and air pathways, the second slot places the seed at a precise depth in disturbed but stabilised soil while the third slot is more commonly described as the water harvesting trench.

What about 10" Spacings when swathing or growing hay?

Problems associated with windrows settling can be reduced by cross-swathing- i.e. swathing in a different direction to seeding.

Does DBS require more horsepower?

Using a 5" DBS blade there should be little difference from using conventional knife points, although 7" is the preferred blade length. Comparisons made between DBS Auseeders and other machines often don't allow for the Auseeder's ability to work deeper and in more difficult conditions.

But won't the trenches encourage water-logging?

As a general rule, water harvesting trenches are critical in capturing any available moisture, be it from showers, dews or rain events, particularly in water repellent soils. Infrequent "deluges" are the exception. However, the interow soil has the ability to absorb much of this excess water. In addition, the ability to break through hard pans allows excess water to move away from the seed in extremely wet conditions.

How does the DBS perform in gravel and clay?

The excellent penetration of the DBS tine allows sowing in even the tightest clay soils and the controlled hydraulic return allows the DBS to cope with gravel soil types. The three slot system has shown excellent results on all soil types.

Can I get over my paddock for spraying in a wet season?

The unbroken soil in the interow supports passing machinery making post seeding spraying easier.

Can I re-seed after flooding rain?

Yes. The DBS system has the advantage of the soil in the interow maintaining firmness and good trafficability.

Why do you claim your system of seed establishment is superior to other seeding systems?

We don't make such claims because we believe our DBS, unique as it is, remains a part of the overall system. Well planned agronomic programs and paddock management are also integral for successful cropping. What we do claim is that in this "systems" context, using a DBS precision seeder will enhance: 

  • Depth control
  • Seed germination
  • Plant density
  • Seedling vigour
  • In-crop weed control
  • Soil moisture retention
  • Soil structure and fertility
  • Seed plumpness meaning less screenings and higher hectolitre weights and
  • More consistent crops and higher yields
