Daybreak Airseeders

With the development of high-speed conservation tillage implements, airseeders have needed to increase in delivery capacity.

Over the last decade, Daybreak Equipment has been developing an airseeder system that can deliver large quantities of product accurately and consistently.

The Daybreak twin roller system has many features that differ to peg or cog tooth systems. The most important is positive displacement of grain into the air stream.

The Twin Roller System:

The rollers support the grain and as they counter rotate, carry the product under a cut off plate, depositing the product into the air stream.
A hat sits inside the bin above the meter to carry the bulk weight of the seed, thus letting a constant weight and flow of grain pass through to the rollers irrespective quantity of product in the bin.
To resist corrosion the meter housing and all components including bearings are made of stainless steel or polyurethane.
There are two roller styles that each have a different groove pattern to suit the application of a wide range of products.

The hydraulic drive system has been developed to render the meter free of adjustments. A specialised low speed Durolla motor is direct coupled to the meter.

The meter has a range of 2-150 revolutions per minute.
A state of the art computer controller reads ground speed by accessing tractor radar or by a wheel sensor. It then controls the hydraulic motor speed through a proportional hydraulic control valve. This system provides variable rates as a result of yield mapping. It also provides instant sowing rate changes.

The bins are fabricated from zinc sheeting, with stainless steel bins available for use with liquid fertilisers. The bins are designed with full curve sections wherever possible. This design increases strength and improves filling capability.
