FEW PIECES of machinery are more important to a grain grower than a seeding bar and cart, or air seeder. Depth of seeding, row width, seeding and fertiliser rates all play a key role in the successful germination of a crop and the air seeder is a vital part of the equation when it comes to getting your crop off to a good start.
In this report we take a look at the most popular brands of air seeder carts (by number) from the Kondinin Group's National Agricultural Survey. As well as a few key issues you should look for when buying an air seeder. While the air seeder is without doubt one of the workhorses of modern grain farming, subject to thousands of hectares of toil, the modern versions are not only robust, but highly accurate and intricate bits of gear.
On the surface, it's a large bin, or several bins, with a bunch of hoses, a few fans, some metering gear and wheels. But there's a whole lot of technology and engineering which goes into an air seeder to make sure it can cope with everything from canola and lupins to mono ammonium phosphate. Its job is to accurately measure and deliver a particular amount of product from the cart to the seeding bar and be able to continue to do that.
Some of the air seeder technology is tried and tested and has not changed much over the years, for example, the metering systems. But some aspects of the air seeder are all about change — and progress. Control panels and screens are now far more common on air seeders in a similar trend to tractors with guidance and telemetry equipment. And safety is also much higher up the priority list.
