Built stronger to last longer

Gason air seeders are strongly built from the best materials to protect them from harsh operating environments and corrosive fertilisers.  They last longer, require less maintenance and retain their value.

• Bins constructed from 2.5mm and 3mm sheet steel
• Folded corners for maximum strength
• All corners fully welded both inside and outside
• Bins painted in two halves for maximum internal corrosion protection
• Two coats of enamel baked to 120°C for 30 minutes
• Small components powder coated

Controlled Traffic and Tyre Equipment

Most models are available in 2m or 3m controlled traffic configurations. A castor wheel design is used on the smaller models to offer excellent manoeuvrability and the ability to reverse. Larger models come equipped with a steerable front axle to ensure accurate tracking of the seeder when working around hillsides.

Large floatation gripster type tyres are used on the full range of Gason air seeders.

Fan and Hydraulic Systems

The hydraulically driven fan is a very simple design and highly efficient. All hydraulic components are of the highest quality and designed for a long, trouble-free service life.

• Highly capacity and quiet tapered fan design
• Highly efficient Axial piston hydraulic motor 
• Fully welded aluminium impeller directly mounted to hydraulic motor – no external couplings or bearings to maintain
• Flow control valve prevents over-speeding of impeller and controls fan speed when using tractors with open centre hydraulics (no flow control)
• Bins pressurise automatically to ensure maximum conveying efficiency – no loss of air pressure or flow
• High-pressure, replaceable 10-micron filter ensures clean oil supply to motor

Shooting Options and Blending

All Gason air seeders are suitable for single, double or triple shooting, depending on the configuration of your tillage planter.  Easy to operate diverter levers place seed and fertiliser in separate primary tubes or in a combination of blends.  Removable clear panels on the Side Release meter box allow easy confirmation of product diversion or meter wheel condition.

Side release accessibility

The Side Release (SR) meter box is another pioneering innovation from Gason that makes farming more efficient. Changing from one type of seed to another is a breeze. Sliding out the metering shaft assembly and cleaning can be accomplished in a couple of minutes – without crawling under the machine. You can also fit reduction plates for metering canola and other small seeds in a similar time.

• Ease of access
• Quick cleaning
• Swing away hatch allows easy removal of product from bin and for calibration access
• Easy changeover of metershaft assembly

Ground Drive or Variable Rate Technology (VRT)

Metering accuracy is assured with either Ground Drive or Variable Rate Technology (VRT).

Ground drive metering is simple, reliable and ideal for those not requiring the sophistication of VRT.  VRT’s advantage is superior functionality that will provide for all your future needs. VRT allows on the go application rate changes from the tractor cab. It is perfect for those using or considering prescription farming practices allowing the integration of GPS mapping technologies.

Both systems are extremely easy to calibrate.
