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. The larger models come equipped with a steerable front axle. This ensures 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 efficient tapered fan design
• Axial piston hydraulic motor – highly efficient
• Fully welded aluminium impeller directly mounted to hydraulic motor – no external couplings or bearings to maintain
• Flow control valve prevents over-speeding of impeller – also 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 SR meterbox allow easy confirmation of product diversion or meter wheel condition.

TOUGH CONSTRUCTION FOR TOUGH CONDITIONS

Air seeders operate in harsh conditions. Fertiliser is corrosive. Gason air seeders are strongly built from the best materials and have a high-quality, corrosion resistant finish. 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

SIDE RELEASE METER BOX

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 METERING

• Ground drive metering is simple and reliable.


• Variable speed stepless gearbox controls meter shaft speed and application rate


• Uses the highly dependable ZeroMax gearbox (variator)


• Remotely adjusted from the left-hand side of the seeder


• Adjustment housing has easy to read indicator scale


• Lockable adjusting levers

VARIABLE RATE TECHNOLOGY (VRT)

Gason’s VRT system is state of the art with hydraulic drive and electronic control. It is one of the most controllable and rugged systems available.

• Change application rates at the touch of a button from the tractor seat using an electronic monitoring and control system
• Wide range of application rates
• High torque hydraulic motor handles the heaviest application rates, but will also operate at very low speeds for canola and summer crops
• Motor has very low oil requirements
• Accuracy is maintained regardless of temperature
• GPS compatible with full recording
• Failsafe manual override system
