New range makes sowing more efficient

Available in fixed frame sizes from three metres up to five metres and folding wing sizes from five metres up to seven metres, the GD Series seeders have been specifically designed to suit the challenging New England conditions.

The fixed frame models are available with a hydraulically operated end tow.

The operator simply removes the locking pin, and then the drill hydraulically rotates to allow it to travel down the road, and through gateways.

The folding wing models all fold up to 3.5m transport width, for easy access through narrow gateways and road travel.

All folding wing models feature hydraulically adjustable down pressure on the wings.

This allows the wings to float through soft ground, whilst still allowing the full weight of the chassis to be transferred to the wings in hard going.

The key to the new series of seeders is the double disc unit.

It features a trailing arm pivot design, allowing for excellent ground following abilities without compromising on strength.

The trailing arm design has good ground following and much better rock handling than a tine mounted disc.

"When a tine mounted disc unit hits a rock, it has to trip a long way backward before it starts to move up over the rock," Graytill owner Dave Grayling said.

"This increases wear and tear as the tine unit slams back into working position after the rock.

"Conversely, the trailing arm design allows the disc unit to gently ride up and over the rock with very little backward movement.

"The double disc unit features large 46cm (18 inch) discs for outstanding rock handling and reduced wear rates.

"The leading disc is scalloped for improved trash handling.

"The discs feature a sealed maintenance free bearing for reduced down time and maintenance costs."

Sowing height is controlled by a steel gauge wheel mounted directly to the sowing disc which is ideally suited for pastures at a fixed depth.

"Our customers are mostly sowing pasture at the same depth all the time, so it takes the guess work out of getting the seed placement right," Mr Grayling said.

"When cereals are being planted, and a deeper sowing depth is required, the gauge wheels can be easily removed and replaced with smaller wheels for deeper sowing, or eliminated completely, in which case the depth is set by machine height, the same as a traditional combine."

All the GD Series machines are available on row spacings as narrow as 100mm (four inches).

"The narrow spacing is ideal for pastures in higher rainfall areas," Mr Grayling said.

"It gives quicker coverage, giving weeds less chance to germinate and reducing intra row competition between plants.

"The GD Series seeder feature Graytill's proven SB series seed bins.

"Capacities of 1000 and 1500 litres per bin mean less time is spent filling, and more time is spent sowing.

"The bins feature a quick-change roller system that allows the bin to be cleaned out and changed from small seeds to large seeds in less than five minutes.

"The metering design allows a large range of products and rates to be sown, from small seeds as low as 1kg/ha through to large seeds sown at rates over 300kg/ha."
