Great Plains Adds 6-metre Models to Saxon Drills Range

Great Plains has added new 6-metre models to its existing line-up of 3 and 4-metre Saxon minimal disturbance drills. The grain only variant of the new 6-metre model was shown for the first time in the UK at the Cereals event, closely followed by its appearance at The Royal Highland Show in Scotland. A grain and fertiliser option is also available.

Equipped with the Great Plains Turbo Coulter discs, the Saxon is designed to meet the need for minimal disturbance and, if required, for cutting through and drilling into high volumes of residue. This, says Great Plains, makes the drill ideal for use in cover crop rotations where minimal soil disturbance is necessary to help prevent the emergence of yet-to-germinate grass weed seeds.

“Not only is the Saxon highly effective in reduced tillage establishment systems and across a wide range of soil types and conditions, it can operate very efficiently in no till conditions where the soil structure allows and can help to improve control of black-grass and other grass weeds,” said Great Plains Sales Director, David Holmes.

“The Turbo Coulter disc is of an innovative and well-proven Great Plains design,” he explained. “It offers excellent seed placement with minimum disturbance between the rows and reduced risk of hair-pinning. Each Turbo Coulter disc is in line with the trailing double disc 00 Series opener. The angle wave profile of the Turbo Coulter disc creates a mini-seedbed in a finely tilled 10 to 50mm strip of soil into which the seeds will actually be planted and provides every row with equal growing conditions. The flutes enter the soil perpendicular to the ground for maximum cutting performance with less down pressure. The same flutes exit the soil parallel to the ground for a controlled soil release, leaving the soil between the rows almost completely undisturbed.

“The ‘Double V’ press wheel option helps to cover the seed by pinching the slot, creating optimum soil to seed contact, especially when working without cultivation in wetter soils,” he added.

The 6-metre Saxon 600 models feature a 4000-litre capacity hopper, which for grain and fertiliser models, can be split 50/50 or 60/40 between grain and fertiliser.

The Turbo Coulter discs run ahead of a tyre packer, which says Great Plains offers the largest diameter and widest profile currently available on the market and provides highly consistent consolidation in front of Great Plains’ well proven 00 Series openers.

The new 6-metre drills sow 36 rows (at 167mm spacing) and 48 rows (at 125mm spacing). Each 00 Series coulter incorporates a seed flap guiding seed close to the opener bottom, eliminating seed bounce.

Hydraulically adjustable down pressure in the range of 40kg to 160kg ensures the coulters operate at consistent depth in all soil types. New opener rail geometry maximises the transfer of weight to the coulter and press wheel by keeping the coulter arm parallel to the ground. This ensures accuracy of seeding depth and control over down pressure especially in difficult conditions.

The seed distribution system is variable rate ready. It comprises injection-moulded seed distribution heads with optional tramline shut-offs and seed blockage monitors to accurately deliver seed to each coulter with the ability to shut off each row individually for wider row spacing if required.

Great Plains has introduced a new meter housing design for easy access and a new modular seed drum system. Seed calibration is also easy and convenient, says the manufacturer. With seed calibration mode selected from the cab, the operator simply walks to the rear of the drill where a dedicated pipe delivers the metered amount.

The new Saxons fold to 3m for transport, the transport weight being carried on the packer, with two wheels each side for stability and clearance fitted with low ground pressure 420/55 17 tyres. A full European lighting kit is fitted.

Hopper weigh cells can be fitted as an option. Working via the hydraulic control system, these ensure the hopper’s weight is evenly distributed right across the drill’s width no matter how much grain it contains.

Other options include new hydraulic sprung track eradicators, hydraulic full-width levelling board, press wheel scrapers and harrows, hydraulic bout markers, pre-emergence markers, air or hydraulic brakes and camera kits.

Control is via a Mueller ISOBUS-ready system and a choice of display terminals is available.
