Trailed GD Drill
The GD drill is the outcome of continuous refinement and development, to create a simple yet precise seed drill. It features the patented and future proofed GD coulter, which provides remarkably low soil disturbance, has a very low draught requirement along with an excellent service life. The GD drill excels in its adaptability to satisfy all drilling systems, soil types and conditions. This provides users with the flexibility to approach zero-till alongside traditional crop establishment methods. Trailed models are available in 3 to 8 Metre working widths helping to satisfy the demands of large farmers and contractors. The 5,000 Litre hopper (4,000L for the GD3001T) users ample volume whilst being fitted with an easily accessible volumetric metering unit accompanied by RDS iSOCAN controls. The tank can be configured to include an integral micro granular hopper. A closed hydraulic suspension system provides individual coulter pressure of up to 300Kg helping to maintain consistent sowing depth across undulations. Fitted with a Cat III linkage mounted drawbar allowing for tight headland manoeuvres. The hydraulic folding coulter bar maintains transport widths of under 3 metres on all models.



HOW THE COULTER WORKS
The principal behind the GD coulter design is based on a double disc arrangement, mounted on a 25° angle off the vertical which is able to pivot around a central kingpin mounted within the coulter body. The larger leading outer disc cuts an opening slice in the soil whilst the smaller inner disc is in effect undermining the ‘upper’ side forming an opening for the seed to be placed precisely. This process removes side wall compression from the opening slot, making slot closing more effective and consistent. The lifted wall of the soil is firmed down onto the seed by a single press wheel ensuring good seed to soil contact. The press wheel also acts as a depth regulator for the disc coulters. Drilling depth is adjusted by moving a single pin through a bank of holes with a depth range of 16-144mm in 16mm increments. Coulters are individually pressurised by a hydraulic system providing up to 200kg of downwards pressure helping to maintain consistent contact with the ground and follow contours and undulations. This refined design aided by an inter-row clearance of 1 metre has resulted in a coulter that is able to work in extremely trashy conditions and cover crops minimising the opportunity for hair-pinning to arise.
