Mounted 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 most drilling systems, soil types and conditions. This provides users with the flexibility to approach zero-till alongside traditional crop establishment methods. The mounted GD Drill is a flexible and manoeuvrable direct drill suitable for all farm sizes. A slim line 1,600 Litre hopper (2,800 litres on the Grain & Fertiliser model) provides operators with ample capacity. Fitted with an easily accessible volumetric metering unit accompanied by RDS Artemis Lite controls, calibration is fast and simple. A closed hydraulic suspension system provides individual coulter pressure of up to 200Kg helping to maintain consistent sowing depth across undulations. A guide of 120HP + is recommended.
HOW THE COULTER WORKS
The principal behind the GD coulter design is based on a double disc arrangement, mounted on a 22° 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.

Key Features
Seed Placement
The GD coulter is able to accurately place a wide variety of seed types and sizes whilst maintaining a consistent depth. Seed is delivered between the two discs of the coulter directly to the bottom of the soil opening. The disc coulter units of the GD Drill are independently mounted and hydraulically pressurised, allowing each coulter to maintain consistent contact with the ground. Contours, obstacles and undulations are no challenge for accurate seed placement. A rubber exhaust boot at the top of the coulter diffuses 50% of the air allowing controlled seed delivery to the soil and preventing seed bounce.
Soil Disturbance
The GD coulter offers superior soil disturbance control compared to other no-till drills on the market. The coulter eliminates the opportunity for fresh soil to be brought to the surface whilst the surface layer is left intact and therefore prevents fresh and dormant weed seeds from germinating. The leading outer disc cuts through the soil whilst the smaller inner disc undermines the soil structure creating an opening for the seed to be placed, before swiftly being firmed back to its original state.
Precise Metering
The Accord metering unit is equipped with RDS Artemis Lite controls. This guarantees a repeatable metering dose up to 400 kg/ha. Suitable for fine and coarse grains, with no need to replace the metering rollers. On the move seed rate adjustment from the comfort of the tractor cab. Functions include GPS forward speed monitoring, symmetric and asymmetric tramline control, area totals, fan tachometer and low seed level alarm.
Hydraulic Fan Drive
The GD Drill is fitted with a hydraulic fan drive. This reduces the RPM on the tractor, which in turn reduces fuel costs, gives more flexibility with air flow, and helps prevent wear and tear.
Grain & Fertiliser
For the GD3000M there is a choice between a single tank grain only model and a split tank Grain & Fertiliser model. Both models are equipped with the same standard features, but the twin tank of the Grain & Fertiliser model has a 2,800 litre total capacity, with a 50/50 split. The mounted Grain & Fertiliser models uses RDS iSOCAN controls with GPS forward speed monitoring, each individual metering unit can offer variable rate application on the move. Individual metering units supply different products to the coulter where they are mixed in the seed tube as it enters the ground.
Front Tank & GD Toolbar
Our GD drill can now be offered in a front tank and rear toolbar combination. Available in both grain only and grain & fertiliser specification, the front tank offers a versatile seeding option and improves weight distribution. A front tank setup offers the flexibility of using both a disc or tine toolbar depending on conditions.

Hydraulic Markers
£2,600
A serrated cutting disc to mark the surface of the soil allowing operators to align the centre of the machine at equal and parallel distances from their previous workings.
Avadex Applicator (240L)
£8,600
The Stocks Turbo Jet applicator with a capacity of 240 litres is a versatile and accurate 12 volt powered pneumatic applicator to meter and spread most small seeds. This applicator is commonly used to apply avadex or slug pellets with the measured material blown onto the seedbed surface via a separate distribution unit. Applicators can be configured to suit various working widths.
OSR/Slug/Fert Applicator (130L)
£6,400
The Stocks Rotor Meter applicator has a capacity of 130 litres enabling it to accurately and safely meters micro and full size granular material and small seeds. The electronically speed controlled (ESC) applicator uses GPS to automatically maintain application rate as forward speed varies with ‘on the go’ rate adjustment. The metered material is fed into the venturi of the seed metering unit via a pressurised air supply ensuring constant delivery of material. The combination of materials is evenly mixed in the metering unit and delivered via each coulter into the seedbed.
iSOCAN GPS Metering Upgrade

The GD3001M (Grain Only) is equipped with RDS Artemis Lite as standard but can be upgraded to RDS iSOCAN Controls. The benefit of the upgrade is being able to use up to 4 metering units or applicators, enabling dual cropping, fertiliser and Avadex applications. The iSOCAN software also monitors and controls tramlining, hopper level, fan speed alarms, variable rate controls, on the go seed rate adjustment and offers activity data (e.g., area worked and quantities applied). The iSOCAN software is ISOBUS compatible, allowing complete control via ISOBUS with the additional of an ISOBUS ready cable (see optional specification).

Testimonials
Jack Martin, Contractor, Staffordshire
2022 is my fifth-year direct drilling with the Weaving GD. I
drill everything from cover crops to cash and forage crops across a variety of
farms. I offer drilling as a service but also my experiences to help customers
get the most out of this system. My goal is to improve and build soil health in
simple ways so that the land can be more productive, using simple methods such
as good crop rotation, cover cropping and direct drilling which have helped to
create healthier crops and lessen disease and weed prevalence. The results on
my family’s farm are clear to see and we are producing top yields with much
less mechanical input establishing crops.
The GD is a very
well-built machine that has some great features. The cutting discs disturb next
to no soil which is great for soils with high seed burdens. I actually bought
my GD second hand direct from another farmer, but despite this, the service and
support from the Weaving Machinery Parts department and one of their
Technicians, Ed Pocock has been second to none. The technicians have been to me
within hours of a phone call and parts are on the farm the next day.
