The Seed Hawk 600-900C is a no-till seed drill available in 6, 8, and 9 metre working widths. Its tine coulters create a clean seed slot, placing both seed and fertiliser on undisturbed soil. With a 7,000-litre hopper divided into three compartments, the machine provides the versatility required for modern farming.
The double-knife system ensures precise seeding depth and excellent seed-to-soil contact, leading to outstanding emergence.
No compromises are made regarding seed slot hygiene or fertiliser placement, enhancing the chances of success with no-till seeding across varying conditions throughout the crop rotation.
Seed Hawk employs micro strip-tillage to optimise no-till seeding. This minimises the risk of yield variations, while ensuring the crop is safeguarded from erosion and soil structure damage.
Seeding is the operation that sets the foundation for crop performance throughout the year. It is crucial to choose a seeding system that not only produces crops of the highest quality and yield but also performs reliably under all weather conditions. Give your crop the best chance to succeed while reducing risks at the same time.
By incorporating the key benefits of tillage into a no-till system, Seed Hawk combines the best of both worlds. The key to success is creating fine tilth near the seed and ensuring a seed slot free from residues that could hinder early crop development.
Seed Hawk delivers high germination rates, enabling seed savings. No compromises are made on seed slot hygiene or fertiliser placement, enhancing the chances of success with no-till seeding across various conditions throughout the crop rotation.

Small seeds, such as oilseed rape, are generally challenging in no-till conditions, as they require a very shallow seedbed and fine tilth coverage for even germination. Oilseed rape is also highly sensitive to fertiliser-induced seed burn. Seed Hawk creates an ideal seedbed structure on uncompacted soil with safe fertiliser separation, ensuring quick germination and strong plant development.
Seed Hawk is equipped with a double-acting tine coulter, featuring two separate knives that follow the ground contours. Combined with a frame that adapts to the field terrain, this ensures excellent depth precision and even germination. A uniform crop, growing and maturing evenly across the field, is essential for effective crop management throughout the growing season. A Seed Hawk field is characterised by its perfect green lines, where every plant enjoys the same conditions — an ideal start for a healthy crop.
Tine coulters are an ideal solution for creating fine tilth in the seed slot. The Seed Hawk knives ensure a clean, hygienic seed slot free from residues, preventing hair-pinning. The Seed Hawk tine coulter features two knives, with the fertiliser placed via the first knife, separated from the seed but close enough for quick access. The second knife goes more shallow a little to the side. While placing the seed and fertiliser, the knives perform a shallow, focused tillage operation where it is needed most to ensure crop performance. This focused micro-strip tillage minimises the risk of yield variations while protecting the crop from erosion and soil structure damage.
Germination is the most critical stage of the growth process. It is essential for the plant to access nutrients quickly and safely to gain the early advantage it needs for strong emergence.
Placing seeds in firm, moist soil enables roots to quickly access moisture and nutrients, promoting strong growth. Techniques such as tine coulter furrows and micro-strip tillage ensure optimal temperature, moisture retention, and air exchange, accelerating germination and enhancing plant development.

The seed is placed on firm, moist soil, ensuring the radicle has immediate and continuous access to moisture. The fine tilth beside the seed allows other roots to develop and rapidly branch out toward the fertiliser band. This promotes quick emergence and vigorous growth of the developing plant.
To trigger seed growth, the right temperature must be reached in the seed furrow. The furrow created by the tine coulter acts similarly to strip tillage, where the strip warms up faster than the surrounding soil, speeding up the germination process. Higher temperatures also increase fertiliser uptake and accelerate mineralisation, further boosting plant growth. Additionally, the stubble prevents wind from cooling the surface.
The flat-faced design of the knives creates fine tilth, ensuring optimal seed-to-soil contact. Additionally, the knives create an open sidewall and furrow bottom free from compaction or smearing, promoting air and moisture exchange as well as root development. Both the fertiliser and seed are placed on uncultivated soil, providing excellent access to capillary water, which ensures rapid seed swelling.
Moisture is essential for safe germination. The Seed Hawk micro-strip tillage concept benefits from both surface moisture and ground moisture being transported to the furrow. The fine tilth in the furrow minimises evaporation, while immediate consolidation preserves moisture for the seed.

To ensure field performance when seeding directly in heavy crop residues or after cover crops, the Seed Hawk knife coulter can be complemented with a front disc as an option. The front disc ensures thorough residue incorporation and can be adjusted independently. This versatility enhances seeding in cover crops, wheat stubble, and light soils, extending the machine’s range in high-residue conditions.
The fertiliser knife has a strong forward angle and acts similarly to a cultivator point, though without the mixing capabilities. It lifts moist soil and pushes larger clods to the side, leaving fine tilth in the seed slot. Its soil-penetrating ability ensures maximum depth with minimal weight requirements, saving diesel.
The seed knife, with its backward angle, carves a shelf from the sidewall and dresses it with fine tilth. The fertiliser is covered with soil before placing the seed on the shelf, ensuring perfect separation. This creates a barrier between the seed and fertiliser, preventing fertiliser burn and promoting seed-to-soil contact and fast germination. The lateral separation ensures no seed is placed on top of the fertiliser, avoiding broken capillarity and moisture competition. The distance is short enough to allow roots quick access to nutrients.
The Seed Hawk press wheel seals moisture in the fertiliser row while preventing capping over the seed, ensuring ideal seed-to-soil contact. Positioned behind the knives, it runs in tilled soil, maintaining consistent seed depth and ensuring smooth, precise operation.
No-till seed drills have traditionally been a choice between a disc or tine coulter. The tine coulter's main disadvantage has been its inability to cope with heavy residues due to blockages. The front disc on Seed Hawk changes this.
By combining the versatility of a disc coulter with the microclimate created by the dual-knife tine coulter, Seed Hawk offers the best of both worlds. This allows it to handle conservation agriculture systems with cover crops. It also improves performance for autumn oilseed rape establishment in wheat stubble and when seeding in light or organic soils with low resistance or high weed density.

With the front disc, the Seed Hawk 600-900C can extend its range into high-residue conditions. In some situations, the front disc can also allow for an increase in speed.
The front disc is mounted with a separate hydraulic cylinder, allowing it to be raised or lowered independently of the tine coulter. It is designed for a long working life, featuring a V-55 specially hardened Swedish steel disc and maintenance-free bearings. The disc runs in a linkage, making it insensitive to turns. The linkage is mounted with conical bushings to minimise wear.
The Seed Hawk features a 7,000-litre hopper divided into three compartments. Each compartment can be used to place product in either the seed or fertiliser knife. This also allows the mixing of two products in the same airstream. For example, a starter fertiliser, such as phosphorus, can be placed with the seed for quick access, boosting germination and root development.
The optional stainless steel filling auger can fill the hoppers at a capacity of 50 m³/h.
By controlling each row individually, every seed is provided with optimal conditions for growth. Consistent contour-following ability is crucial in no-till operations where variable field conditions are present, and the Seed Hawk coulter excels in this area.
The tine coulter follows the ground independently by pivoting at the frame. With a contour-following range of +/- 20 cm, each independent opener ensures consistent seed depth, regardless of terrain.

No-tillage seeding has traditionally involved a zero-tolerance approach to tillage, primarily to protect soil structure and fauna. However, this approach has sometimes resulted in high costs due to pests, performance problems, and unstable yields. Although the Seed Hawk 600-900C performs exceptionally well in no-tillage seeding on its own, pairing it with the CrossCutter Disc further reduces the risks associated with no-till farming. The ultra-shallow tillage delivered by the Carrier disc cultivator, fitted with the CrossCutter Disc, provides new possibilities.

Front disc
The front disc ensures efficient operation in trashy or cover crop conditions. It is operated by a separate hydraulic system but is included in the section lift.
The fertiliser knife has a strong forward angle and functions similarly to a cultivator point, though without the mixing capability. It lifts moist soil and pushes larger clods to the side, leaving fine tilth in the seed slot. Its soil-penetrating ability ensures maximum depth with minimal weight requirements, thus saving diesel.
The seed knife, with its backward angle, carves a shelf from the sidewall and dresses it with fine tilth to promote seed-to-soil contact and rapid germination. The Seed Hawk dual-knife coulter ensures exceptionally high germination rates, allowing for low seed rates.
The Seed Hawk press wheel applies more pressure on the fertiliser row to seal in moisture and aid dissolution. By applying slight sideways pressure over the seed, the press wheel prevents capping, ensuring perfect contact between seed and soil. The packer wheel is positioned behind the two knives, ensuring it always runs in tilled soil. This prevents minor surface variations from affecting the seed depth where it is neither intended nor needed. Consequently, the tine coulter operates smoothly and delivers excellent depth precision.
