Unparalleled accuracy
The Seed Hawk air drill provides the most precise seeding technology on the market. Delivering unmatched seed and fertiliser placement in one pass, it is perfect for all soil conditions. The Seed Hawk Air Drill comes in widths ranging from 12,2 m (40’) to 25,6 m (84’). Seed Hawk Air Drills can be configurated for 254 mm (10”) or 305 mm (12”) row spacing.
Nutrient use efficiency
Placing seeds in firm, moist soil enables roots to quickly access moisture and nutrients, promoting strong growth.
Quick and even germination
The double-knife system ensures precise seeding depth and excellent seed-to-soil contact, leading to outstanding emergence.
Precision seed-to-fertiliser placement
The fertiliser is covered with soil before dropping the seed. This prevents fertiliser burn and allows the seed early access to nutrients.
A seed’s greatest potential is at the time it is placed in the ground. For over 30 years, Seed Hawk’s innovative opener design has been the heart of the Seed Hawk Air Drill. Each independent dual-knife opener and packer assembly provides the precision seed-to-fertiliser placement required for outstanding emergence. Seed Hawk toolbars are offered in a variety of sizes with multiple spacing and seed placement options, enabling you to choose the right fit for your operation.
Superior conditions for growth
Germination is a crucial phase in the growth process. For strong emergence, it is vital that the plant quickly and safely accesses nutrients, giving it the early advantage it needs.

Key factors for healthy seed germination
Placing seeds in firm, moist soil allows roots to quickly access moisture and nutrients, fostering strong growth. Techniques like tine coulter furrows and micro-strip tillage optimise temperature, moisture retention, and air exchange, speeding up germination and boosting plant development.

Root development
Positioning the seed in firm, moist soil guarantees the radicle immediate and continuous access to moisture. The fine tilth adjacent to the seed facilitates the development of other roots, enabling them to swiftly extend towards the fertiliser band. This promotes rapid emergence and vigorous growth of the young plant.
-
Quick warm-up
For seed growth to begin, the seed furrow must reach the right temperature. The furrow created by the tine coulter functions similarly to strip tillage, warming up faster than the surrounding soil and speeding up germination. Higher temperatures also enhance fertiliser uptake and accelerate mineralisation, further promoting plant growth. Additionally, the stubble helps prevent wind from cooling the surface.
-
Promotes growth
The flat-faced design of the knives creates fine tilth, ensuring optimal seed-to-soil contact. Additionally, the knives form 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 retention
Moisture is crucial for successful germination. The Seed Hawk micro-strip tillage concept utilises both surface and ground moisture, directing them to the furrow. The fine tilth within the furrow reduces evaporation, while immediate consolidation retains moisture for the seed.
The Seed Hawk coulter
Seed Hawk’s industry-leading tine coulters operate independently for superior shallow seeding, depth accuracy, and optimal fertiliser placement. The dual-knife system ensures precise separation of fertiliser and seed, preventing fertiliser burn and promoting early nutrient access. The result is quick, uniform germination, even packing, and consistent performance in all soil conditions.
-
Efficiency in one pass
At the core of all Seed Hawk seeding systems is the tine coulter assembly. Each Seed Hawk tine coulter follows the ground independently by pivoting at the frame, managing fertiliser and seed placement, as well as packing the soil in a single pass.

➊ Fertiliser placement
The fertiliser knife features a pronounced forward angle, functioning similarly to a cultivator point but without the mixing properties. It elevates moist soil and shifts larger clods aside, leaving fine tilth in the seed slot. Its ability to penetrate soil ensures maximum depth with minimal weight, conserving diesel.
-
âž‹ Seeding
The seed knife, angled backward, carves a shelf from the sidewall and dresses it with fine tilth. Soil covers the fertiliser before the seed is placed on the shelf, ensuring perfect separation. This barrier prevents fertiliser burn and enhances seed-to-soil contact for rapid germination. The lateral separation ensures seeds are not placed directly on top of the fertiliser, avoiding broken capillarity and moisture competition. The short distance allows roots quick access to nutrients.
-
➌ Reconsolidation
The working depth of the Seed Hawk tine coulter is maintained by the packer wheel, which follows the ground surface directly behind the fertiliser and seed knives. The hydraulic cylinder applies downforce on the wheel, resulting in up to 150 kg of pressure. Adjustable packing pressure ensures excellent results in any soil condition. The Seed Hawk tine coulter consistently maintains its selected working depth, resulting in an evenly maturing crop every time.
Seed knives designed for performance
The Seed Hawk knives have been specifically designed to prevent hair pinning and/or mixing. Therefore, the seed is granted a clean seed slot free of residues.
-
Versatile seed placement options
Seed Hawk offers multiple seed placement options to meet the conditions and goals of each grower. Each option provides features and qualities suited to various conditions and objectives. Choose between Single Side Band (SSB), the new Inline Side Band (ISB), or Twin Wing (TW) knives based on your preferences.

-
Single Side Band knife
The Single Side Band Knife is the leader in precision seed and fertiliser placement. The offset knives cut shallow, separate trenches for seed and fertiliser, placing seed on undisturbed soil and fertiliser in the best position for superior uptake, while also protecting seedlings. The result is quicker germination and more even emergence in all soil conditions.
Available in 25.4 cm (10”) or 30.5 cm (12”) row spacing.
-
Inline Side Band knife
The Inline Side Band knives achieve side band placement with an inline knife design. The seed knife cuts a separate shallow trench where an angled seed tube is used to place the seed 5 cm (2”) away from and 1.9 cm (0.75”) above the fertiliser. The new inline design allows for better soil flow and performance in residues, resulting in a smoother field finish. The new inline system also allows the grower to easily switch from Side Band to Twin Row placement if desired.
Available in 25.4 cm (10”) or 30.5 cm (12”) row spacing.
-
Twin Wing knife
If narrower spacing is desired, growers have the option to equip their 30.5 cm (12”) toolbars with twin wing openers to create 22.9 cm (9”) of spacing between seeded rows. The design ensures that two distinct rows emerge, while providing proper separation of seed and fertiliser. The wider shank distribution improves residue clearance, and tighter row spacing increases seed bed use, making the emerging crop a better competitor for weeds.
Available in 30.5 cm (12”) row spacing, creating 22.9 cm (9”) rows.
Consistent seed depth with contour following
Seed Hawk 40-84 models come in 5- or 7-plex frame sections, allowing them to follow the contours of the land independently by pivoting at the frame. With a contour-following range of 46 cm (18”), the independent tine coulters deliver consistent seed depth, regardless of the terrain.
By controlling each row individually, each seed is granted the same optimal conditions for growth. Consistent contour-following ability is crucial in no-till operations where variable field conditions are present. The Seed Hawk tine coulter excels in this area.
Eliminate overlap with Sectional Control Technology™
Sectional control, combined with an independent GPS system, eliminates overlap, saves input costs, and reduces ground disturbance. It controls meters and openers to stop product flow and lift openers on previously seeded ground, preserving precision placement.
SCTx with Turn Compensation features an additional GPS receiver on the tractor for enhanced capabilities. This allows for more complex manoeuvres and precise control of air drill operations.
*SCTx is designed to complement units comprised of a Seed Hawk Air Seeder and a Precision Delivery Air Cart pairing. Additional components or pivot points between the tractor and the seeding unit are not supported and can alter the effectiveness of SCtx.
Wireless blockage monitoring
Now you can watch for blockages from the cab as the blockage system monitors product flow on your Seed Hawk seeding system. If a blockage is detected, it immediately delivers quick, accurate notification of the exact location to your iCon wireless control system.
Product leaving the manifold bounces off a stainless-steel membrane as it enters the seed or fertiliser run, creating a small sound wave. If there is any change in the sound wave, it is picked up by acoustic sensors that detect the blockage to trigger audio and visual alerts on your tablet.
When a blockage location is identified, you can take your tablet out of the tractor cab and carry it with you as you locate the blockage and fix the issue. No more misses.
Stainless steel primary lines
Seed Hawk 70-84 Air Drills are now updated with stainless steel primary lines. Stainless steel ensures growers the best possible experience, ensuring years of trouble-free operation with reduced maintenance. The stainless steel centre section is not included on tow-between versions of the Seed Hawk 70-84.
