Great depth keeping
Thanks to the angled design of the seed discs, less force is needed to open the soil at the right depth. This helps the seed drill keep a steady working depth, which improves accuracy and crop performance.
-
Reduced draught force
On Spirit 400–900S, the seed discs are set slightly apart to lower the draught force when opening the seed slot. This smart setup helps the discs stay in place longer, which supports accurate seeding and cuts down on maintenance.
-
Precise seed delivery
Seeds are dropped just in front of the middle of the seed disc. As the disc turns, it guides each seed to the bottom of the slot, where it can reach moisture quickly and begin growing well from the start.
-
Minimal soil disturbance
Thanks to its offset disc design, Spirit 400–900S opens a narrow seed slot while disturbing very little soil. This helps spread the seed evenly in the row and makes slot closing more efficient.
-
Higher throughflow
Spirit 400–900S features a slim seed coulter, thanks to its disc layout. This helps the machine handle more crop residue and tough soil conditions, improving overall drilling performance.
-
Versatile press wheel
Spirit 400-900S is equipped with a wide press wheel that helps the machine stay steady on the soil surface, even in changing conditions. The soft tyre shape increases ground contact, which improves slot closing and allows for flexible use in different field types.
-
Size minimises vibrations
Spirit 400–900S uses large seed discs and press wheels to reduce vibration during work. This helps the machine stay steady, which improves depth control and keeps seed placement consistent, even when working faster.
-
Clean wheel maintains seed depth
Spirit 400–900S uses a tyre and scraper setup that stops soil from building up on the wheel. This keeps the wheel clean and helps the machine place seeds at a steady depth, supporting even crop growth.
TriForce II® seed coulter suspension
The TriForce II® seed coulter suspension brings greater precision to the field. Thanks to its unique design, the coulter has an unmatched ability to maintain its set pressure, even when challenged by irregularities in the terrain. The result is a more consistent seed depth, leading to even germination and more uniform crop emergence.
Advanced computer modelling shaped the unique triangular beam, enabling the suspension to function like a “lower and higher gear” to deliver optimal pressure at all angles.
Even emergence
Uniform seed depth ensures crops grow evenly, enhancing plant competition and maximising yield potential.
Maximising yield potential
Avoid shallow or deep seed placement, which can lead to poor germination and potential yield loss.
Adapted for each field
TriForce II® is engineered for real-world conditions, recognising that every field is unique.
Extended pressure range
With up to 120 kg of coulter pressure, the seed coulter system expands its operational range. This enables high-performance seeding in light to medium soil conditions without compromising on precision.
Consistent seed depth
TriForce II® ensures that each individual seed coulter maintains its set pressure, even when the coulter arm is angled upwards or downwards due to field irregularities. This leads to a uniform seed depth, promoting even germination, consistent crop emergence, and improved yield potential.
Spirit 400-900S adapts to the field
When seeds are placed at the right depth, they grow at the right time and can better compete with weeds and pests. That’s why every detail of the Spirit 400–900S coulter is designed for accuracy, helping crops get off to a strong and even start.
Uneven ground
On Spirit 400–900S, every seed coulter is fitted to its own arm, so it can adjust to bumps and dips in the field. This helps keep the working depth steady across the full width, even when the ground isn’t level.
Varying soil types
Spirit 400–900S allows the operator to adjust coulter pressure from the cab while working, making it easier to handle different soil types. The wide press wheel keeps good contact with the ground, helping to maintain seed depth without needing constant pressure changes.
Hilly terrain
Spirit 400–900S uses active coulter pressure to keep seed depth steady on slopes and dips. The system quickly senses changes in the terrain and adjusts the pressure through automatic valves, helping to place seeds accurately even on uneven ground.
Smart control from the cab
Hydraulic depth setting and E-Control integration allow operators to monitor and adjust seeding parameters directly from the cab using an iPad. This streamlines setup and boosts operational efficiency, giving you full control on-the-go.
Modern control system
Spirit is equipped with the iPad-based control system Väderstad E-Control.
In addition to an extensive control and monitoring of the seeding process, the control system offers the possibility to adjust the working depth of the front tool, the seed coulters as well as the hydraulic following harrow, while driving on the field.
User-friendliness, cost-effectiveness and an easy to update system are some of the major advantages.

125mm row spacing for maximum yield
Competitiveness
A narrow row spacing gives the crop significantly better competitiveness against weeds—especially important as herbicide-resistant species become more common. Research shows that a 125 mm row spacing results in 20% fewer weeds compared to 150 mm, helping to protect yield and reduce reliance on chemical control.
Population distribution
A 125 mm row spacing improves population distribution by allowing greater spacing between seeds within the row. This not only supports healthier plant development but also helps reduce fungal pressure, contributing to a more resilient crop.
Canopy closure
Narrow rows close more quickly, reducing evaporation at a time when access to moisture is most critical. This helps preserve soil moisture and supports healthy crop development during early growth stages.
Full-scale seedbed preparation
Spirit 400–900S features strong front tools that can be adjusted from the cab during operation. For extra levelling, a CrossBoard can be added in front of the disc tool and set individually to match field conditions. Large packer wheels press the soil between the front tool and the seed coulters, creating a firm seedbed. This is especially useful in lighter soils or fields with loose ground after deep cultivation.
Contour following and high throughflow
Spirit 400–900S uses individually suspended disc arms to follow the shape of the field closely, giving each seed the same conditions. The open layout allows plenty of material to pass through, making it ideal for fields with heavy crop residue. Bearings are safely placed at the back of the disc for added protection.
Straight tracking for precision
Spirit 400–900S uses an X-disc arrangement in the front tool to help the machine stay in line behind the tractor, even on slopes. This setup supports accurate farming and makes the most of GPS and RTK guidance systems.
Stable angle at any depth
Spirit 400–900S uses a parallel linkage to keep the front tool at a steady angle, no matter how deep it’s working. The cone-shaped disc helps maintain this angle even as the tool wears over time.
Wheels designed for performance
Spirit 400–900S uses large-diameter packer wheels for a smooth ride, even at higher speeds. Their low rolling resistance and special tread pattern help reduce bulldozing and cut fuel use. The wide wheels help keep the field level across the full working width.
Each wheel is mounted on its own, making maintenance simple and accessible.
Double-acting middle packer for even emergence
Spirit 400–900S includes a hydraulically controlled middle packer positioned between the tractor wheels. It helps create even conditions across the full working width, supporting uniform crop emergence and improving stability when travelling on rough roads.
Offset improves agronomy and efficiency
In Spirit 400–900S, every other packer wheel is set slightly behind on a separate axle.
- This offset design helps reduce bulldozing and can cut draught force by up to 25%.
- The larger wheels give a smoother ride with fewer vibrations, helping to keep depth control accurate.
- Having two axles also increases soil contact, improving load-bearing ability.

Easy-to-use tramlining
The dynamic tramlining function makes tramlining simpler and more reliable than ever before. The function is easy to setup with the iPad-based control system Väderstad E-Control. When seeding the field, the seed drill automatically shuts off specific rows when needed to match the tyre tracks of the sprayer.
Seed metering with high precision
Spirit 400-900S is equipped with the high precision metering system Fenix II that provides a constant and reliable seed metering. The strong motor permits high seed rates at high speed.
Additionally, the integrated fan runs at low speed, resulting in minimised fuel consumption and quiet operation. Its high location reduces the dust intake, thereby increasing drilling accuracy.
Large hopper with great access
To minimise downtime in the field, the Spirit 600–900S features a 5,000-litre hopper capacity, while the Spirit 400S offers 3,740 litres. The hopper is easy to fill thanks to its large opening and roll-up cover, which can be operated from ground level.
With two platforms and an open machine design, you benefit from excellent access to all components throughout the machine.

Automatic headland management
When lifting or lowering the seed drill at the headland, the automatic sequence control lifts or lowers the working zones one by one. When entering the field the system makes sure the front tool is lowered into the soil before the seed coulters and the following harrow.
By optimising this automatic lifting and lowering sequence, the seeding and fertiliser accuracy is enhanced at the headlands.
This system makes it possible to drill the headland first, without disrupting the result when drilling the rest of the field.
Save passes with BioDrill
By equipping Spirit 400-900S with the mountable small seeder BioDrill, a small seeded crop such as cover crops or ley, can be drilled together with the main crop.
The spreader plate distributes the seed very evenly in front of the following harrow.
An alternative way to use the BioDrill is for slug pellets, which are distributed through nozzles positioned behind the following harrow heavy. Slug pellet and seeder nozzles can be combined.
BioDrill provides an accurate seeding at the same time as saving passes on the field.
Product concept

Zone 2 - Consolidation
To ensure a firm seedbed prior to seed placement, large packer wheels consolidates the soil between the front tool and seed coulters. This offers great advantages in lighter soil, as well as in fields where the soil is loose as an effect of a deep cultivation or a cultivation with insufficient reconsolidation.
Zone 3 - Seed placement
Spirit has 380mm large discs for high speed accuracy. The OffSet discs move the soil to the side and place the seed in the bottom of the seed furrow. The soil falls back behind the discs and covers the seed with fine soil. The seed coulter pressure is up to 80kg to ensure a good penetration. The unique TriForce rubber suspension gives a supreme ability to follow ground contour.
Zone 4 - Reconsolidation
Each individual seed coulter has a wide coulter press wheel. This allows the seed coulters to respond to any irregularities or soil variations on the field, thereby ensuring the working depth is constantly maintained. The generous diameter of the coulter press wheel, further results in a smooth ride with minimal impacts from vibrations, thereby increasing precision at high speed.
Zone 5 - Finishing
The following harrow is positioned to run in-between the seed rows, so there is no risk of disturbing shallow-drilled seeds.The following harrow creates a loose evaporation barrier to preserve moisture and prevents capping after heavy rain.
