Pneumatic precision seed drill Spirit 400-900C

discfor professional agriculturalfor large crops

Overview
Spirit 400-900C is a pneumatic Combi seed drill for combined seeding and fertiliser application, available in 4, 6, 8 and 9 m working widths. A large 5000 litre hopper with wide opening reduces refill frequency. High-capacity metering systems ensure reliable seed and fertiliser throughput, while machine design focuses on precise seed placement and simplified field operations.

Key features

• Pneumatic distribution and high-capacity metering for seed and fertiliser (combi versions with separate meters)
• Large 5000 L hopper with wide access for fast refilling
• Individual row depth control for uniform seed depth and emergence
• TriForce II® coulter suspension for consistent coulter pressure and terrain adaptation
• Wide press wheel with soft tyre profile and rear scrapers for improved slot closing and depth control
• Options for fertiliser placement: FIX, Nordic and InLine (depending on configuration)
• Operator control via Väderstad E-Control for in-cab adjustments and monitoring

Seed coulter — design and function
The seed coulter on Spirit 400-900C is engineered to maximize placement accuracy while minimising soil disturbance. The arrangement of seed discs, offset mounting and press wheel creates a narrow seed slot and consistent depth control at varying working speeds.

• Seed discs with sharp attack angle reduce opening pressure and help keep depth
• Offset-mounted discs lower draught and improve long-term stability
• Seed release ahead of disc centre places seed at the bottom of the slot for good soil contact
• Narrow seed slot minimises soil movement and eases slot closure
• High throughflow disc design improves performance in heavy residues
• Wide soft-tyre press wheel increases contact area for reliable slot closure across soil types
• Rear-mounted scrapers keep the press wheel clean to maintain consistent depth

TriForce II® seed coulter suspension
The TriForce II® suspension uses a triangular beam geometry to maintain set coulter pressure as terrain angle changes. This design keeps pressure consistent on each coulter, contributing to uniform seed depth and even emergence across the machine width.

Benefits

• Uniform seed depth across the full working width for even emergence
• Reduced draught and wear due to offset disc mounting
• Improved performance in crop residues thanks to high throughflow
• Better slot closure and soil contact from the wide press wheel and scrapers
• Wide operational range with extended coulter pressure capability (up to ~120 kg)
