Planting methods PROSEM SYSTEM PRECISION PLANTERS
The PROSEM K seeding row unit is designed to ensure precise and reliable planting in precision seeding, combining robust mechanical construction with technical solutions aimed at consistent germination and ease of use.
The assembly is based on an articulated parallelogram system, which allows effective ground tracking and ensures the stability of the seeding unit throughout its entire travel. This design maintains a constant working geometry of the row unit, promoting a uniform planting depth, even in conditions of micro-relief or surface variability.
Seed metering is carried out by a vacuum distribution system, fitted with interchangeable discs and constructed from high-strength engineering polymers. This system guarantees high precision in seed singulation, adapting to different seed types with low maintenance and high reliability in the field.
The opening system is based on a 15” diameter double disc with a low angle of attack, which optimises penetration and minimises soil disturbance. This configuration promotes the formation of a clean, even furrow, improving soil-seed contact and reducing power requirements.
Spring-loaded pressure adjustment with indexed positions allows the load applied to the row unit to be adjusted quickly, adapting it to different soil conditions and levels of preparation. Depth control is carried out directly at the seed drop point via limit wheels, which increases planting precision.
The assembly is completed by a reliable and easy-to-maintain mechanical chain transmission, as well as multiple configuration options (closing wheels, scrapers, residue deflectors, etc.) that allow the row unit to be adapted to different farming scenarios.
In operational terms, the PROSEM K stands out for its structural robustness, stability in operation and precision of the metering unit, offering an optimal balance between agronomic performance and simplicity in mechanics.
