СЗ 2.

Engineering design of the SZ 2.

The SZ 2. model is designed as a robust mechanical seeder, focusing on durability and operational consistency in various field conditions. The unit is built upon a rigid frame structure, which is engineered to withstand significant stress when operating across uneven terrain, ensuring that seeding depth remains stable throughout the entire run.

Metering and Seeding Mechanics

The core of the unit features fluted-roll metering devices. The design ensures gentle handling of seeds, preventing mechanical damage while maintaining a consistent flow rate. Adjustment of the seeding rate is achieved through precise control of the roller working length, allowing the operator to switch between cereal, legume, or small-seed crops with minimal downtime.

• Coulter group: Double-disc coulters with staggered disc placement effectively cut through soil and residue, preventing plugging and ensuring clean furrow formation.
• Drive system: The chain-driven mechanism, synchronized with the wheel travel, ensures precise metering regardless of fluctuating tractor speed.
• Fertilizer integration: Independent hoppers allow for simultaneous application of fertilizers, directly supporting plant growth during the critical early stages of development.

The practical advantage of this model is its straightforward maintenance. Every friction point and adjustment mechanism is easily accessible, allowing for rapid field repairs without the need for specialized equipment or lengthy service intervals.
